Abstract
PURPOSE Persistent diabetic macular edema (DME) remains a problem in clinical practice, with many patients having a suboptimal response to the standard of care (SOC). Evidence supports the long-term efficacy of intravitreal fluocinolone acetonide (FAc) implant (ILUVIEN®) in patients that have responded sub-optimally, although there is still scarce data from real-world Portuguese practices. We aimed to monitor the current SOC in selected Portuguese practices prior to FAc implantation and then assess the long-term effectiveness and safety of the FAc implant. SETTINGS The study included patient data from five Portuguese public hospitals. DESIGN This was a non-interventional, multicenter audit of data collected from Retina.pt registry from patients with persistent or recurrent DME despite treatment. METHODS Outcome measures included changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP). Results were compared at regular times over 36 months. RESULTS This study included 222 eyes from 152 patients. A significant decrease in BCVA (P < 0.001) and a significant increase in CMT (P = 0.013) were observed prior to FAc. A significant increase in BCVA was registered at 6 months after FAc implant administration (P < 0.001), which was maintained during follow-up. No relevant changes in IOP were observed. Treatment burden was reduced as a result of treatment with FAc (P < 0.001 for anti-VEGF, corticosteroids, or both treatments) in the full population. CONCLUSIONS In Portuguese practice, data showed that pre-FAc implantation, some patients did not respond to SOC treatment and/or they were undertreated. Following FAc implant administration, there were rapid, sustained, long-term visual and anatomical improvements, and a marked reduction in treatment burden.

Switching to an Intravitreal Dexamethasone Implant after Intravitreal Anti-VEGF Therapy for Diabetic Macular Edema: A Review. Life (Basel) 2024; 14:725. [PMID: 38929708 PMCID: PMC11204630 DOI: 10.3390/life14060725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 05/27/2024] [Accepted: 06/01/2024] [Indexed: 06/28/2024] Open
Abstract
Among working-age people, diabetic retinopathy and diabetic macular edema are currently considered the main causes of blindness. Nowadays, intravitreal injections are widely acknowledged as a significant milestone in ophthalmology, especially for the treatment of several retinal diseases, including diabetic macular edema. In particular, anti-vascular endothelial growth factor (VEGF) agents are typically the first line of treatment; however, monthly injections are required, at least, during the loading dosage. Notably, an intravitreal 0.7 mg dexamethasone (DEX) implant (Ozurdex®, AbbVie Inc., North Chicago, IL, USA) is considered a legitimate substitute treatment for diabetic eyes that have not responded to anti-VEGF treatment. In fact, clinical trials and real-life studies have demonstrated the effectiveness and safety of an intravitreal DEX implant in treating such conditions over a period of three to six months. For this reason, wisely selecting diabetic patients might be crucial to decreasing the load of injections in clinics and hospitals. The purpose of this review is to analyze the available scientific literature to highlight the benefits, efficacy, and clinical criteria for choosing whether to switch from intravitreal anti-VEGF therapy to an intravitreal DEX implant in diabetic macular edema.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy and safety of aflibercept (AFL) versus ranibizumab (RAN) for the treatment of diabetic macular edema (DME). METHODS The PubMed, Embase, Cochrane Library, and CNKI databases were searched up to September 2022 to identify prospective randomized controlled trials (RCTs) comparing AFL with RAN for the treatment of DME. Review Manager 5.3 software was used for data analysis. We used the GRADE system to evaluate the quality of the evidence for each outcome. RESULTS A total of 8 RCTs involving 1067 eyes (939 patients) were included; there were 526 eyes in the AFL group and 541 eyes in the RAN group. Meta-analysis revealed that there was no significant difference between RAN and AFL in the best-corrected visual acuity (BCVA) of DME patients at 6 months (WMD: -0.05, 95% CI = -0.12 to 0.01, moderate quality) and 12 months after injection (WMD: -0.02, 95% CI = -0.07 to 0.03, moderate quality). Additionally, there was no significant difference between RAN and AFL in the reduction of central macular thickness (CMT) at 6 months (WMD: -0.36, 95% CI = -24.99 to 24.26, very low quality) and 12 months after injection (WMD: -6.36, 95% CI = -16.30 to 3.59, low quality). Meta-analysis showed that the number of intravitreal injections (IVIs) for AFL was significantly lower than that for RAN (WMD: -0.47, 95% CI = -0.88 to -0.05, very low quality). There were fewer adverse reactions to AFL than to RAN, but the difference was not significant. CONCLUSION This study found that there was no difference in BCVA, CMT or adverse reactions between AFL and RAN at 6 and 12 months of follow-up, but AFL needed fewer IVIs than RAN.

Abstract
PURPOSE To assess the effectiveness of switching intravitreal dexamethasone implants (DEX-implant) from pro re nata (PRN) treatment regimen to a proactive regimen in patients with macular edema of diverse etiologies. DESIGN An observational, retrospective, uncontrolled, multicenter, national case series. PARTICIPANTS Eighty-one eyes from 68 patients treated between October 2015 and June 2023 were included. METHODS This study included consecutive eyes treated with DEX-implant who were switched from a PRN regimen to a proactive regimen for diabetic macular edema (DME), retinal vein occlusion (RVO), noninfectious uveitis macular edema (UME; including postsurgical macular edema), and radiation maculopathy (RM). MAIN OUTCOME MEASURES The main outcome measures were change in the best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) at each visit. RESULTS According to the etiology, DME represented 49.4% of eyes, UME 24.3%, RVO 21.0%, and RM 6.2%. The mean (standard deviation [SD]) duration of follow-up under the PRN and proactive regimens was 20.6 (13.3) and 14.2 (10.3) months, respectively. Switching from a PRN to a proactive regimen significantly improved mean (SD) BCVA by 3.7 (12.9) ETDRS letters (P = 0.01) with a mean (SD) decrease in CMT of 108.0 (151.4) μm (P < 0.001). The proportion of visits with significant anatomic recurrence (> 50 μm) also decreased from 40.1% to 6.0% after switching to a proactive regimen (P < 0.001). The number of DEX-implant injections significantly increased during the proactive treatment period (P < 0.001), but the change in the number of visits was not significantly different (P = 0.2). The proactive treatment period was not associated with a significant increase in IOP (P = 0.6). CONCLUSIONS Switching to a proactive regimen in patients already treated with DEX-implant seems to significantly improve BCVA and CMT while maintaining stable IOP.

Abstract
The high prevalence of Diabetic macular edema (DME) is a real global health problem. Its complex pathophysiology involves different pathways. Over the last decade, the introduction of intravitreal treatments has dramatically changed the management and prognosis of DME. Among the different treatment options, inhibitors of vascular endothelial growth factor (anti-VEGF) and intravitreal steroids implants represent the first-line therapy of DME. We conducted a review of electronic databases to compile the available evidence about the clinical management of DME in a clinical setting, with a special focus on treatment-naïve patients. Anti-VEGF therapies represent a valuable option for treating DME patients. However, many patients do not respond properly to this treatment and, due to its administration regimen, many patients receive suboptimal treatment in real life. Current evidence demonstrated that in patients with DME, DEX-i improved significantly both anatomic and visual outcomes. Besides eyes with insufficient anti-VEGF respond or recalcitrant DME cases, DEX-i can be effectively and safely used in treatment-naïve DME patients as first line therapy. DEX-i may be considered first line therapy in different clinical scenarios, such as DME eyes with a greater inflammatory component, patients with cardiovascular events, vitrectomized eyes, or those requiring cataract surgery. In conclusion, there are still many points for improvement pending in the clinical management of the patient with DME. Since DME treatment must follow a patient-tailored approach, selecting the best therapeutic approach for each patient requires a good understanding of the pathophysiology of DME.

Abstract
Diabetic macular edema (DME) is a common complication of diabetes mellitus and a leading cause of visual impairment worldwide. It is defined as the diabetes-related accumulation of fluid, proteins, and lipids, with retinal thickening, within the macular area. DME affects a significant proportion of individuals with diabetes, with the prevalence increasing with disease duration and severity. It is estimated that approximately 25-30% of diabetic patients will develop DME during their lifetime. Poor glycemic control, hypertension, hyperlipidemia, diabetes duration, and genetic predisposition are recognized as risk factors for the development and progression of DME. Although the exact pathophysiology is still not completely understood, it has been demonstrated that chronic hyperglycemia triggers a cascade of biochemical processes, including increased oxidative stress, inflammation, activation of vascular endothelial growth factor (VEGF), cellular dysfunction, and apoptosis, with breakdown of the blood-retinal barriers and fluid accumulation within the macular area. Early diagnosis and appropriate management of DME are crucial for improving visual outcomes. Although the control of systemic risk factors still remains the most important strategy in DME treatment, intravitreal pharmacotherapy with anti-VEGF molecules or steroids is currently considered the first-line approach in DME patients, whereas macular laser photocoagulation and pars plana vitrectomy may be useful in selected cases. Available intravitreal steroids, including triamcinolone acetonide injections and dexamethasone and fluocinolone acetonide implants, exert their therapeutic effect by reducing inflammation, inhibiting VEGF expression, stabilizing the blood-retinal barrier and thus reducing vascular permeability. They have been demonstrated to be effective in reducing macular edema and improving visual outcomes in DME patients but are associated with a high risk of intraocular pressure elevation and cataract development, so their use requires an accurate patient selection. This manuscript aims to provide a comprehensive overview of the pathology, epidemiology, risk factors, physiopathology, clinical features, treatment mechanisms of actions, treatment options, prognosis, and ongoing clinical studies related to the treatment of DME, with particular consideration of intravitreal steroids therapy.

Abstract
BACKGROUND AND OBJECTIVE Intravitreal dexamethasone implant (DEXI) has been placed as an effective option to treat diabetic macular edema (DME). However, there is no consensus on the best time to introduce it. We conducted a study to evaluate anatomical and functional behavior after the first DEXI according to previous treatment. RESEARCH DESIGN AND METHODS This retrospective, real-world study between 2013 and 2020 investigated changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT at months 2 and 6 after the first DEXI in DME. Patients were divided into naive, early switch (≤3 anti-VEGF injections), or late switch (>3 anti-VEGF injections) groups. RESULTS Among 112 consecutive eyes, mean BCVA and CMT improved significantly in all groups at month 2, with no difference between them. However, this improvement was not maintained at 6 months. The Naíve group presented better BCVA all over the study period. The previously treated groups, which started with worse initial visual acuity, showed more visual gain without reaching the BCVA of the naive group. CMT performance was similar between groups. CONCLUSIONS There was similar anatomical and functional behavior in all groups. Poorer visual acuity at baseline was associated with worse functional outcome despite good anatomic response.

Abstract
Randomised clinical trials (RCTs) are generally considered the gold-standard for providing scientific evidence for treatments' effectiveness and safety but their findings may not always be generalisable to the broader population treated in routine clinical practice. RCTs include highly selected patient populations that fit specific inclusion and exclusion criteria. Although they may have a lower level of certainty than RCTs on the evidence hierarchy, real-world data (RWD), such as observational studies, registries and databases, provide real-world evidence (RWE) that can complement RCTs. For example, RWE may help satisfy requirements for a new indication of an already approved drug and help us better understand long-term treatment effectiveness, safety and patterns of use in clinical practice. Many countries have set up registries, observational studies and databases containing information on patients with retinal diseases, such as diabetic macular oedema (DMO). These DMO RWD have produced significant clinical evidence in the past decade that has changed the management of DMO. RWD and medico-administrative databases are a useful resource to identify low frequency safety signals. They often have long-term follow-up with a large number of patients and minimal exclusion criteria. We will discuss improvements in healthcare information exchange technologies, such as blockchain technology and FHIR (Fast Healthcare Interoperability Resources), which will connect and extend databases already available. These registries can be linked with existing or emerging retinal imaging modalities using artificial intelligence to aid diagnosis, treatment decisions and provide prognostic information. The results of RCTs and RWE are combined to provide evidence-based guidelines.

Abstract
BACKGROUND Patients with pre-existing macular edema (ME) due to diabetes and retinal vein occlusions (RVO) make up a growing population receiving cataract surgery. Surgery is associated with an increased risk of worsening existing ME due to post-surgical inflammation that can be further exacerbated by pre-existing diabetic retinopathy (DR) and retinal vein occlusion. This study aimed to examine the pre-operative use of intravitreal dexamethasone (DEX) implants in patients with ME undergoing cataract surgery. METHODS A retrospective study was conducted at National Cheng Kung University Hospital in Taiwan involving 19 eyes of 16 patients with DME or ME associated with RVO. All participants received a DEX implant at baseline and underwent phacoemulsification within 3 months after its insertion. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) and central subfield thickness (CST) were evaluated. RESULTS DEX implants reduced the CST from baseline (357.8 μm) to pre-surgery (280.8 μm). This reduction below baseline continued to month 6 post-surgery (319.4 μm). From baseline (16.15 mmHg), the mean IOP initially increased pre-surgery (17.78 mmHg) before returning to the baseline value at month 6 post-surgery (16.15 mmHg). All patients improved their BCVA from logMAR 0.943 on average at baseline to logMAR 0.532 at month 6 post-surgery. CONCLUSIONS The results of the study suggested that patients with ME could benefit from DEX implants before cataract surgery within 3 months to achieve sufficient postoperative inflammation management and limit ME deterioration. DEX implants did not increase IOP post-surgery and was similar to baseline levels.

Visual and Anatomical Outcomes of a Single Intravitreal Dexamethasone in Diabetic Macular Edema: An 8 Year Real-World Study. J Clin Med 2023; 12:3878. [PMID: 37373573 DOI: 10.3390/jcm12123878] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2023] [Revised: 05/24/2023] [Accepted: 05/29/2023] [Indexed: 06/29/2023] Open
Abstract
IMPORTANCE Diabetic macular edema (DME) is a major cause of vision loss in patients with diabetes mellitus. Intravitreal dexamethasone is a treatment option for patients unsuitable for or non-responsive to anti-angiogenic agents. OBJECTIVE To quantify visual and anatomical outcomes from an initial intravitreal dexamethasone injection over the expected 6-month period of dexamethasone release by the implant. Design and enrolment: This is a retrospective cohort study using electronic medical records of patients reviewed between 1 January 2012 and 1 April 2022. SETTING A tertiary eye-care center in London, United Kingdom; Moorfields Eye Hospital National Healthcare System Foundation Trust. PARTICIPANTS The cohort comprised 418 adult patients with DME who received an initial treatment of 700 µg intravitreal dexamethasone in the study period. Of these, 240 patients met the inclusion criteria of ≥2 hospital visits following initial injection (≥1 beyond 6 months) and no previous ocular corticosteroid treatment or missing assessment at baseline. EXPOSURE(S) Intravitreal dexamethasone implant (700 µg). MAIN OUTCOME(S) AND MEASURE(S) Probability of a positive visual outcome, defined as ≥5 or ≥10 Early Treatment Diabetic Retinopathy Study (ETDRS)-letter gain after treatment when compared to baseline (Kaplan-Meier models). RESULTS From the initial intravitreal dexamethasone injection alone, we observed a >75% chance of gaining ≥5 ETDRS letters and >50% chance of gaining ≥10 ETDRS letters within 6 months. There was less than a 50% chance of sustaining either positive visual outcome beyond 4 months. CONCLUSIONS AND RELEVANCE Most patients can be expected to have a positive visual outcome following an initial injection of dexamethasone implants that subsides within 4 months. Real-world re-treatment was observed to be delayed until after visual benefits were lost in half of the cohort. Further research will be needed to study the effects of delays in re-treatment.

Abstract
INTRODUCTION To evaluate real-world efficacy, safety, and treatment patterns with the dexamethasone intravitreal implant (DEX) in diabetic macular edema (DME) in France. METHODS In this prospective, multicenter, observational, noncomparative, post-reimbursement study, consecutively enrolled patients with DME had a baseline evaluation on day 0. Those treated with DEX on day 0 were to be reevaluated at week 6 and months 6, 12, 18, and 24. DEX retreatment and/or alternative therapies were allowed during follow-up. The primary outcome measure was the maximum best corrected visual acuity (BCVA) gain from baseline during follow-up. Secondary outcome measures included time to maximum BCVA gain, patients (%) with prespecified BCVA gains from baseline at each visit, maximum central retinal thickness (CRT) reduction from baseline, patients (%) with CRT reduction ≥ 20% from baseline at each visit, patients (%) with DME resolution (per investigator judgement), and adverse events (AEs). RESULTS Of 112 patients/eyes with DME for 3.5 years (mean) at baseline, 80 (including 86.1% previously treated) received DEX on day 0 and were analyzed for efficacy. Early study termination precluded collection of ≥ 12-month efficacy data. Patients received 1.4 DEX injections over 8.3 months (averages). The maximum BCVA gain from baseline was 3.6 letters, reached after 77.2 days (averages); 24.6% (week 6) and 15.0% (month 6) of patients experienced ≥ 10-letter BCVA gains from baseline. The mean maximum CRT reduction from baseline was -146.4 µm; 61.4% (week 6) and 36.0% (month 6) of patients had CRT reductions ≥ 20% from baseline, and 68.1% reported DME resolution at least once during follow-up. Ocular hypertension (n = 8, 12.1%) was the most frequent treatment-related AE. CONCLUSIONS LOUVRE 3 confirmed that DEX improves BCVA and CRT, even in a patient population that had predominantly received DEX before enrollment in the study, and showed that DME resolution was observed during follow-up. DEX tolerability was consistent with published data, supporting treatment benefits in DME. CLINICALTRIALS GOV IDENTIFIER NCT03003416.

Abstract
OBJECTIVE To compare outcomes of cataract surgery combined with either anti-Vascular Endothelial Growth Factor (anti-VEGF) therapy or dexamethasone implant (DEX) in patients with diabetic macular oedema (DMO). METHODS Pubmed and Embase databases were searched for studies reporting outcomes of diabetic cataract surgery combined with either anti-VEGF or DEX, with a follow-up ≥3 months. The primary outcome was the mean change in central macular thickness (CMT). Mean change in best corrected visual acuity (BCVA) was considered as a secondary outcome. The mean difference between baseline and post-treatment values (MD) with 95%-Confidence Interval (95%CI) was calculated and meta-analyses were performed. RESULTS Nine-teen studies were included, 8 in the DEX group and 11 in the anti-VEGF group. A significant reduction of macular thickness was shown in the DEX group at 3 months (MD = -98.35 µm; 95% CI, -147.15/-49.54), while mean CMT change was non-significant in the anti-VEGF group (MD = -21.61 µm; 95% CI, -59.46/16.24; test of group differences, P < 0.001). At 3 months, no difference in visual gain was found between the two groups (P = 0.13). CONCLUSIONS In DMO patients, cataract surgery combined with DEX seems to provide better anatomical outcomes compared with cataract surgery combined with anti-VEGF therapy. However, our evidence was limited by significant heterogeneity. Randomised trials comparing these two different combined approaches are warranted.

Management of Patients with Diabetic Macular Edema Switched from Dexamethasone Intravitreal Implant to Fluocinolone Acetonide Intravitreal Implant. Pharmaceutics 2022; 14:pharmaceutics14112391. [PMID: 36365209 PMCID: PMC9693281 DOI: 10.3390/pharmaceutics14112391] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 10/13/2022] [Accepted: 10/20/2022] [Indexed: 11/09/2022] Open
Abstract
To assess anatomical and functional outcomes after switching from dexamethasone implant (DEXi) to fluocinolone acetonide implant (FAci) in 113 diabetic macular edema eyes, a multicentric retrospective observational study was conducted. Seventy-five eyes (73.5%) were switched 1−8 weeks after their last DEXi. The mean best-corrected visual acuity improved to 59.8 letters at month 4 and remained stable during the follow-up. The mean central macular thickness (CMT) significantly decreased during the follow-up, with a minimum of 320.9 μm at month 3. The baseline CMT was higher in eyes that received the last DEXi >8 weeks versus <8 weeks before the first FAci (p < 0.021). After FAci injection, additional treatments were needed in 37 (32.7%) eyes. A longer diabetes duration (p = 0.009), a longer time between the last DEXi and the first FAci (p = 0.035), and a high baseline CMT (p = 0.003) were risk factors for additional treatments. The mean intraocular pressure was <19 mmHg at all timepoints, with no difference between eyes receiving the last DEXi ≤8 weeks or >8 weeks before the switch. Switching from DEXi to FAci in DME is effective and safe. A short time between the last DEXi and the first FAci reduced CMT fluctuations and the need for early additional treatments.

Abstract
AIM LANDSCAPE aimed to estimate the annual incidence and prevalence of treated diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR) between 2008 and 2018. METHODS This French nationwide observational study used data from the French National Health Insurance Databases covering 99% of the French population. Data about healthcare consumption were used to identify adults treated with anti-VEGFs or dexamethasone implants (for DME) and with pan-retinal photocoagulation (for PDR). All French patients newly treated between 2008 and 2018 were included. Incidence and prevalence of treated DME and PDR were estimated for the age-matched general population and the population with diabetes in France. Sociodemographic characteristics and medical history were described in both populations. RESULTS We identified 53,584 treated DME patients and 127,273 treated PDR patients between 2008 and 2018, and 11,901 DME and 11,996 PDR new incident patients in 2018. The treated DME incidence in 2018 was 2.5 per 10,000 in the general population and 37.3 per 10,000 in the population with diabetes. Prevalence in 2018 was 9.5 and 143.7 per 10,000 in the respective populations. Treated PDR incidence in 2018 was 2.3 per 10,000 in the general population and 31.2 per 10,000 in the population with diabetes. Prevalence in 2018 was 19.9 and 270.3 per 10,000 in the respective populations. Incidence and prevalence were not age-dependent. Incidence of treated PDR incidence was relatively stable from 2008-2018. Incidence of treated DME incidence rose from 2012-2018, probably due to widening access to newly available treatments, such as anti-VEGFs. CONCLUSIONS We provide exhaustive nationwide data on the incidence and prevalence of treated diabetic ocular complications in France over a 10-year period.

Abstract
Introduction To evaluate real-life efficacy, safety, and treatment patterns with the dexamethasone intravitreal implant (DEX) in posterior segment inflammation due to non-infectious uveitis (treatment-naïve or not) in French clinics. Methods In this prospective, multicenter, observational, non-comparative, post-reimbursement study, consecutive patients with posterior segment inflammation due to non-infectious uveitis were enrolled and evaluated at baseline (day 0). Those who received DEX on day 0 were re-evaluated at months 2, 6, and 18. Retreatment with DEX and/or alternative therapies was allowed during follow-up. Primary outcome: patients (%) with at least a 15-letter gain in best corrected visual acuity (BCVA) at 2 months. Secondary outcomes included patients (%) with at least 15-letter BCVA gains at 6 and 18 months; mean BCVA change from baseline at 2, 6, and 18 months; and patients (%) retreated, mean central retinal thickness (CRT), and adverse events (AEs) at all post-baseline visits. Results Ninety-seven of 245 enrolled patients with posterior segment inflammation due to non-infectious uveitis (80% previously treated) and disease duration of 5 years (average) received DEX on day 0 and were included in efficacy analyses. At month 2 (n = 91), 20.5% of patients (95% CI 12.0–28.9) gained at least 15 letters from a baseline mean of 60.9 letters; the mean gain was 6.2 letters (95% CI 3.5–8.9). At month 6, 50.0% (n = 38/76) of patients did not receive alternative treatment or DEX retreatment, mostly because inflammation had sufficiently subsided (n = 27/38, 71.1%). Although early study termination prevented efficacy analysis at 18 months (n = 12), CRT reductions persisted throughout follow-up. From baseline to month 18, 21/245 (8.6%) patients had DEX-related AEs; 17/245 (6.9%) had ocular hypertension (most common AE). Conclusion LOUVRE 2 confirms DEX efficacy on visual acuity and CRT in predominantly DEX-pretreated patients with relatively old/stabilized uveitis. DEX tolerability was consistent with known/published data, confirming treatment benefits in posterior segment inflammation due to non-infectious uveitis. ClinicalTrials.gov Identifier NCT02951975.

Abstract
Objectives To compare short-term effect of intravitreal ranibizumab with dexamethasone implant for diabetic macular edema (DME) in vitrectomized eyes. Methods Single-center, prospective, randomized study of vitrectomized eyes with DME. Study eyes were divided into two groups, receiving ranibizumab (IVV group, n = 35 eyes) or dexamethasone implant (IVD group, n = 35 eyes) respectively. Patients were evaluated at baseline, Week 1 and Month 1. The main outcome measures included best-corrected visual acuity (BCVA), central retinal thickness (CRT) and intraocular pressure (IOP). Results BCVA and CRT were similar in the two groups at baseline. At Week 1, the CRT improvement was significant in two groups (P = 0.041 in IVV group, P = 0.030 in IVD group), but at Month 1, only IVD group had significant improvement in CRT (P < 0.001). And BCVA gains were significant at Week 1 (P = 0.029) and Month 1 (P = 0.001) in IVD group, whereas IVV group did not show significant BCVA gains (P = 0.056 at Week1, P = 0.166 at Month 1). The changes of BCVA and CRT were significantly higher in IVD group than IVV group at Month1, but the changes were not significant at Week1. Conclusions Comparing to anti-VEGF therapy, DEX implant is more effect in improving BCVA and reducing CRT in vitrectomized eyes at 1 month, which indicated DEX implant is a better strategy.

Abstract
Purpose To evaluate the influence of pars plana vitrectomy with internal limiting membrane peeling on recurrence time of diabetic macular edema in eyes under treatment with dexamethasone intravitreal implant injections. Material and methods Twelve pseudophakic eyes of 12 patients with non-proliferative diabetic retinopathy and non-tractional diabetic macular edema were included. All eyes had already been treated with two or more dexamethasone intravitreal implant injections evidencing a recurrence time of three months or less (early recurrence). At baseline, they underwent pars plana vitrectomy with internal limiting membrane peeling, ending with dexamethasone intravitreal implant injection. Patients were then followed-up monthly, treated with a second injection at the first recurrence, and followed up to the second recurrence. Measurements of best corrected visual acuity, intraocular pressure, and central foveal thickness by spectral-domain optical coherence tomography were performed at each follow-up examination. Results Vitrectomized eyes showed a significant extension of recurrence time of diabetic macular edema, and specifically from 3.4 (3.2–3.7) to 6.5 (5.7–8.2) months after the first injection, and to 7.0 (5.7–8.2) months (p < 0.01) after the second injection (p < 0.01). Conclusions and importance Pars plana vitrectomy with internal limiting membrane peeling seems not to influence functional and anatomical results in eyes under treatment with dexamethasone intravitreal implant injections for diabetic macular edema, but appears to significantly extend the benefit of the drug.

Abstract
PURPOSE INVICOST, a medico-economic analysis, compared costs of managing treatment-naive patients with diabetic macular edema (DME) receiving intravitreal injections (IVIs) of aflibercept (AFL), dexamethasone implant (DXI) or ranibizumab (RAN) over 1 year. METHODS Healthcare resource use and associated costs were estimated using individual patient data from INVICTUS, a prospective, open-label, monocentric study. Healthcare costs comprised direct medical costs such as drug acquisition and administration, consultations and ophthalmological procedures. Costs were assessed from the French National Health Insurance perspective using published national tariffs expressed in 2019 euros. RESULTS Of the 60 treated eyes, 48 had no treatment switch; 14 received AFL, 19 received DXI and 15 received RAN. AFL-treated eyes received an average of 6.5 IVIs, DXI-treated patients received 2 IVIs and RAN-treated received 6.8 IVIs. All treated eyes received an initial prescription for adjunctive ocular medications and 349 follow-up procedures were performed including an average of 3.9 optical coherence tomography and 3.2 retinography procedures per eye. Average total direct cost of per-eye treatment was €4516 (€1128-€8257). Average cost was €5782 for eyes treated with AFL, €2779 with DXI and €5536 with RAN. Drug therapy was the cost driver: €4394 (76%) for AFL, €1915 for DXI (69%) and €4268 (77%) for RAN. CONCLUSION The difference in total treatment cost is largely explained by the significantly lower frequency of IVI and annual cost of therapy with DXI, compared with AFL and RAN. INVICOST is the first study comparing treatment costs with AFL, DXI and RAN in France in current clinical practice.

Abstract
INTRODUCTION Phase III clinical trials of dexamethasone intravitreal implant for diabetic macular oedema (DMO) have reported significant improvements in visual acuity (VA). Studies evaluating the treatment of DMO in routine clinical practice provide data to identify areas that need improvement. This study evaluated 12-month treatment outcomes of dexamethasone implant for DMO in routine clinical practice. METHODS Retrospective data analysis of eyes that started dexamethasone implant for DMO from 1 June 2013 to 30 April 2019 in routine clinical practice tracked in the Fight Retinal Blindness! Registry. RESULTS Of the 4282 eyes (2518 patients) that started DMO treatment in the specified period, 267 (6%) eyes (204 patients) received 454 dexamethasone implant injections. Two-fifths (106 eyes) had received prior treatment for DMO. The mean (95% confidence interval [CI]) VA change at 12 months was 1.8 (- 0.5, 4.2) letters from the mean (standard deviation [SD]) VA of 56.5 (19.8) letters at baseline, with 41% eyes achieving at least 20/40. The mean (95% CI) change in central subfield thickness over 1 year was - 79 (- 104, - 54) µm from a mean (SD) of 459 (120) µm at baseline. Eyes that completed 1 year of follow-up received a median (Q1, Q3) of 2 (1, 2) dexamethasone implants. One-tenth of phakic eyes received cataract surgery while 2% had a pressure response requiring anti-glaucoma medications. CONCLUSIONS One-year treatment outcomes of dexamethasone intravitreal implant for DMO in routine clinical practice were inferior to those in the clinical trials perhaps because of fewer treatments in clinical practice.

Abstract
Intravitreal therapy for diabetic macular edema can, in susceptible patients, increase intraocular pressure (IOP). As uncontrolled IOP can potentially be sight threatening, monitoring is an essential component of patient management. It can be challenging for retina specialists to ensure that monitoring is rigorous enough to detect and resolve any potential problems at the earliest opportunity without it also being overburdensome for patients who have the lowest risk of developing an IOP rise. We have developed dynamic algorithms that: (1) tailor the frequency and extent of monitoring according to individual susceptibility and current IOP and (2) assist retina specialists in deciding when they should consider a referral to a glaucoma specialist. One algorithm is for patients with a relatively low susceptibility to developing an IOP rise (those whose baseline IOP is < 22 mmHg and who do not have a history of IOP events). Depending on their first post-implantation IOP check, the algorithm classifies them as: low risk if IOP remains < 22 mmHg; medium risk if IOP is 22-25 mmHg and any rise from baseline is < 10 mmHg; or high risk if IOP is > 25 mmHg or any rise from baseline is ≥ 10 mmHg. Thereafter, the algorithm guides on the frequency and extent of monitoring required in each of these groups and, if IOP rises or falls during treatment, patients may move up or down the risk groups accordingly. A different algorithm is provided for patients who are more susceptible to developing an IOP rise (those with a baseline IOP of ≥ 22 mmHg or a prior history of an IOP event). These patients need monitoring more closely so this algorithm has only medium- or high-risk classifications. These algorithms update the previous monitoring guidance by Goñi et al. (Goñi et al. in Ophthalmol Ther 5:47-61, 2016).

Abstract
PURPOSE To assess the impact of preoperative intravitreal dexamethasone implant (DexI) on functional and anatomic outcomes in patients with diabetic macular edema (DME) who underwent phacoemulsification cataract surgery. METHODS Prospective and non-comparative study conducted on consecutive DME patients undergoing cataract surgery. DexI was administered 15 days before surgery and in a pro re nata regime after surgery. Main outcome measures were mean change in central retinal thickness (CRT), central subfield thickness (CST), total macular volume (TMV), and central subfield volume (CSV) from baseline to month-12. Secondary outcome was mean change in best corrected visual acuity (BCVA). RESULTS Forty eyes were included in the study. CRT significantly decreased from 410.4 ± 64.8 µm at baseline to 303.2 ± 24.3 µm at month-12, p < 0.0001. Similarly, CST was significantly reduced from 436.4 ± 120.4 µm at baseline to 322.9 ± 54.2 µm at month-12, p < 0.0001. Total macular volume and CSV were significantly reduced from 9.95 ± 1.68 mm3 and 0.38 ± 0.11 mm3 at baseline to 8.49 ± 0.83 mm3 and 0.31 ± 0.05 mm3 at month-12, respectively (p < 0.0001 each, respectively). BCVA significantly improved from 0.26 ± 0.17 Snellen equivalent at baseline to 0.65 ± 0.19 at month-12, p < 0.0001. Mean DexI administered during the study were 2.0 ± 0.3. Neither DME subtype nor previous treatment status had any effect on functional or anatomic outcomes. Regarding safety, one (2.5%) eye developed ocular hypertension, which was successfully controlled with topical hypotensive treatment. CONCLUSIONS DexI was and effective and safe strategy for managing DME in diabetic patients undergoing uneventful cataract surgery.

Abstract
PURPOSE The intravitreal dexamethasone implant (DEX-I) is an alternative to anti-VEGF for the first-line treatment of diabetic macular oedema (DME). However, several questions remain regarding its routine use and its place in certain situations not always specified in current recommendations. A national consensus approach was, therefore, initiated by French retinal experts. METHODS An iterative Delphi consensus approach was used. A steering committee (SC) of seven experts analysed data from the literature to formulate statements divided into five key areas of treatment. These statements were submitted to the independent and anonymous electronic vote of 87 French retina experts among whom 39 expressed their opinion and therefore constituted the voting panel. RESULTS After two rounds of voting, 22 and 7 of 38 statements received a strong consensus and a good consensus, respectively. The consensus level was higher for statements regarding first-line indications and safety of DEX-I compared to those regarding efficacy assessment, reprocessing time or pathophysiological biomarkers. The panellists recommended the preferential use of DEX-I for patients with limited availability for multiple injections, those who needed to undergo cataract surgery or who had a recent cardiovascular history, and as a therapeutic alternative to anti-VEGF in patients with a history of vitrectomy, retinal serous detachment, hyper-reflective points or dry exudates in optical coherence tomography (OCT). However, some statements proposed by SC experts were not validated. CONCLUSION This study provides some key recommendations to clinicians treating diabetic macular oedema, which may be useful when using intravitreal dexamethasone implants in daily practice.

Abstract
PURPOSE Diabetic macular oedema (DMO), a complication of diabetes, causes vision loss and blindness. Corticosteroids are usually used as a second-line treatment. The aim of this study was to analyse the cost-effectiveness of dexamethasone implants compared to cheaper and more frequently applied triamcinolone injections. METHODS Markov-modelling, which incorporated both eyes, was used for economic evaluation. The model consisted of five health states based on visual acuity, illustrating the progression of DMO. A cycle length of five months was chosen for dexamethasone and four months for triamcinolone. Time horizons of two and five years were applied. Transition probabilities and health state utilities were sourced from previous studies. The perspective used in this analysis was the hospital perspective. The health care costs were acquired from Kuopio University Hospital in Finland. RESULTS In this cost-effectiveness analysis, the incremental cost-effectiveness ratio ICER with 3% discount rate was €56 591/QALY for a two-year follow-up and -€1 110 942/QALY for a five-year follow-up. In order to consider dexamethasone as cost-effective over a 2-year time horizon, the WTP needs to be around €55 000/QALY. Over the five-year follow-up, triamcinolone is clearly a dominant treatment. Sensitivity analyses support the cost-effectiveness of dexamethasone over a 2-year time horizon. CONCLUSIONS Since the sensitivity analyses support the results, dexamethasone would be a cost-effective treatment during the first two years with WTP threshold around €55 000/QALY, and triamcinolone would be a convenient treatment after that. This recommendation is in line with the guidelines of EURETINA.

Abstract
Purpose To determine the impact of different baseline clinical characteristics on the improvement in best corrected visual acuity (BCVA) in patients with diabetic macular edema (DME) who underwent the intravitreal dexamethasone implant (DEX) Ozurdex®. Methods This was a single center retrospective study conducted on patients with DME, either naïve or previously treated, who were treated with one or more DEX and had a follow-up of at least 6 months. The main outcome measure was the proportion of DEX achieving an improvement ≥15 letters in BCVA. Results The study analyzed 192 DEX implants administered to 97 eyes (65 patients). Among the 192 DEX analyzed, 57 (29.7%) implants achieved a BCVA improvement ≥15 letters (ETDRS) from baseline, with a mean time for achieving such improvement of 89.2 (39.7) days. Eyes who received an additional DEX and those with a duration of DME < 6 months had a greater probability of achieving a BCVA improvement ≥15 letters (odds-ratio: 2.55, p = 0.0028 and odds-ratio: 1.93, p = 0.0434). The mean (standard deviation) change in BCVA from baseline was 7.5 (14.5) letters, p < 0.0001. The mean change in central macular thickness (CMT) from baseline was -128.0 (151.0) µm, p < 0.0001. The mean number of DEX implanted was 1.9 (0.8). Four (2.1%) DEX experienced an intraocular pressure increased ≥10 mm Hg; all the cases were successfully managed with topical antiglaucoma medication. Conclusion The results of this study confirmed previous evidence suggesting that DEX is effective for improving BCVA and CMT in patients with DME.

Abstract
AIM To investigate the safety and efficacy of intravitreal dexamethasone implants (Ozurdex®/DEX) in patients with diabetic macular edema (DME) either naïve or non-naïve to anti-VEGF therapies who switched to DEX implant independent of response to anti-vascular endothelial growth factors (anti-VEGFs). METHODS This was an audit retrospective review of medical records of patients with DME who switched to the DEX intravitreal implant. Patients were divided into 2 groups: patients naïve to antiangiogenic therapy and patients who were previously treated with anti-VEGFs. Data regarding demographics, changes in mean best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) was collected over 6mo. The demographic data mean changes in BCVA, CMT, and IOP were compared. Six-month follow-up data of 47 patients (57 eyes), who either switched to DEX implant irrespective of response to previous treatments or were treatment naïve before receiving DEX implant, was collected. RESULTS Improvement in mean BCVA was observed from 1-4mo after injection with a decreased effect at month 6 as expected, with better outcomes in naïve compared to non-naïve patients. A statistically relevant decrease in mean CMT was observed during the follow-up period. An increase in mean IOP was observed in the first 2mo after DEX therapy. The mean number of injections of the overall population during the 6mo was 1.3. A subgroup analysis showed no relevant difference between phakic versus pseudophakic patients relative to measured outcomes. There was no cataract progression during the follow-up period and no adverse events reported. CONCLUSION This real-life setting study shows that intravitreal DEX implant is effective and safe. The timings of greater therapeutic impact are concordant with previous studies and suggest that earlier treatment with corticosteroids may have an additional benefit in naïve patients.

Comparison of Intravitreal Dexamethasone Implant and Ranibizumab in Vitrectomized Eyes with Diabetic Macular Edema. J Ophthalmol 2021; 2021:8882539. [PMID: 34540287 PMCID: PMC8448602 DOI: 10.1155/2021/8882539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 08/26/2021] [Indexed: 11/17/2022] Open
Abstract
Purpose This retrospective study aimed to compare the efficacy of intravitreal ranibizumab (IVR) and intravitreal dexamethasone implant (IDI) for pseudophakic vitrectomized eyes with diabetic macular edema (DME) in a single institution. Methods Pseudophakic vitrectomized eyes with treatment-naïve center-involved DME were enrolled, with one eye in each patient. They were divided into two groups: one group receiving IDI every 3 to 4 months and another group receiving IVR using 3 monthly plus treat-and-extend injections, all with monthly follow-up for 6 months. Switch of intravitreal drugs or deferred macular laser was not allowed. Primary outcome measures included change in central foveal thickness (CFT) in 1 mm by spectral-domain optical coherence tomography and best-corrected visual acuity (BCVA) at Month 6. Results Twenty-two eyes were included in the IDI group and 26 eyes in the IVR group. The baseline demographics, glycosylated hemoglobin level, intraocular pressure (IOP), BCVA, and CFT did not significantly differ (p > 0.05). Compared to baseline data, CFT decreased and BCVA improved significantly after either IDI or IVR at Month 6 (p < 0.05). Significantly better mean final BCVA (0.38 logMAR vs. 0.62 logMAR, p=0.04), more mean visual gain (−0.30 logMAR vs. −0.15 logMAR, p=0.02), lower mean final CFT (310.9 μm vs. 384.2 μm, p=0.04), and larger mean CFT decrease (−150.0 μm vs. −60.1 μm, p=0.03) were found in the IDI group compared to those in the IVR group. A smaller mean treatment number (2.6 vs. 5.6, p < 0.001) and higher rate of postinjection ocular hypertension requiring topical hypotensive agent therapy (27.3% vs. 0%, p=0.0002) were demonstrated in the IDI group than those in the IVR group. Conclusion We concluded that IDI and IVR can both effectively treat vitrectomized eyes with DME. Dexamethasone implants had significantly better visual/anatomical improvement, smaller treatment number, and higher rate of elevated IOP after injection than IVR in pseudophakic vitrectomized eyes with DME in a 6-month period.

Abstract
Introduction to evaluate the effect of dexamethasone biodegradable implant (DEX-I), on intraocular pressure (IOP), to determine the incidence of secondary ocular hypertension (OHT) and to analyze the IOP changes as per the treatment indication in Zambian cohort. Methods retrospective consecutive case series of patients receiving one DEX-I between January 2016 and September 2018 with a minimum follow-up of four months in a tertiary care centre in Zambia. The IOP was recorded before the injection and at 1st week, 1st, 2nd, 3rd and 4th month after the injection. Ocular hypertension was defined as IOP ≥ 21 mmHg or an increase of ≥ 10 mmHg from baseline. Results the effects of 122 injections given to ninety - nine patients (65 male: 65%; mean age 57.3) were included. The main indications for treatment were diabetic macular edema (DME, 52%), retinal vein occlusion (18%), post-surgical macular edema (18%) and non-infectious posterior uveitis (10%). Mean IOP before the injection was was 14.7mmHg and at 1st week, 1st, 2nd, 3rd and 4th months after the injection it was 14.4 (p=0.08), 16.1 (p=0.01), 17.5 (p<0.001), 15.7 (p=0.006) and 14.9 (p=0.06) mmHg, respectively. The incidence of secondary OHT was 30.32% in this cohort. Peak incidence of OHT was between 1 - 2 months, with majority of cases in DME group (75%) and 43% diabetic eyes followed by 23% non-infectious posterior uveitis cases developing OHT post injection. OHT was well managed with anti-glaucoma medications only. Conclusion DEX-I showed a good pressure tolerance in this cohort. Secondary ocular hypertension developed in one-third of patients receiving injection which was transient and successfully managed with topical anti-glaucoma medications only. Diabetic eyes are more prone to develop ocular hypertension and therefore needs close monitoring following injection.

Abstract
Diabetic macular edema (DME) is a very important and well-known cause of visual loss in diabetics. Blood–retina barrier disruption and consequent intraretinal fluid accumulation may lead to retinal thickening at the posterior pole namely DME. Even though it is not clearly understood, current evidence suggests that chronic low-grade inflammation characterized with various cytokines has a major role in the occurrence of DME. Clinical trials are continuously shaping our treatment approaches for the eyes with DME. Today, vascular endothelial growth factor (VEGF) inhibitor and steroid administrations are the main alternatives in DME treatment. Dexamethasone (DEX) implant (Ozurdex®; Allergan, Inc., Irvine, CA, United States) was approved by the United States Food & Drug Administration in 2014 for DME treatment. The implant is made up of a biodegradable solid copolymer that is broken down by releasing its active ingredient into the vitreous cavity over time. Biphasic release feature of this sustained-release drug delivery system ensures its efficacy for up to 6 mo with an acceptable and manageable safety profile. DEX implant provides a favorable anatomical and functional outcome in DME as shown in several randomized-controlled studies but has a relatively higher ocular side-effect profile such as increased risk of cataract formation and raised intraocular pressure when compared to the gold standard anti-VEGF agents. Thus, DEX implant becomes the second-line treatment option demonstrating inadequate clinical response to anti-VEGF therapy. However, it can be preferred as the first-line treatment in vitrectomized and pseudophakic eyes. Even in some selected conditions DEX implant is favored over anti-VEGF agents where the use of VEGF-inhibitors is either inappropriate or contraindicated such as the patients with a recent history of a major cardiovascular or cerebrovascular event, pregnancy and noncompliant to frequent visits. This mini-review briefly overviews the efficacy, safety profile and complications of DEX implant and summarizes the outcome of DEX implant administration in major clinical studies on DME treatment.

Abstract
PURPOSE To analyse the morpho-functional outcomes of dexamethasone intravitreal implant (Ozurdex) injected after lens surgery in diabetic patients with coexisting cataract and macular oedema. METHODS This is a non-randomized, perspective, single-group study on 17 eyes with a diagnosis of cataract and early and advanced diabetic macular oedema. All eyes underwent combined phacoemulsification and Ozurdex injection at the end of surgery and morpho-functional outcomes were analysed in 3 months follow-up. RESULTS Foveal thickness decreased significantly from 349.6 ± 19.8 (95% CI) at baseline to 310.7 ± 17.5 (95% CI) 90 days after surgery (p < 0.01).Mean BCVA (LogMAR) improved significantly from 0.38 ± 0.08 (95% CI) at baseline to 0.15 ± 0.06 (95% CI) after 90 days (p < 0.01). Any ocular or systemic complications were observed during follow-up. CONCLUSIONS Dexamethasone intravitreal implant combined with phacoemulsification may be safe and effective to improve morpho-functional outcomes in diabetic patients with coexisting cataract and macular oedema.

Abstract
PURPOSE To evaluate long term outcomes of patients presenting with diabetic macular edema (DME) or edema secondary to a retinal vein occlusion (RVO). METHODS This is a real world, retrospective, single-center study of 65 eyes of 47 patients treated for DME and 33 eyes of 33 patients with macular edema secondary to RVO between July 2012 and October 2018. The patients treated were treatment-naive and were followed for at least one year. We collected data such as visual acuity, central macular thickness, intravitreal injections (number/year, injection schedule, number of switches), number of visits and cases of vision loss. RESULTS DME: the mean age at inclusion was 65.9years with 60.4% women, and the mean follow-up was 28.5months. The mean gain in visual acuity after 1year of follow-up was 6.4 ETDRS letters for patients treated with anti-VEGF and 2.6 letters for patients treated with dexamethasone. The average number of intravitreal injections of anti-VEGF was 5.6/year, compared to 2.9/year for dexamethasone. Fourteen patients initially treated with anti-VEGF were switched to dexamethasone. RVO: the mean age at inclusion was 68.8years with 54.5% women and a mean follow-up of 31.1months. The mean gain in visual acuity after 1year of follow-up was 26.7 ETDRS letters for patients treated with anti-VEGF and 7.0 letters for patients treated with dexamethasone. The average number of intravitreal injections of anti-VEGF was 5.8/year, compared to 2.4/year for dexamethasone. Five patients initially treated with anti-VEGF were switched to dexamethasone in the first year of follow-up. CONCLUSION In this real-life retrospective study, we found good anatomical and functional results similar to those reported in other studies, remaining stable over time, for patients with DME or macular edema secondary to RVO.

Abstract
PURPOSE To assess the efficacy and safety of dexamethasone 0.7 mg implants (DEX-I) in patients with diabetic macular edema (DME) either naïve to therapy or refractory to anti-VEGF treatment, in a single-center, real-world setting. METHODS Patients diagnosed with DME and treated with DEX-I were retrospectively enrolled in the study and split in two groups: naïve (Group 1, n = 64) and refractory (Group 2, n = 64) to treatment. Patients were evaluated at baseline, at 1 month, and every 3 months after each DEX-I implant. Main outcome measures were change in best-corrected visual acuity (BCVA) and central macular thickness (CMT) from baseline to follow-up visits. RESULTS Significant improvements in BCVA were observed in treatment-naïve patients at 6 months following the first and second DEX-I injection (p = 0.0023 and p = 0.0063, respectively), with significant reductions in mean CMT at 6 months after all DEX implants. In treatment-refractory patients, mean CMT was significantly reduced from baseline to 6 months (p < 0.05) after all DEX-I injections, although no changes were observed in BCVA. CONCLUSIONS DEX-I improved visual acuity and macular edema mostly in treatment-naïve patients, suggesting DEX-I may be a viable first-line treatment option in DME.

Outcome of Single Dexamethasone Implant Injection in the Treatment of Persistent Diabetic Macular Edema After Anti-VEGF Treatment: Real-Life Data from a Tertiary Hospital in Jordan. Clin Ophthalmol 2021; 15:1285-1291.

Abstract
Purpose To analyze the real-life clinical outcome of a single dexamethasone implant (DEX) injection in the treatment of persistent diabetic macular edema (DME) after anti-vascular endothelial growth factor (anti-VEGF) agents in a sample of the Jordanian population. Methods An observational case study design that involved a retrospective chart review analysis in a tertiary hospital in Amman, Jordan. Patients who showed persistent DME after receiving at least six doses of anti-VEGF agents for DME treatment were included. Results The study population consisted of 72 participants (29 females, 43 males) having an average age of 66 years. All patients had best-corrected visual acuity (BCVA) less than 0.7 (6/9) and SD-OCT documented center-involved DME. The study results showed that the average baseline BCVA improved from 0.205±0.1 before DEX injection to 0.358±0.1 at 3 months post-injection (p<0.0001). The central mean thickness (CMT) showed significant improvement also (539.347±132.402 to 379.041±99.430, p<0.0001). There was a mean of 3 mmHg increase in intraocular pressure at 3 months post-injection (p<0.0001), however, only 4% of patients required medical treatment. Other inflammatory biomarkers in OCT, such as intraretinal hyper-reflective dots (HRD), showed significant improvement also (23.67±16 to 14.83±13, p<0.0001). No other significant safety concerns were noticed. Conclusion A single DEX injection showed significant clinical and anatomical improvement in DME cases that are persistent after anti-VEGF treatment in our sample, with an excellent safety profile. In case of supply shortage of intravitreal injections, which occurs frequently at our center, a single DEX injection may be utilized as an effective DME therapy. Further research is mandated to identify clinical response in a larger sample and more frequent injections.

Abstract
BACKGROUND Dexamethasone (DEX) implant has been shown to improve visual and anatomic function in patients with diabetic macular edema (DME). The purpose of this study was to investigate the efficacy and safety of DEX implant between refractory and naive eyes with DME. METHODS We retrospectively reviewed data from pseudophakic patients with center-involved DME who received DEX implant (1 + as needed retreatment) from May 2015 to May 2017. Baseline clinical characteristics, changes in best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were analyzed and compared between the two groups. Adverse events were recorded. RESULTS Thirty-four eyes of 31 patients refractory to anti-vascular endothelial growth factor agents and 41 eyes of 38 treatment-naive patients were reviewed. Baseline characteristics were comparable between the two groups (p > 0.05). In the refractory eyes, significant improvements in both BCVA and CFT were observed at 1 month post DEX implant and sustained throughout 6 months. Mean change from baseline in BCVA at 6 months was -0.17 ± 0.35 logMAR (7.29 ± 16.22 letters) and 155.44 ± 112.67 μm in CFT. Similar trends of improvement were seen in treatment-naive eyes; however, the visual improvement (-0.30 ± 0.29 logMAR [16.42 ± 14.38 letters]) was significantly better than the refractory group, with significantly less injections (1.54 ± 0.49 versus 1.82 ± 0.38, p = 0.007). Between-group changes in CFT were comparable. No serious ocular complications occurred, and about a quarter of the patients had elevated intraocular pressures that were manageable with topical medications. CONCLUSION To our knowledge, this was the first study comparing DEX implant between treatment-naive and refractory Asian patients with DME. Intravitreal DEX implant can effectively treat refractory and treatment-naive patients with DME. In addition, superior visual outcomes were observed in the naive group comparing to the refractory group following DEX implant treatment in Taiwanese pseudophakic eyes with DME.

Abstract
PURPOSE To evaluate the real-life efficacy and safety of the intravitreal dexamethasone implant in uveitis. METHODS This retrospective observational multicentric study included 152 eyes treated exclusively by 358 dexamethasone implant injections. The main outcome measures included change in the best-corrected visual acuity, central macular thickness, and vitreous haze score. RESULTS Patients were treated with dexamethasone implant for macular edema (51.3%), vitritis with macular edema (40.1%), vitritis (5.3%), and other causes (3.3%). The mean duration of follow-up was 19.0 months. The mean gain in best-corrected visual acuity during follow-up was +12.1 letters. An improvement in best-corrected visual acuity ≥5, 10, and 15 letters was found in 64.5, 50.7, and 35.5% of cases, respectively. 59.7% of eyes with macular edema at baseline were found to be anatomical responders. Vitritis resolution (vitreous haze = 0+) was obtained in 81.4% of cases. Ocular hypertension (intraocular pressure ≥25 mmHg and/or gain ≥10 mmHg from baseline) occurred in 28.3% of patients. No filtering surgery/laser therapy was required. A total of 40.2% of phakic subjects underwent cataract surgery on average 11.2 months after the first injection. CONCLUSION This study confirms the efficacy and safety of the dexamethasone implant in noninfectious uveitis. Cataract and ocular hypertension were not uncommon but easily manageable.

Abstract
To analyze functional and anatomical response patterns to dexamethasone (DEX) implant in diabetic macular edema (DME), to describe proportion of responders and non-responders, and to propose a new DME grading system. Retrospective, multicenter, observational cohort study. Naïve and non-naïve DME patients were treated with DEX, with visual acuity (VA) ≥ 0.2 logMAR and central subfield thickness (CST) of ≥ 300 µm. Functional and anatomical responses were graded after 2 and 4 months, and categorized as early and stable improvement, early and progressive improvement, pendular response, delayed improvement, and persistent non-response. 417 eyes were included (175 treatment naïve eyes). Compared to non-naïve eyes, naïve eyes showed a very good functional response (VA gain ≥ 10 letters) more frequently after 2 and 4 months (56% and 57% [naïve] vs. 33% and 28% [non-naïve], p < 0.001). A VA gain < 5 letters (non-response) after 2 and 4 months was seen in 18% and 16% of naïve eyes, and in 49% and 53% of non-naïve eyes (p < 0.001). A lack of anatomical response was rare in both groups, but more frequently in non-naïve eyes (12% vs. 4%, p = 0.003). Functionally and anatomically, naïve eyes showed most frequently an early and stable improvement (functionally: 77/175 44%; anatomically: 123/175 eyes, 70%). Most non-naïve eyes experienced no significant improvement functionally (97/242 eyes, 40%), despite a mostly early and stable improvement anatomical response pattern (102/242 eyes, 42%). Functional but not anatomical response patterns were influenced by baseline VA. Naïve and non-naïve eyes show different functional and anatomical response patterns to DEX implant. Functional non-responders are rare in naïve eyes, whereas anatomical non-response is unusual in both groups.

Abstract
We conducted a meta-analysis of real-world studies on the 0.19 mg Fluocinolone Acetonide (FAc) intravitreal implant for chronic diabetic macular oedema (DMO), comparing these findings with the Fluocinolone Acetonide for Diabetic Macular Edema (FAME) study. The primary outcome was mean change of best corrected visual acuity (BCVA) at 24 months. Secondary outcomes were 36-month mean BCVA, mean central macular thickness (CMT) change, rates of eyes receiving supplementary intravitreal therapy, cataract surgery, intraocular pressure (IOP)-lowering drops and glaucoma surgery. Mean differences (MDs) with 95% confidence intervals (CIs) were calculated. Nine real-world studies were included. The FAc implant yielded a significantly improved BCVA at 24 and 36 months (24-month MD = 4.52; 95% CI 2.56–6.48; 36-month MD = 8.10; 95% CI 6.34–9.86). These findings were comparable with the FAME study. The FAc implant yielded significantly reduced 24- and 36-month CMT. Pooled proportions of cataract surgery, IOP-lowering drops and glaucoma surgery were 39%, 27% and 3%, respectively, all lower than the FAME study. Pooled estimate of supplementary intravitreal therapy was 39%, higher than the 15.2% of the FAME study. This meta-analysis of real-world studies confirms favorable visual and anatomical outcomes following FAc insert for chronic DMO. In real-life studies more than one third of patients received supplementary intravitreal therapy, an issue that needs to be further explored.

Intravitreal Therapy for Diabetic Macular Edema: An Update. J Ophthalmol 2021; 2021:6654168. [PMID: 33688431 PMCID: PMC7925023 DOI: 10.1155/2021/6654168] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Revised: 02/11/2021] [Accepted: 02/16/2021] [Indexed: 02/07/2023] Open
Abstract
Diabetic macular edema (DME) represents a prevalent and disabling eye condition. Despite that DME represents a sight-threatening condition, it is also among the most accessible to treatment. Many different treatment options including photocoagulation, intravitreal medical treatment (either vascular endothelial growth factor inhibitors or corticosteroids therapies), and surgical removal are currently available. Although laser has been considered as the gold standard for many years, over the past several years vascular endothelial growth factor inhibitors (anti-VEGFs) have become first-line therapy. However, many patients do not adequately respond to them. With the development of sustained-release corticosteroid devices, steroids have gained a presence in the management of the DME. We review and update the role of anti-VEGF and intravitreal sustained-release corticosteroid management of DME. According to the currently available scientific evidence, the choice of one anti-VEGF over another critically depends on the baseline best-corrected visual acuity (BCVA). While aflibercept may be the drug of choice in low baseline BCVA, the three anti-VEGFs (bevacizumab, ranibizumab, and aflibercept) provided similar functional outcomes when the baseline BCVA was higher. DEX implants are a valuable option for treating DME, although they are usually seen as a second choice, particularly in those eyes that have an insufficient response to anti-VEGF. The new evidence suggested that, in eyes that did not adequately respond to anti-VEGF, switching to a DEX implant at the time to 3 monthly anti-VEGF injections provided better functional outcomes.

Abstract
PURPOSE To report clinical outcomes of two different timings of intravitreal dexamethasone (DEX) implant administration for prevention of diabetic macular oedema (DME) worsening following cataract surgery. METHODS This multicentre, retrospective study included patients with DME who received an intravitreal DEX implant 1 month before cataract surgery, 'precataract DEX' group, or at the time of cataract surgery, 'concomitant treatments' group. Inclusion criteria were a follow-up ≥3 months and ophthalmological examination with optical coherence tomography (OCT) imaging at baseline (cataract surgery) and throughout follow-up. Anatomical improvement was considered to be a decrease in OCT central subfield (CSF) thickness ≥20% compared to baseline. The primary outcomes were anatomical and functional results at 3 months. RESULTS Two hundred twenty-one patients were included: 136 in the 'precataract DEX' group and 85 in the 'concomitant treatments' group. At 3 months, a reduction of CSF thickness ≥ 20% was found in 7.3% of eyes in the 'precataract DEX group' and in 83.7% of eyes in the 'concomitant treatments' group (p < 0.001), with mean CSF thickness lower in the latter group (371 ± 52 µm versus 325 ± 57 µm, p < 0.001). At 3 months, mean best-corrected visual acuity had improved from baseline in both groups (p < 0.001), with no difference between groups (p = 0. 20). No serious systemic adverse events were reported. CONCLUSION Both approaches prevented a worsening of DME, showing a comparable visual outcome. Dexamethasone (DEX) implant given at the same time as cataract surgery provided a better anatomical outcome.

Saudi Arabia Guidelines for diabetic macular edema: A consensus of the Saudi Retina Group. Saudi Med J 2021; 42:131-145.

Abstract
Diabetes mellitus (DM) and its complications are major public health burdens in Saudi Arabia. The prevalence of diabetic retinopathy (DR) is 19.7% and the prevalence of diabetic macular edema (DME) is 5.7% in Saudi Arabia. Diabetic macular edema is a vision-threatening complication of DR and a major cause of vision loss worldwide. Ocular treatments include retinal laser photocoagulation, anti-vascular endothelial growth factor (anti-VEGF) agents, intravitreal corticosteroids, and vitreoretinal surgery when necessary. The present consensus was developed as a part of the Saudi Retina Group's efforts to generate Saudi guidelines and consensus for the management of DME, including recommendations for its diagnosis, treatment, and best practice. The experts' panel stipulates that the treatment algorithm should be categorized according to the presence of central macula involvement. In patients with no central macular involvement, laser photocoagulation is recommended as the first-line option. Patients with central macular involvement and no recent history of cardiovascular (CVS) or cerebrovascular disorders can be offered anti-VEGF agents as the first-line option. In the case of non-responders (defined as an improvement of <20% in optical coherence tomography or a gain of fewer than 5 letters in vision), switching to another anti-VEGF agent or steroids should be considered after 3 injections. Within the class of steroids, dexamethasone implants are recommended as the first choice. In patients with a recent history of CVS events, the use of anti-VEGF agents is not recommended, regardless of their lens status. The experts' panel recommends that a future study be conducted to provide a cut-off point for early switching to steroid implants in pseudo-phakic eyes.

Abstract
Purpose This meta-analysis aims to summarize 12-month best-corrected visual acuity (BCVA) outcomes in response to anti-vascular endothelial growth factor (VEGF) therapy and dexamethasone implant for the treatment of diabetic macular edema (DME) and to identify factors affecting treatment response using evidence generated from meta-regression. Methods A systematic review of electronic databases was conducted to identify randomized controlled trials (RCTs) and real-life/observational studies that reported 12-month changes in BCVA in patients with DME on anti-VEGF or dexamethasone implant treatment in monotherapy. Study factors that were analyzed are baseline patient characteristics, study type, drug employed, number of injections and 12-month change in BCVA. Data were pooled in a random-effects meta-analysis with BCVA change as the main outcome. Meta-regression was conducted to assess the impact of multiple covariates. Results One-hundred-five heterogeneous study populations (45,032 eyes) were identified and included in the analysis. The use of anti-VEGFs and dexamethasone implant induced an overall increase of +8.13 ETDRS letters in BCVA at 12 months of follow-up. Meta-regression provided evidence that mean BCVA change using anti-VEGFs was not statistically higher for RCTs (p=0.35) compared to observational studies. Dexamethasone implant showed a trend for better results in observational studies over RCTs. Populations following a fixed aflibercept regimen performed better than those following a reactive treatment regimen. Mean BCVA gain was higher in younger populations (p<0.001), with lower baseline BCVA (p<0.0001) and longer diabetes duration (p<0.0001), receiving a higher number of injections (p<0.0001). Conclusion Intravitreal therapy with anti-VEGFs or dexamethasone implant produces a significant improvement in BCVA at 12 months in patients with DME. Meta-regression identified the modifiable covariates that can be targeted in order to maximize functional results.

Abstract
AIMS To evaluate the efficacy and safety of intravitreal dexamethasone implant (DEX-implant) for diabetic macular edema (DME) in real-life practice with an extended follow-up for up to 5 year. METHODS This multicentric retrospective study reviewed 227 eyes of 152 patients with DME treated by DEX-implant. Main outcome measures included changes in best corrected visual acuity (BCVA), central macular thickness (CMT), time to retreatment and incidence of adverse effects. RESULTS The mean number of DEX-implant received by patients was 2.6 (± 2.2) with a mean (SD) follow-up of 20.1 (± 15.8) months, median [IQR] 15.8 [7.4-30.1]. The mean time of retreatment was 6.9 months. The mean maximal BCVA gain during follow-up was 12.3 (± 12.7) letters. A gain of ≥ 5, ≥ 10 and ≥ 15 letters from baseline BCVA was obtained for 71.8%, 48.9% and 34.8% of eyes, respectively. A total of 62.6% of eyes presented a significant anatomical response (decrease of CMT ≥ 20%), and DME was resolved (absence of cystoid macular spaces on OCT) in 37% of cases at the end of the follow-up. A transient increase in intraocular pressure ≥ 25 mmHg occurred in 14.1% of eyes, and cataract surgery was performed for 49.1% of the phakic eyes during the follow-up. Four eyes developed a proliferative diabetic retinopathy. CONCLUSION This large cohort study showed favorable long-term outcomes when using DEX-implant, which provides substantial long-term benefits in the treatment of DME in real life.

Abstract
Background To identify different response patterns to intravitreal dexamethasone implants (IDI) in naïve and previously treated (PT) diabetic macular edema (DME) eyes in a real-life setting. Methods 342 IDI injections (203 DME eyes) were included. Number of IDI injections, percentage (%) of eyes with 1, 2, 3 and ≥ 4 injections, time to reinjections, visual acuity (VA), intraocular pressure (IOP) and central retinal thickness (CRT) were evaluated for naïve and PT DME eyes over 24 months. Results Mean number of injections was significantly lower in naïve vs PT DME eyes (1.40 ± 0.9 vs 1.82 ± 0.9, p < 0.001). The percentage of eyes receiving 1 injection was significantly higher in naïve vs PT DME eyes (76.1 vs 47.7), (p < 0.001). However, it was significantly lower for 2 (16.4 vs 29.4), or 3 injections (1.4 vs 17.6) (both p < 0.001), with no differences in eyes receiving ≥4 injections (5.9 vs 5.1 respectively, p = 0.80). Mean time to reinjection was not significantly different between both groups for the second, third and fourth injection (9.6 ± 4.0 vs 10.0 ± 5.5, p = 0.75, 13.2 ± 4.0 vs 16.0 ± 3.5, p = 0.21 and 21.7 ± 3.8 vs 19.7 ± 5.8, p = 0.55). VA scores were consistently better in naïve vs PT DME eyes at all studied timepoints, with no significant differences in CRT reduction or adverse effect rates. Conclusion Naïve DME eyes received lower number of IDI injections and showed better VA levels than PT DME eyes for 24 months in a real-world setting. This data supports the IDI use in early DME stages and provide further evidence of better IDI response when used as first-line therapy.

[PMID: 32970316 PMCID: PMC7547947 DOI: 10.1007/s12325-020-01506-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Accepted: 09/14/2020] [Indexed: 01/30/2023]
Abstract
Introduction Cataract surgery can be associated with vision-threatening complications in patients with diabetes. This study aimed to assess the functional and anatomic outcomes of the intravitreal dexamethasone (DEX) implant, administered at the time as cataract surgery, in patients with diabetic retinopathy and diabetic macular edema (DME). Methods This was a retrospective, observational, and single-center study. The primary endpoint was the mean change in central macular thickness (CMT) from baseline to month 1. Secondary endpoints included mean change in best corrected visual acuity (BCVA) from baseline to month 1 and 3, mean change in CMT from baseline to month 3, the photopic negative response (PhNR) and the b wave of flash full-field electroretinogram from baseline to month 1, and the incidence of adverse events. Results Twenty-four eyes of 21 patients were included in the study. The mean (range) age of patients was 69 (63–87) years and 13 (61.9%) were men. Mean (standard deviation) CMT significantly decreased from 447 (134) µm at baseline to 341 (134) µm at month 1 (mean difference − 106 ± 134 µm, 95% CI − 183.9 to − 28.1 µm; p = 0.0087). BCVA significantly improved from 46 (20) ETDRS letters at baseline to 59 (22) ETDRS letters at month 1 (mean difference 13 ± 21 letters, 95% CI 0.8–25.2 letters; p = 0.0375). Regarding electrophysiology, there was a statistically significant reduction in mean PhNR from 5.24 (1.67) µV at baseline to 3.73 (1.19) µV at month 1 (mean difference − 1.51 ± 0.42 µV, 95% CI − 2.4 to − 0.7 µV, p = 0.0008); whereas b wave amplitude did not change (12.69 ± 6.89 µV at baseline versus 12.29 ± 6.30 µV at month 1; p = 0.8347). Four (16.7%) eyes developed ocular hypertension over the course of follow-up, which was successfully controlled with topical hypotensive medication. Conclusion Perioperative DEX implant significantly improved both anatomic and functional outcomes in patients with DME who underwent cataract surgery.

Abstract
Purpose To evaluate the initial ten years of results from the intravitreal dexamethasone implant (DEX) in patients treated for retinal vein occlusion (RVO), diabetic macular edema (DME) or uveitis. Methods Retrospective chart review of patients receiving DEX since its FDA approval. Best-corrected visual acuity (BCVA), central macular thickness (CMT) on optical coherence tomography, intraocular pressure and cataract status were collected. Baseline data were collected from the initial DEX and post-treatment data at the visit at least four weeks after the last DEX. Results In total, 315 eyes received 1216 DEX over 63.9±4.6 weeks. In the branch RVO (n=90), central RVO (n=59) and DME (n=62) cohorts, BCVA improved significantly (p<0.05). The uveitis (n=154) cohort did not have a significant change in BCVA, 0.62±0.04 to 0.61±0.04 logMAR (p=0.34). Younger patients, vitrectomized eyes, and eyes without a history of glaucoma were associated with significantly better BCVA outcomes in the uveitis cohort (p<0.05). Overall, CMT decreased significantly from 376.6±6.8 to 322.7±5.0 µm (p<0.05). Intraocular pressure increased significantly (p<0.001) and the percentage of patients requiring anti-glaucoma medications increased from 33.0% to 67.6%. Of phakic eyes, 58.8% (n=63) had cataract progression or underwent surgery with those who underwent surgery experiencing a significant improvement in BCVA (p<0.05). Conclusion Repeated DEX over extended follow-up offers significant anatomic benefits to all cohorts. Visual benefits are only seen in RVO, DME and select uveitis demographics.

Intravitreal dexamethasone implant in naïve and previously treated patients with diabetic macular edema: a retrospective study. Int J Ophthalmol 2020; 13:1597-1605. [PMID: 33078111 DOI: 10.18240/ijo.2020.10.14] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Accepted: 05/13/2020] [Indexed: 11/23/2022] Open
Abstract
AIM To assess the effect of the intravitreal dexamethasone implant (DEX) Ozurdex on the best corrected visual acuity (BCVA) and central retinal thickness (CRT) in patients with diabetic macular edema (DME). METHODS Totally 43 eyes (24 naïve and 19 previously treated) were included in the study. Retrospective and single-center study involved patients with a clinical diagnosed of DME, who received treatment with DEX implant and had a follow-up of at least 12mo. Primary endpoints included changes in BCVA and CRT. RESULTS At month 12, mean improvement in BCVA from baseline was 20.4±20.8 letters and 6.8±6.9 letters in naïve and previously treated patients, respectively (P=0.0132). The naïve patients achieved the BCVA improvement significantly faster (2.4±1.5mo) than the previously treated ones (3.5±2.4mo, P=0.0298; Mann-Whitney test). The proportion of eyes gaining ≥15 letters was 54.2% and 21.1% in the non-previously treated and previously treated groups, respectively (P=0.0293). CRT was significantly reduced from 484.0±119.8 and 487.5±159.9 µm to 272.0±39.2 and 233.5±65.7 µm in the naïve and previously treated patients, respectively; P<0.0001 each, respectively. The presence of subretinal fluid was significantly associated with the proportion of patients achieving a BCVA improvement ≥5 letters [HR (95%CI), 1.23 (1.04 to 1.45), P=0.0145]; ≥10 letters [HR (95%CI), 1.75 (1.10 to 2.77), P=0.0182]; and ≥15 letters [HR (95% CI), 2.04 (1.03 to 4.02), P=0.0407]. Naïve patients received less DEX implants throughout the study than the previously treated ones (1.8±0.6 vs 2.3±0.6, P=0.0172, respectively). Totally 9 patients (20.9%) have developed ocular hypertension, which was successfully controlled with topical hypotensive drugs. Of the 23 phakic eyes at baseline, 5 eyes (21.7%) either had new onset lens opacity or progression of an existing opacity during the study follow-up. Four of them (2 in the naïve group and 2 in the previously treated one) required cataract surgery at months 4, 6, 6, and 6, respectively. CONCLUSION The results obtained in this study may support the early use of DEX Ozurdex as first line therapy in naïve patients.

Postmarketing safety surveillance of dexamethasone intravitreal implant in the treatment of visual impairment due to diabetic macular edema in India. BMC Ophthalmol 2020; 20:405. [PMID: 33036583 PMCID: PMC7545916 DOI: 10.1186/s12886-020-01630-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Accepted: 08/31/2020] [Indexed: 11/24/2022] Open
Abstract
Background Diabetic macular edema (DME) is the most common cause of vision loss in diabetic patients. As India has the second largest population of diabetic patients worldwide, availability of various treatment options for DME is essential. This postmarketing surveillance study was conducted to fulfill a commitment to the Regulatory Authority of India to examine the safety of dexamethasone intravitreal (DEX) implant over 1 year in Indian patients with DME receiving ≥1 DEX implant for DME-related visual impairment in clinical practice. Methods This observational, prospective, non-interventional study enrolled patients aged ≥18 years scheduled to receive DEX implant for DME-related visual impairment. Baseline demographics, medical history, date of last DEX implant injection, detailed information about adverse events (AEs), AEs of special interest (AESIs), serious AEs (SAEs), and adverse drug reactions (ADRs) reported during postinjection visits and investigator telephone calls were collected. Primary outcome measures were treatment-emergent AE (TEAE), AESI, SAE, and ADR occurrences. Results Of the enrolled patients (19 sites throughout India; n = 250), 84 had received DEX implant previously; mean (standard deviation; SD) duration between prior and study entry dose was 199.4 (156.0) days, and 91 (36.4%) had ≥1 prior ophthalmic condition. Over a mean of 182.6 (88.6) follow-up days (min–max: 0–364 days), 22 TEAEs were reported by 7 (2.8%) patients, 6 of whom had previously received DEX. AESIs of increased IOP (n = 3, 6 events) and glaucoma (n = 1, 1 event) were considered non-serious, of mild/moderate severity, and related to DEX treatment. Eyelid ptosis was reported in 1 patient (1 event). Nonocular AEs included cardiac AEs (n = 3, 4 events), pyrexia (n = 1, 2 events), and dyspnea (n = 1, 2 events). Three (1.2%) patients had 12 serious AEs; most were cardiac disorders; all were unrelated to DEX treatment. Two (0.8%) deaths were considered unrelated to treatment. Conclusions Based on voluntary reporting of adverse events in this surveillance study, DEX implant for treatment of DME-related visual impairment in the Indian population demonstrated a favorable safety profile with few treatment-related TEAEs (none were considered serious) during the 1-year follow-up. These data supplement previous findings and confirm the safety of DEX implant in this population during usual clinical practice.

A Real-World Study of Dexamethasone Implant in Treatment-Naïve Patients with Diabetic Macular Edema: Efficacy and Correlation Between Inflammatory Biomarkers and Treatment Outcome. Clin Ophthalmol 2020; 14:2657-2665. [PMID: 32982158 PMCID: PMC7501979 DOI: 10.2147/opth.s257775] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Accepted: 08/07/2020] [Indexed: 12/19/2022] Open
Abstract
Purpose There has been an increasing clinical interest in specific retinal parameters as non-invasive biomarkers of retinal inflammation in diabetic macular edema (DME) that have been shown to have prognostic value, such as hyperreflective retinal fields (HRFs) and subfoveal neuroretinal detachment (SND). Methods We conducted a prospective, non-comparative study of treatment-naïve patients with DME to evaluate the efficacy of a Pro Re Nata (PRN) regimen of intravitreal dexamethasone implant 0.7 mg (DexI, Ozurdex™). After administration, patients underwent subsequent injections according to PRN criteria in case of edema relapse, but not earlier than 4 months after the previous treatment. Patients were evaluated at baseline, within 15 days of injection, and every month thereafter. During all visits, best-corrected visual acuity (BCVA) was recorded; central retinal thickness (CRT), type of edema, presence of SND, and presence and number of HRFs were evaluated using swept-source optical coherence tomography (SS-OCT) 3D. Treatment outcome was defined as changes in BCVA, CRT, SND and HRFs at 12 (T12) and 24 (T24) months compared with baseline (T0). Results The study enrolled 24 eyes of 18 patients. The mean duration of follow-up was 18±6.6 months; for all eyes, T12 data were available, while follow-up reached T24 for 12 eyes. BCVA improved significantly and CRT decreased significantly during treatment; the edema was no longer detectable in 13/24 eyes at T12 and 8/12 eyes at T24. No patient presented SND at T12 and T24, and the mean number of HRFs decreased significantly during treatment. Results with CRT and HRFs correlated with BCVA at 12 and 24 months. No significant adverse events were observed. Conclusion In patients with DME, the intravitreal dexamethasone implant was effective and safe in improving both functional and tomographic parameters. This result is consistent with improvement in biomarkers of inflammation.

Abstract
PURPOSE Intravitreal corticosteroid implants based on sustained-release dexamethasone provide effective retinal delivery of drug for around 6 months for the treatment of diabetic macular edema (DME). As current recommendations on the management of patients with DME undergoing cataract surgery are limited, this article aims to highlight issues and provide guidance on the use of dexamethasone intravitreal implants (DEX-DDS) in patients with DME undergoing cataract surgery, based on the consensus findings of a panel of Italian experts. METHODS The panel developed a survey regarding the use of DEX-DDS in patients with DME undergoing cataract surgery, following a comprehensive literature search. The results of the survey were discussed at an experts' meeting in September 2018, with a structured approach to determining consensus. The routine management of patients with DME undergoing cataract surgery was also developed for use as a basis of discussion to highlight current issues. RESULTS Eight consensus statements are presented, along with key issues that highlight controversial/outstanding issues in the use of DEX-DDS in DME patients with cataracts. CONCLUSION The consensus statements can help provide practical guidance for clinicians in daily practice on the rationale, patient diagnosis and selection, and optimal management of patients with DME undergoing cataract surgery.
