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
Diabetic macular edema (DME) is a common sight-threatening complication of diabetic retinopathy (DR) and the leading cause of severe visual impairment among the working-age population. Several therapeutic options are available for the management of DME, including intravitreal corticosteroids. They have been traditionally used as second-line treatment, due to the risk of intraocular pressure increase and cataract-related adverse events. However, attention has recently been focused on the primary or early use of intravitreal corticosteroids, due to growing evidence of the crucial role of inflammation in the pathogenesis of DME. Furthermore, intravitreal steroid implants offer the additional advantage of a longer duration of action compared to anti-vascular endothelial growth factor agents (anti-VEGF). This review aims to summarize the available evidence on the efficacy and safety profile of dexamethasone (DEX) intravitreal implant, with a specific focus on clinical scenarios in which it might be considered or even preferred as first-line treatment option by adequate selection of patients, considering both advantages and possible adverse events. Patients with contraindications to anti-VEGF, DME with high inflammatory OCT biomarkers, pseudophakic patients and phakic patients' candidates to cataract surgery as well as vitrectomized eyes may all benefit from first-line DEX implant. Additionally, DME not responders to anti-VEGF should be considered for a switch to DEX implant and a combination therapy of DEX implant and anti-VEGF could be a valid option in severe and persistent DME.

Abstract
To investigate local ocular factors associated with the development of diabetic macular edema (DME), we classified each eye of patients with unilateral DME as the DME eyes or the fellow eyes (without DME). We compared the clinical characteristics, optical coherence tomography (OCT), and OCT angiography (OCTA), ultra-wide field fundus photography, and angiography features of each eye. As a result, fifty-five patients with unilateral DME were enrolled. Although the diabetic retinopathy stage was not different between each group of eyes, DME eyes showed a higher prevalence of venous beading and a larger area of nonperfusion region than did fellow eyes (all P < 0.05). OCTA features of DME eyes also showed a larger foveal avascular zone in the deep capillary plexus and a lower vascular density in both the superficial and deep capillary plexuses (all P < 0.05). This study highlighted ocular features reflecting retinal ischemia, such as venous beading, area of nonperfusion region, and vascular density in the central retinal area, are associated with the development of DME. OCTA and ultra-wide field fluorescein angiography may be useful for evaluating the parameters of retinal ischemia and the risk of DME development.

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.

Abstract
PURPOSE To assess the safety and efficacy of intraoperative dexamethasone intravitreal (DEX) implant in patients with diabetic macular edema (DME) undergoing femtosecond laser assisted cataract surgery (FLACS). METHODS In this single-center retrospective study, the charts of patients who underwent combined FLACS and DEX implant in the previous three months were reviewed. Primary outcome measures were ocular complications; secondary outcome measures were the change of best-corrected visual acuity (BCVA) and central retinal thickness (CRT). RESULTS 20 eyes of 20 patients were included. None developed intraoperative or postoperative complications. Mean BCVA was 20/120 (logMAR, 0.78 ± 0.31) at baseline and improved significantly to 20/63 (logMAR, 0.52 ± 0.24; p = 0.01), 20/58 (LogMAR, 0.48 ± 0.28; p < 0.001) and to 20/58 (LogMAR, 0.48 ± 0.31; p < 0.001) at month 1,2 and 3, respectively. A mean improvement of 0.30 LogMAR was recorded at month 1 and 3. Mean CRT decreased significantly from 416.6 ± 76.1 μm at baseline to 322.4 ± 46.4 μm (p < 0.001), to 300.7 ± 29.7 μm (p < 0.001), and to 319.8 ± 54.7 μm (p < 0.001) at month 1,2 and 3, respectively. Comparing to the 1-month follow-up, the largest mean reduction in CRT (112.4 ± 68.9 µm) was observed at month 2 (p = 0.001). Fourteen patients (70%) had an improvement of CRT over the first 2 months followed by a recurrence of edema at month 3. CONCLUSION DEX implant following FLACS seems to be a safe and effective approach for patients with coexisting cataract and DME.

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.

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
Macular edema (ME) is associated with various conditions; however, the main causes of ME are retinal vein occlusion (RVO) and diabetes. Laser photocoagulation, formerly the gold standard for the treatment of ME, has been replaced by anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections. Despite its efficiency, this treatment requires frequent injections to preserve the outcomes of anti-VEGF therapy, and as many patients do not sufficiently respond to the treatment, ME is typically a chronic condition that can lead to permanent visual impairment. Generalized recommendations for the treatment of ME are lacking, which highlights the importance of reviewing treatment approaches, including recent anti-VEGFs, intravitreal steroid implants, and subthreshold micropulse lasers. We reviewed relevant studies, emphasizing the articles published between 2019 and 2021 and using the following keywords: macular edema, diabetic macular edema, retinal vein occlusion, laser photocoagulation, anti-VEGF, and intravitreal injections. Our results revealed that a combination of different treatment methods may be beneficial in resistant cases. Additionally, artificial intelligence (AI) is likely to help select the best treatment option for patients in the near future.

Abstract
Diabetic macular edema (DME) is a common cause of moderate visual impairment among people with diabetes. Due to the rising number of people with diabetes in India, the absolute numbers of people with DME are significant. There are several treatment options for DME, and the choice of treatment is based on the availability of retinal specialists and infrastructure for the delivery of treatment. A major challenge is the out-of-pocket expenditure incurred by patients as most treatment options are costly. Treatment also varies based on the associated ocular and systemic conditions. The All India Ophthalmology Society (AIOS) and the Vitreo-Retinal Society of India (VRSI) have developed this consensus statement of the AIOS DR task force and VRSI on practice points of DME management in India. The objective is to describe the preferred practice patterns for the management of DME considering the different presentations of DME in different clinical scenarios.

Early DMO: a predictor of poor outcomes following cataract surgery in diabetic patients. The DICAT-II study. Eye (Lond) 2021; 36:1687-1693. [PMID: 34345028 PMCID: PMC8330474 DOI: 10.1038/s41433-021-01718-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 06/28/2021] [Accepted: 07/22/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The prospective DIabetes and CATaract Study II (DICAT II) was performed to characterise the risks of cataract surgery to the retinae of patients with early diabetic macular oedema (E-DMO). METHODS DICAT II was a prospective, comparative, multicentre, observational study involving six Italian clinics. Patients were aged ≥55 years, had type 1 or 2 diabetes with spectral-domain optical coherence tomography evidence of ESASO classification Early DMO. Group 1 eyes (78 eyes, 78 patients) underwent phacoemulsification-based cataract surgery. Group 2 eyes (65 eyes, 65 patients) had E-DMO and either clear media or had undergone uncomplicated cataract surgery ≥1 year previously. Central subfield thickness (CST) and best-corrected visual acuity (BCVA) were assessed in both groups. RESULTS The negative impact of surgery on CST was evident after the first postoperative week; CST peaked during the first month, then rapidly decreased. CST worsening ≥10 µm was observed in 63/78 eyes (80.7%) and 29/65 eyes (44.6%) in Groups 1 and 2, respectively (p < 0.0001). CST worsening of ≥50 µm was observed in 51 eyes (65.4%) and 10 eyes (15.4%) in Groups 1 and 2, respectively (p < 0.0001). Mean CST worsening was lower in Group 2 than in Group 1 (38.6 ± 30.4 µm vs 85.5 ± 55.3 µm, p < 0.0001) with a lower BCVA loss (-2.6 ± 3.5 letters vs -8.2 ± 6.2 letters, p < 0.0001). Higher glycaemic levels and HBA1c levels were significantly associated with the risk of >50 μm CST worsening in eyes from both groups. CONCLUSION Early DMO is associated with poorer outcomes after cataract surgery and requires close pre- and postoperative monitoring.

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.
