Abstract
Glucocorticoid (GC) therapy is indicated in many diseases, including ocular diseases. An important side-effect of GC therapy is GC-induced ocular hypertension (GIOHT), which may cause irreversible blindness known as GC-induced glaucoma (GIG). Here, we reviewed the pathological changes that contribute to GIOHT including in the trabecular meshwork and Schlemm's canal at cellular and molecular levels. We also discussed the clinical aspects of GIOHT/GIG including disease prevalence, risk factors, the type of GCs, the route of GC administration, and management strategies.

Abstract
BACKGROUND The ILUVIEN Registry Safety Study was a multicentre, open-label, non-randomised, observational, phase 4 study designed to assess the safety and effectiveness of the fluocinolone acetonide (FAc) implant in all indications in real-world practices in Europe. METHODS The study included data collected prospectively and retrospectively. Patients receiving FAc implants between 2013 and 2017 were included and monitored until the last patient reached ≥3 years of follow-up. Mean intraocular pressure (IOP) data over the course of the study, along with IOP events, use of IOP-lowering therapy, mean change in visual acuity (VA) and information on supplemental therapy use were analysed post-FAc implantation. RESULTS Six hundred and ninety-five eyes from 556 patients, with a mean±SD follow-up of 1150.5±357.36 days, were treated with a FAc implant. 96.7% of eyes had chronic diabetic macular oedema (cDMO). IOP lowering was achieved in 34.5% of eyes using topical agents and 4.3% by surgery. Seventy-three eyes (64.6% of 113 phakic) required cataract surgery during follow-up. Mean VA increased from a baseline of 52.2 letters to 57.1 letters at month 36, with improvement observed up to month 48. Supplementary therapies were given in 43.7% of eyes. When classified by length of cDMO less than or greater than the median duration those with a shorter history experienced greater VA gains than those with a longer history. CONCLUSION This study confirms the favourable, long-term benefit-to-risk profile of the FAc implant in eyes with cDMO, with an additional benefit in patients when this therapy is administered earlier.

Abstract
Branch retinal vein occlusions are a significant cause of vision loss and present several ophthalmic and systemic risk factors, including age, hypertension, hyperlipidemia and glaucoma. Retinal vein occlusion is the second-most-common retinal vascular disease. This study evaluated the effects of Ozurdex in contrast to a combination therapy with anti-vascular endothelial growth factor (VEGF) and cortisone in treatment-naive branch retinal vein occlusions-macular edema (BRVO-ME) cases, at 4-month and 6-month follow-ups. Thirty eyes were included in the study, which were divided into two groups. The first group consisted of 15 eyes, and each received 1 injection of dexamethasone intravitreal implant Ozurdex (DEX). The second group of 15 eyes received 3 intravitreal injections, the first and second with the anti-vascular endothelial growth factor aflibercept and the third one with 4 mg of triamcinolone acetonide (Vitreal S), spaced at one month. The best corrected visual acuity (BCVA) results suggested that the peak efficacy was at 4 months for both groups, with mean values of 0.5 LogMAR and 0.4 LogMAR. Regarding macular edema, there were no significant changes between the 4- and 6-month follow-up periods, with mean values of 361 μm and 390 μm. Six patients experienced transient raised intraocular pressure at one week after treatment. This study highlights the benefits to visual acuity of the combination of anti-vascular endothelial growth factor and cortisone, which represents a viable solution with similar results to Ozurdex therapy.

Abstract
Introduction The 0.19 mg fluocinolone acetonide (FAc) intravitreal implant delivers a continuous intravitreal corticosteroid dose for the treatment of refractory diabetic macular oedema (DMO). The aim of this study was to assess the impact of an FAc intravitreal implant on intraocular pressure (IOP). Methods We retrospectively collected anonymised data on the patients’ characteristics, DMO treatment, and IOP and IOP-lowering treatments before and after the FAc intravitreal implant between September 2013 and March 2020 in several European centres. Results A total of 221 eyes from 179 patients were included. The mean follow-up duration was 13.4 (± 12.5, range 2.4–33.5) months. Overall, 194 eyes (88.2%) had received an intravitreal dexamethasone injection before the FAc intravitreal implant. For 25 eyes (11.3%) there was a history of glaucoma, and 52 eyes (23.5%) had previous IOP-lowering treatment. Mean IOP before injection was 14.7 (3.4) mmHg and increased to 16.9 (3.7) mmHg 12 months after injection (P < 0.0001). During follow-up, 55 eyes (24.9%) required the addition or initiation of topical IOP-lowering medication, only one patient (0.5%) had laser trabeculoplasty and one patient (0.5%) a minimally invasive glaucoma surgery, and no patient required incisional IOP-lowering surgery. Conclusion The FAc intravitreal implant led to substantial IOP elevation. This elevation was monitored most of the time with addition or initiation of topical IOP-lowering medication.

Abstract
Center-involving diabetic macular edema (DME) is a leading cause of vision impairment in working-age adults. While its management is particularly challenging in a poorly compliant population, continuous innovation and the advent of new molecules have improved its outcome. The control of glycemia and of systemic aggravating factors remain essential to slow down progression of disease complications including DME. The indications for macular laser photocoagulation has progressively been phased out as a standard of care and replaced by local intraocular anti-VEGFs biologics and glucocorticoids (GCs). Intravitreal GCs in controlled-release drug delivery systems have allowed to reduce injection frequency and treatment burden. The non biodegradable Fluocinolone Acetonide (FAc) implant allows a long-lasting stabilization of both functional and anatomic improvements. However, adequate patient selection and monitoring through regular follow-up are essential for optimal results. Based on their experience and the latest literature, the aim of the present review is to provide international expert panel consensus on the place of the FAc implant in the treatment algorithm of DME, as well as its safety profile and how to manage it.

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
Blood-retinal barrier (BRB) dysfunction underlies macular oedema in many sight-threatening conditions, including diabetic macular oedema, neovascular age-related macular degeneration and uveoretinitis. Inflammation plays an important role in BRB dysfunction. This study aimed to understand the role of the inflammatory cytokine IL-17A in BRB dysfunction and the mechanism involved. Human retinal pigment epithelial (RPE) cell line ARPE19 and murine brain endothelial line bEnd.3 were cultured on transwell membranes to model the outer BRB and inner BRB, respectively. IL-17A treatment (3 days in bEnd.3 cells and 6 days in ARPE19 cells) disrupted the distribution of claudin-5 in bEnd.3 cells and ZO-1 in ARPE19 cells, reduced the transepithelial/transendothelial electrical resistance (TEER) and increased permeability to FITC-tracers in vitro. Intravitreal (20 ng/1 μL/eye) or intravenous (20 ng/g) injection of recombinant IL-17A induced retinal albumin leakage within 48 h in C57BL/6J mice. Mechanistically, IL-17A induced Janus kinase 1 (JAK1) phosphorylation in bEnd.3 but not ARPE19 cells. Blocking JAK1 with Tofacitinib prevented IL-17A-mediated claudin-5 dysmorphia in bEnd.3 cells and reduced albumin leakage in IL-17A-treated mice. Our results suggest that IL-17A can damage the BRB through the activating the JAK1 signaling pathway, and targeting this pathway may be a novel approach to treat inflammation-induced macular oedema.

Abstract
Corticosteroids remain the mainstay of the treatment for various ocular conditions affecting the ocular surface, anterior and posterior segments of the eye due to their anti-inflammatory, anti-oedematous, and anti-neovascularization properties. Prednisolone, prednisolone acetate, dexamethasone, triamcinolone acetonide, fluocinolone acetonide, and loteprednol etabonate are amongst the most widely used ophthalmic corticosteroids. Corticosteroids differ in their activity and potency in the eye due to their inherent pharmacological and pharmaceutical differences. Different routes and regimens are available for ocular administration of corticosteroids. Conventional topical application to the eye is the route of choice when targeting diseases affecting the ocular surface and anterior segment, while periocular, intravitreal, and suprachoroidal injections can be potentially effective for posterior segment diseases. Corticosteroid-induced intraocular pressure elevation and cataract formation remain the most significant local risks following topical as well as systemic corticosteroid administration. Invasive drug administration via intracameral, subconjunctival, and intravitreal injection can enhance ocular bioavailability and minimize dose and dosing frequency of administration, yet may exacerbate ocular side effects of corticosteroids. This review provides a critical appraisal of the ophthalmic uses of corticosteroid, routes of administration, drug delivery fundamentals and novel ocular implantable steroid delivery systems, factors influencing side effects, and future perspectives for ocular corticosteroid therapy.

Abstract
Purpose: To investigate the associations between early anatomical responses and intraocular pressure (IOP) changes in macular edema (ME) due to retinal vascular diseases treated with an intravitreal dexamethasone (DEX) implant. Methods: A retrospective review was conducted involving ME patients who underwent intravitreal DEX implantation. The eyes were divided into increased IOP (IIOP) or non-IIOP (nIIOP) groups according to the presence or absence of significant IOP elevation. Significant IOP elevation was defined by both the absolute value of IOP elevation (5 mmHg or higher) and an elevation percentage of the baseline IOP (an increase equal to 30% of the pre-injection IOP or higher). We analyzed the difference in central subfield thickness (CST) change according to the IOP elevation after DEX implantation. Relationships between IOP change and CST reduction after intravitreal DEX implantation were analyzed by Pearson correlation coefficients. Results: A total of 49 eyes, 29 with diabetic ME and 20 with ME due to retinal vein occlusion (RVO), were included in this study. Of the 49 eyes, 18 eyes (36.7%) were classified as IIOP group and 31 (63.3%) as nIIOP group. Significant differences in mean CST reductions over baseline one week after DEX implantation were observed between the groups. The degree of CST reduction from baseline to 1 week was significantly correlated with the degree of IOP change from baseline at 1 week and 1 month after intravitreal DEX implantation. Conclusions: In patients with ME due to retinal vascular diseases, we noted an early anatomical response significantly correlated with IOP change after intravitreal DEX implantation. Therefore, patients with favorable early anatomical responses to DEX implantation should be carefully monitored for IOP elevation.

Abstract
Current management of diabetic macular edema (DME) predominantly involves treatment with short-acting intravitreal injections of anti-vascular endothelial growth factors (anti-VEGFs) and/or corticosteroids; however, short-acting therapies (lasting between 1 and 6 months) require frequent injections to maintain efficacy, meaning a considerable treatment burden for diabetic patients with multiple comorbidities. Continuous injections needed in some cases are an economic burden for patients/healthcare system, so real-life clinical practice tends to adopt a reactive approach, ie, watch and wait for worsening symptoms, which consequently increases the risk of undertreatment and edema recurrence. On March 7th 2019, a group of experts in retinal medicine and surgery held a roundtable meeting in Madrid, Spain to discuss how to (1) optimize clinical outcomes through earlier use of fluocinolone acetonide (FAc) implant (ILUVIEN®) in patients with persistent or recurrent DME despite therapy; and, (2) to provide guidance to assist physicians in deciding which patients should be treated with ILUVIEN. In this regard, a 36-month follow-up consensus protocol is presented. In conclusion, patients that achieve a complete or partial anatomical, and preferably functional, response following one or two intravitreal dexamethasone implants, but with recurrence of edema after 3-4 months, are deemed by the authors most likely to benefit from ILUVIEN, and the switch to FAc implant should not be delayed more than 12 months after the initiation of at least the first dexamethasone implant.

Aims: To evaluate treatment outcomes of pro re nata dosing of intravitreal dexamethasone implant in eyes with refractory diabetic macular edema (DME) amongst Indian subjects. Methods and material: Retrospective, interventional case series. Medical records of 28 eyes of 23 patients with refractory DME who underwent intravitreal dexamethasone (700 µ) implant were reviewed. Paired t-test was carried out to measure mean change in the parameters evaluated. Mann-Whitney U test and Fisher’s exact t-test were done to explore differences between groups receiving single or multiple injections. Results: Best corrected visual acuity (BCVA) and central macular thickness (CMT) at baseline were 0.85 (±0.44) and 612 µm (±123), respectively. Mean CMT over 6 months (measured monthly) following injection was 340±119 µm (p=0.001), 346±150 µm (p=0.02), 368±169 µm (p=0.02), 304±174 µm (p=0.001), 525±216 µm (p=0.94) and 532±201 µm (p=0.46), respectively. Mean BCVA at each month following injection was 0.68±0.36 (p=0.02), 0.75±0.45 (p=0.42), 0.55±0.40 (p=0.11), 0.63±0.40 (p=0.12), 0.78±0.30 (p=0.90) and 0.60±0.47 (p=0.92), respectively. Mean follow-up was 12 months (range: 6–33 months). Mean BCVA and CMT at mean 12 months were 0.72±0.46 (p=0.10) and 358 µm±189 (p=0.0001), respectively. Seven eyes had raised IOP; five eyes required cataract extraction. Conclusions: Intravitreal dexamethasone implant is effective in treatment of refractory DME. However, its therapeutic effect lasts for about 4 months.

Abstract
Glucocorticoids are a class of anti-inflammatory drugs commonly used to treat various ocular and systemic conditions. Although the role of glucocorticoids in the treatment of numerous serious inflammatory diseases is pivotal, their prolonged use may increase intraocular pressure resulting in steroid-induced glaucoma. We provide a detailed update on steroid-induced glaucoma as a preventable cause of blindness in the adult and pediatric population and describe its epidemiology, social impact, and risk factors. Furthermore, we explore the propensity of different steroids to increase the intraocular pressure, the role of different routes of steroid administration, dosage and duration of treatment, as well as the clinical features, genetics, and management of steroid-induced glaucoma.

Abstract
INTRODUCTION Intravitreal injections (IVI) of slow-release dexamethasone (DEX) are generally well tolerated. Ocular hypertension (OHT) and cataracts are the most common adverse effects of DEX-implant (DEX-I). MATERIAL AND METHODS The cases reported concern 5 eyes in four DEX-I IVI high-responder patients whose intraocular pressure (IOP) returned to normal after administration of a XEN gel stent with mitomycin subconjunctival injection, thus allowing the continued use of DEX-I which was the only therapeutic option for these patients. All patients were pure steroid responders with normal optic nerves. RESULTS No hypertension was observed in any of the eyes after DEX-implant intravitreal reinjection following XEN-surgery.All patients were successfully treated with XEN surgery and were retreated with DEX-implant with no further increase in IOP. The mean duration of follow-up after the MIGS procedure was 5 months (min-max, 2-12). None of the patients required needling. CONCLUSIONS XEN gel stent would seem to represent a safe and effective solution for treating steroid-induced hypertension. It allows for the medium and long-term use of DEX-I in high responders. It could be of clinical interest to study this combination in a prospective trial with a large number of patients and long-term follow-up.

Abstract
BACKGROUND Currently two intravitreally applied corticosteroids (dexamethasone and fluocinolone) are licensed in Germany for treatment of diabetic macular oedema (DME). The use of DEX implant for DME in daily clinical practice has not been defined in detail. Following a Delphi panel survey, a group of retina experts set out to come up with a consensus for use of the DEX implant in DME. MATERIAL AND METHODS International and national treatment recommendations were identified from the literature. A steering group generated a catalogue of 72 statements on the aetiology and pathogenesis of DME, therapy with DEX implant, use of DEX implant in patients previously treated with VEGF-inhibitors, use of DEX implant in combination therapy, safety of DME therapies as well as patients' burden of treatment. Twenty-two ophthalmologists from private practice and 6 hospital ophthalmologists participated in the Delphi panel via Survey Monkey. Consensus was reached if at least 75% of participants agreed or disagreed with a statement. Statements for which consensus was not reached were discussed once more during the expert consensus meeting and a vote was taken. Based on these results a treatment algorithm for foveal DME was proposed. RESULTS If a patient does not show sufficient response after 3 - 6 months of anti-VEGF treatment (visual acuity gain of < 5 ETDRS letters or reduction of central retinal thickness ≤ 20%), a switch to DEX implant should take place. DEX implant is also suitable in eyes with longer presentation of DME, showing e.g. massive lipid exudates. DEX implant is suitable as first-line therapy especially in pseudophakic patients, patients unwilling or able to comply with tight anti-VEGF injection intervals or patients with known vascular diseases. With fixed control visits every 4 - 8 weeks, use of DEX implant is flexible and individual. Decision parameters for repeated use should be visual acuity, retinal thickness and intraocular pressure. Treatment of both eyes on the same day should not take place. CONCLUSION The algorithm presented reflects survey as well as expert discussion results and may differ from recommendations issued by the German professional society. The consensus recommendations for the treatment of DME generated during the survey and meeting of retina experts are intended to guide use of DEX implant in daily practice.

Abstract
We present the case of a patient who had several intravitreal methotrexate injections due to a uveitic macular edema and a known steroid response. An earlier off-label therapy with avastin had not been successful. After the intravitreal methotrexate injections a good resorption of the retinal fluid as well as a good intraocular pressure and a good visual acuity could be achieved. Visual acuity was limited by pre-existing glaucomatous optic nerve atrophy and a central scar in the cornea.

Abstract
PURPOSE To determine the utility of the dexamethasone implant (IVD) as an alternative to systemic steroids as prophylaxis against cystoid macular edema (CMO) in patients with chronic, recurrent CMO associated intermediate or posterior uveitis (IU/PU), and cataract undergoing cataract surgery. METHODS This was a randomized, parallel design, and clinical trial. Patients with IU/PU and cataract scheduled for cataract surgery were randomly assigned to receive the IVD concurrently with cataract surgery (Group 1: 20 patients) or systemic steroids (Group 2: 23 patients) tapered over 4-6 weeks along with uneventful cataract surgery and routine postoperative care. Patients with glaucoma/contraindications to steroids were excluded. All patients were followed up for 6 months. OUTCOME MEASURE Primary-incidence of postoperative CMO. Secondary-the change in BCVA (corrected distance visual acuity) and Central Subfield thickness (CST) and complications. Appropriate statistical analysis was done. RESULTS The median age was 47.3 ± 4.23 years (group 1) and 49.12 ± 5.32 years (Group 2). One patient (Group 1) and two (Group 2) developed CMO. The BCVA improved significantly in both groups (p = 0.013). The CST change was insignificant. Four patients (Group 1) required intraocular pressure (IOP) lowering medications. Three patients (Group 2) required early steroid taper. CONCLUSIONS IVD is a good alternative as prophylaxis in IU/PU and cataract in preventing postoperative CMO.

Abstract
The aim of this article is to provide an overview of characteristics and principles of use of dexamethasone implant in patients with diabetic macular edema (DME). The condensed information about patient selection, dosing, and postinjection management is provided to make the clinician’s decisions easier in real-life practice. DME is a common complication of diabetes and the leading cause of visual loss in the working-age population. Inflammation plays an important role in the pathogenesis of DME. The breakdown of the blood–retinal barrier involves the expression of inflammatory cytokines and growth factors, including vascular endothelial growth factor (VEGF). Steroids have proved to be effective in the treatment of DME by blocking the production of VEGF and other inflammatory cytokines, by inhibiting leukostasis, and by enhancing the barrier function of vascular endothelial cell tight junctions. Dexamethasone intravitreal implant has demonstrated efficacy in the treatment of DME resistant to anti-VEGF therapy and in vitrectomized eyes. Data from clinical trials suggest that dexamethasone implant can be considered as first-line treatment in pseudophakic eyes. Dexamethasone implant is also the first-line therapy in patients not suited for anti-VEGF therapy, pregnant women, and patients unable to return for frequent monitoring. It has been shown that the maximum effect of dexamethasone implant on visual gain and retinal thickness occurs approximately 2 months after injection. Various treatment regimens are used in real-life situations, and reported reinjection intervals were usually <6 months. The number of retreatments needed decreased over time. Treatment algorithms should be personalized. Postinjection management and follow-up should consider potential adverse events such as intraocular pressure elevation and cataract.

Abstract
The objective of this study was to develop a clear aqueous mixed nanomicellar formulation (NMF) of triamcinolone acetonide (TA) with a combination of nonionic surfactant hydrogenated castor oil 60 (HCO-60) and octoxynol-40 (Oc-40). In order to delineate the effects of drug-polymer interactions on entrapment efficiency (EE), loading efficiency (LE), and critical micellar concentration (CMC), a design of experiment (DOE) was performed to optimize the formulation. In this study, full-factorial design has been used with HCO-60 and OC-40 as independent variables. All formulations were prepared following solvent evaporation and film rehydration method, characterized with size, polydispersity, shape, morphology, EE, LE, and CMC. A specific blend of HCO-60 and Oc-40 at a particular wt% ratio (5:1.5) produced highest drug EE, LE, and smallest CMC (0.0216 wt%). Solubility of TA in NMF improved 20 times relative to normal aqueous solubility. Qualitative 1H NMR studies confirmed the absence of free drug in the outer aqueous NMF medium. Moreover, TA-loaded NMF appeared to be highly stable and well tolerated on human corneal epithelial cells (HCEC) and human retinal pigment epithelial cells (D407 cells). Overall, these studies suggest that TA in NMF is safe and suitable for human topical ocular drop application.

Abstract
The first-line therapy for patients with center-involving diabetic macular edema (DME) is with intravitreal anti-vascular endothelial growth factor (VEGF) agents, with or without adjunctive macular laser treatment. However, a significant proportion of patients have persistent and recurrent edema despite repeated anti-VEGF injections. The fluocinolone acetonide (FA) 190 μg intravitreal implant has been shown in pivotal clinical trials to be efficacious for the treatment of DME and has been approved in many countries for use in patients who have not responded to first-line therapy. In this report, we have collated the latest data from the increasing number of studies to illustrate the pattern of usage of the Iluvien FA implant for DME during the current anti-VEGF era. We have shown that there is now a wealth of published evidence from real-world studies to support the clinical utility of the FA implant in achieving further resolution of edema and improving visual acuity outcomes in this challenging group of patients.

Abstract
Purpose To report the 12-months visual and anatomical outcomes of chronic diabetic macular oedema (DMO) treated with ILUVIEN in a real-world clinical practice in a single tertiary referral centre. Method Retrospective data collection and analysis of consecutive 28 eyes of 23 diabetic patients received ILUVIEN implant for refractory DMO. Standard assessment included visual acuity (VA), central retinal thickness (CRT), slit-lamp biomicroscopy, and Goldmann tonometry for intraocular pressure (IOP) at 1, 6, and 12 months. Results Baseline mean VA was 47 (SD 18) letters improved to 55 (SD 17) letters (P=0.004) at 12 months. VA was improved in 16 eyes (57%), stabilised in 9 eyes (32%), and decreased in 3 eyes (11%). Seven eyes (25%) gained ≥15 letters, and 10 eyes (36%) gained >10 letters from baseline. The percentage of eyes achieved driving vision (≥70 Early Treatment Diabetic Retinopathy Study letters) was doubled from baseline 18 to 36% at 6 months and 32% at 12 months. Mean CRT decreased by 198 μm from baseline 494 μm (SD 191) to 296 μm (SD 121) at 12 months (P<0.001). Two eyes received additional anti-vascular endothelial growth factor injections after 10 months. Complications: Raised IOP in three eyes (11%) controlled with IOP-lowering drops, vitreous haemorrhage in one eye and one endophthalmitis (1 year vision improved to 6/24). Conclusion Our real-world results show that the visual and the anatomical improvements achieved by a single ILUVIEN implant injection were maintained up to 12 months with minimal adjunctive therapy. IOP monitoring remains essential in ILUVIEN patients, although our study shows a relatively low risk of IOP elevation post ILUVIEN injection, even in existing controlled ocular hypertension. Our results demonstrate that ILUVIEN is an effective long-term option in treating chronic refractory DMO.

Abstract
PURPOSE The aim of this study was to explore and describe quantitatively patient-reported outcome measures (PROMs), ie, health-related quality of life (QoL), visual function and treatment satisfaction, in patients with diabetic macular edema (DME) receiving two different regimens of Ozurdex (intravitreal dexamethasone implant). METHODS In this multicenter, prospective study, 100 patients with center-involving refractory DME were randomized 1:1 to either five monthly fixed dosing or optical coherence tomography (OCT)-guided pro re nata (PRN) regimen of dexamethasone intravitreal implant therapy. The primary outcome was the difference between arms in change in PROMs and health-related QoL from baseline to 12 months, as measured by the Retinopathy-Dependent Quality of Life (RetDQoL) questionnaire, Visual Function Questionnaire-25 (VFQ-25) and Retinopathy Treatment Satisfaction Questionnaire (RetTSQ). RESULTS There was no statistically significant difference in the RetDQoL score and VFQ-25 score at month 12 compared to those at baseline, whereas the total mean RetTSQ score increased significantly at the exit visit. The two treatment arms did not differ significantly regarding the change in PROMs and health-related QoL questionnaires. Logistic regression analysis showed that visual acuity (VA) of ≥55 letters, central foveal thickness <300 μm and macular volume <9.2 mm3 at the exit visit (month 12) predicted a higher change in RetTSQ. CONCLUSION This study showed that there is a statistically significant improvement in treatment satisfaction, as measured by RetTSQ, in patients with DME treated with dexamethasone intravitreal implant, independent of the dose regimen, namely, fixed or PRN. However, it should be noted that the clinically meaningful change could not be assessed accurately, since no thresholds for clinically meaningful change currently exist for the RetTSQ. On the other hand, there was no significant change in health-related QoL, as measured using VFQ-25 and RetDQoL. Factors affecting the patients' treatment satisfaction were the final VA, the central foveal thickness and the macular volume.
