A high-dose formulation of intravitreal aflibercept (8 mg) could improve treatment outcomes in diabetic macular oedema (DMO) by requiring fewer injections than the standard comparator, aflibercept 2 mg. We report efficacy and safety results of aflibercept 8 mg versus 2 mg in patients with DMO. PHOTON was a randomised, double-masked, non-inferiority, phase 2/3 trial performed at 138 hospitals and specialty retina clinics in seven countries. Eligible patients were adults aged 18 years or older with type 1 or 2 diabetes and centre-involved DMO. Patients were randomly assigned (1:2:1) to intravitreal aflibercept 2 mg every 8 weeks (2q8), aflibercept 8 mg every 12 weeks (8q12), or aflibercept 8 mg every 16 weeks (8q16), following initial monthly dosing. From week 16, dosing intervals for the aflibercept 8 mg groups were shortened if patients met prespecified dose regimen modification criteria denoting disease activity. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48 (non-inferiority margin of 4 letters). Efficacy and safety analyses included all randomly assigned patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov (NCT04429503). Between June 29, 2020, and June 28, 2021, 970 patients were screened for eligibility. After exclusions, 660 patients were enrolled and randomly assigned to receive aflibercept 8q12 (n=329), 8q16 (n=164), or 2q8 (n=167); two patients were randomly assigned in error and did not receive treatment. 658 (99·7%) patients were treated and included in the full analysis set and safety analysis set (8q12 n=328, 8q16 n=163, and 2q8 n=167). Mean patient age was 62·3 years (SD 10·4). 401 (61%) patients were male. 471 (72%) patients were White. Aflibercept 8q12 and 8q16 demonstrated non-inferior BCVA gains to aflibercept 2q8 (BCVA mean change from baseline 8·8 letters [SD 9·0] in the 8q12 group, 7·9 letters [8·4] in the 8q16 group, and 9·2 letters [9·0] in the 2q8 group). The difference in least squares means was –0·57 letters (95% CI –2·26 to 1·13, p value for non-inferiority <0·0001) between 8q12 and 2q8 and –1·44 letters (–3·27 to 0·39, p value for non-inferiority 0·0031) between aflibercept 8q16 and 2q8. Proportions of patients with ocular adverse events in the study eye were similar across groups (8q12 n=104 [32%], 8q16 n=48 [29%], and 2q8 n=46 [28%]). Aflibercept 8 mg demonstrated efficacy and safety with extended dosing intervals and could decrease treatment burden in patients with DMO. Regeneron Pharmaceuticals and Bayer.

In this 24-month, randomized trial involving patients with relapsing–remitting multiple sclerosis, oral fingolimod reduced the rates of relapse and disability progression, as compared with placebo. Adverse events reported in patients treated with fingolimod included bradycardia, atrioventricular conduction block, macular edema, elevations in liver-enzyme levels, and mild hypertension. In patients with relapsing–remitting multiple sclerosis, oral fingolimod reduced the rates of relapse and disability progression, as compared with placebo. Adverse events included bradycardia, atrioventricular conduction block, macular edema, elevations in liver-enzyme levels, and mild hypertension. Fingolimod (FTY720) is an oral sphingosine-1-phosphate–receptor modulator 1 that is currently being evaluated for the treatment of multiple sclerosis. There is evidence that fingolimod acts by preventing lymphocyte egress from lymph nodes. 2 , 3 This leads to a reduced infiltration of potentially autoaggressive lymphocytes into the central nervous system. 4 , 5 Preclinical findings also suggest that fingolimod may promote neuroprotective and reparative processes within the central nervous system through modulation of sphingosine-1-phosphate receptors expressed on neural cells. 6 – 12 A 6-month, phase 2, placebo-controlled study 13 and its open-label extension study 14 showed sustained suppression, for up to 5 years, of both relapse and inflammatory activity . . .

The safety profile of fingolimod is well established in clinical trials and post-marketing studies. This study aimed to evaluate the safety and tolerability of fingolimod in a cohort of Italian patients with relapsing-remitting multiple sclerosis (RRMS). This is a non-comparative, open-label, multicentre, interventional study conducted in patients with RRMS with no suitable alternative treatment option. Safety and tolerability of fingolimod 0.5 mg were assessed by recording adverse events (AEs) and serious AEs (SAEs). Of the 906 patients enrolled in the study, 91 % of the patients completed the study. AEs and SAEs were reported in 35.4 and 2.9 % of the patients, respectively. Most common AEs reported were headache (4.1 %), influenza (2.1 %), lymphopenia (1.8 %), asthenia (1.8 %) and pyrexia (1.8 %). Increased alanine aminotransferase levels and hypertension were reported as AE in 1.0 and 1.4 % of the patients, respectively. Macular oedema was reported in three patients. These results emphasize the safety of fingolimod in patients representing the real-world clinical practice in the Italian population. Fingolimod was safe and well tolerated in this population, which, compared to those enrolled in pivotal trials in terms of concomitant diseases and used medications, is broader.

Taxanes are a class of microtubule stabilising agents used to treat a wide range of malignancies. Taxane drug-induced cystoid macula oedema (TDICMO) is a known but rare complication of therapy. First reported with Docetaxel in 2003 and Paclitaxel in 2007, there are currently less than 20 cases of TDICMO in the literature. Although most cases resolve following taxane cessation, several authors have tried using carbonic anhydrase inhibitors or intravitreal bevacizumab to accelerate resolution or when taxane therapy cannot be discontinued. We report the first published case of TDICMO treated with a single-eye trial of topical dorzolamide versus intravitreal bevacizumab.

AimTo evaluate the effectiveness of dexamethasone intravitreal implant 0.7 mg (DEX; Ozurdex) monotherapy in the patient subgroup of the AUSSIEDEX study with treatment-naïve diabetic macular oedema (DME).MethodsThe open-label, prospective, phase 4, real-world study included pseudophakic eyes and phakic eyes scheduled for cataract surgery that were treatment-naïve or non-responsive to antivascular endothelial growth factors. No eyes were excluded based on baseline best-corrected visual acuity (BCVA) or central subfield retinal thickness (CRT). After the initial DEX injection at the baseline visit, reinjection was permitted at ≥16-week intervals. Week-16 and week-52 visits were mandatory. Primary endpoints were changes in mean BCVA and CRT from baseline to 52 weeks.ResultsOf 200 eyes enrolled in the AUSSIEDEX study, 57 were treatment-naïve. Baseline mean BCVA was 58.8 letters and baseline mean CRT was 418.6 µm; changes in mean BCVA and CRT from baseline to 52 weeks in this subgroup were 3.4 letters (p=0.042) and –89.6 µm (p<0.001), respectively, with a mean 2.5 injections. The change in mean CRT from baseline was –55.8 µm at week 16 (p<0.001). The most common adverse event was increased intraocular pressure (IOP), with 20.0% of eyes requiring IOP-lowering medication. One patient was discontinued due to increased IOP. No eyes required filtration surgery. No serious, treatment-related ocular adverse events were reported.ConclusionIn this largest prospective, real-world study of DEX monotherapy for DME to date, DEX significantly improved CRT and BCVA at 52 weeks in treatment-naïve eyes, without new safety concerns, supporting DEX use in treatment-naïve DME.Trial registration number NCT02731911.

BackgroundOf the side effects of prostaglandin analogues (PGAs), uveitis and cystoid macular oedema (CME) have significant potential for vision loss based on postmarket reports. Caution has been advised due to concerns of macular oedema and uveitis. In this report, we researched and summarised the original data suggesting these effects and determined their incidence.MethodsPreferred Reporting Items for Systematic review and Meta-Analyses guidelines were followed. Studies evaluating topical PGAs in patients with ocular hypertension or open angle glaucoma were included. MEDLINE, PubMed, EMBASE, CINAHL, Web of Science, Cochrane Library, LILACS and ClinicalTrials.gov were searched between 1946 and 2019. Experimental studies, animal studies and randomised studies with other intraocular pressure-lowering eye drops were excluded.Results214 studies (28 232 patients) met the inclusion criteria. Using prospective data, the incidence of uveitis and CME among PGA users were 62/28 232 (0.22%) and 25/28 232 (0.09%), respectively. A higher frequency of both uveitis and CME were found among latanoprost users compared with bimatoprost. There were 21 case studies reporting CME including 48 eyes in 43 patients. 47 of 48 eyes (97.9%) had previous incisional ocular surgery. 8 eyes were re-challenged, of which 7 (87.5%) recurred. 7 case studies reported uveitis in 15 eyes of 10 patients. 7 of 15 eyes (46.7%) were either pseudophakic or aphakic. 6 eyes were re-challenged, and all 6 (100%) recurred.ConclusionsCases of uveitis or CME revealed a confounding effect of ocular surgery, aphakia or subluxed intraocular lens. PGAs may be used in non-surgical patients without concern of causing CME or uveitis. The incidences of PGA-associated CME and uveitis are rare with limited prospective studies on the cause-effect relationship.

Macular edema is a known side effect of taxane-based anticancer drugs. We retrospectively investigated data from 11 centers between January 2016 and December 2021. Among 14,260 patients, 30 (0.21%) developed macular edema; from these, the number of cases associated with nab-paclitaxel was 16 (0.43%), significantly higher than the number of cases associated with paclitaxel or docetaxel ( P  < 0.01). Visual acuity (VA) and retinal choroidal change were examined in 27 patients, with a follow-up of at least 3 months. The patients’ mean age was 67.2 years; 14 (51.3%) were male and four (14.8%) had unilateral onset. The mean interval between anticancer drug initiation and the first ophthalmology visit was 290.1 days. Among the 20 patients who discontinued anticancer drugs, VA and edema significantly improved 2 months after discontinuation (LogMAR VA: 0.50 vs. 0.28, central retinal thickness: 472.7 µm vs. 282.5 µm, both P  < 0.01). No significant changes were observed in the central choroidal thickness. A correlation was found between duration of taxane treatment and VA immediately before discontinuation of anticancer drugs ( β  = 0.00050; 95% confidence interval: 0.00036–0.00097; P  < 0.05). Although taxane-induced macular edema is reversible, slower anticancer drug discontinuation worsened VA, highlighting the need for regular ophthalmologic evaluation during treatments.

This case series reports on two patients who developed macular holes while on prostaglandin analogs (PGA) therapy. The first case involves a 63-year-old woman with a history of a macular hole of the left eye that had spontaneously closed. After starting PGA therapy for elevated intraocular pressure, cystoid macular edema formed, which resulted in reopening of the macular hole. The second case involves a 64-year-old man with primary open-angle glaucoma, on PGA therapy, with a newly diagnosed small macular hole of the right eye that closed after cessation of the PGA therapy. These cases demonstrate an association between prostaglandin analogs and the formation or reopening of full-thickness macular holes. [Ophthalmic Surg Lasers Imaging Retina 2024;55:XX–XX.]
