The World Ophthalmology Congress (WOC) is one of the largest international ophthalmology conferences, taking place every two years. The event this year was the first of its kind, held as a virtual summit due to the Covid-19 pandemic. There were over 2000 talks from world experts, a virtual industry exhibition including free papers, e-posters, live symposia and presentations. Medical retina is a subspecialty in which exciting and innovative advances in research were presented. The topics covered included the use of Conbercept for Polypoidal Choroidal Vasculopathy, Faricimab in Diabetic Macular Oedema and neovascular Age Related Macular Degeneration (nAMD), Brolucizumab, Aflibercept and Port Delivery Systems in nAMD, amongst many others. Medical retina continues to be a rapidly advancing field within ophthalmology with new research findings having great implications for treatment burden and service delivery. This report summaries the highlights of advances within the medical retina subspecialty from free papers in WOC 2020.

Abstract Background Polypoidal choroidal vasculopathy (PCV) is a type of age-related macular degeneration that can cause permanent vision loss. The purpose of this paper was to report the one-year outcomes of fixed-dosing aflibercept therapy for the treatment of PCV. Methods This was a prospective, single-arm, interventional case series study of 25 PCV patients; 12 pre-treated and 13 treatment-naïve patients. The patients were treated and monitored for 12 months. Each patient was administered with an aflibercept (2.0 mg) injection every month for the first 3 months (the loading phase), and thereafter, once every 2 months. At every follow-up visit, best-corrected visual acuity (BCVA) test, fundus examination, and optical coherence tomography for measuring the central subfield macular thickness (CSMT) were performed. Fluorescein and indocyanine green angiography were conducted at baseline and at 4 and 12 months. Results After 12 months of aflibercept therapy, the mean BCVA of the patients significantly improved from 65.48 letters at baseline to 69.91 letters (p=0.001), and the CSMT significantly decreased from 406.92 um at baseline to 276.12 um (p< 0.001). Additionally, ten patients (40%) showed complete polyp regression. The treatment-naïve patients showed a statistically significant improvement in BCVA from 66.58 letters at baseline to 76.36 letters at 12 months, and a significant decrease in CSMT, from 462 to 243 um. In the pre-treated group, there was no change in BCVA (64.46 letters), and the decrease in CSMT from 356.08 to 303.69 um was not statistically significant. Conclusions The fixed-dosing aflibercept regimen is effective for treating patients with PCV and is more effective in treatment-naïve patients than in pre-treated patients.

Intravitreal antivascular endothelial growth factor (VEGF) agents are widely used to treat ocular conditions but the benefits and harms of these treatments are uncertain. We conducted a systematic review to compare the effects of aflibercept, bevacizumab and ranibizumab on best-corrected visual acuity (BCVA) changes, quality of life and ocular or systemic adverse events in patients with neovascular age-related macular degeneration (NVAMD), diabetic macular oedema (DME) and central or branch retinal vein occlusion (RVO). We searched published and unpublished literature sources to February 2017 for randomised controlled trials and cohort or modelling studies reporting comparative costs in the USA. Two reviewers extracted data and graded the strength of the evidence using established methods. Of 17 included trials, none reported a clinically important difference (≥ 5 letters) in visual acuity gains between agents. Nine trials provide high-strength evidence of no difference between bevacizumab and ranibizumab for NVAMD. Three trials provide moderate-strength evidence of no difference between bevacizumab and ranibizumab for DME. There was low-strength evidence of similar effects between aflibercept and ranibizumab for NVAMD, aflibercept and bevacizumab for RVO and all three agents for DME. There was insufficient evidence to compare bevacizumab and ranibizumab for RVO. Rates of ocular adverse events were low, and systemic harms were generally similar between groups, although 1 DME trial reported more arterial thrombotic events with ranibizumab versus aflibercept. Overall, no agent had a clear advantage over another for effectiveness or safety. Aflibercept and ranibizumab were significantly less cost-effective than repackaged bevacizumab in two trials. Systematic review registration number: CRD42016034076.
