Purpose: To evaluate the 3-year outcomes of VEGF inhibitors in the treatment of cystoid macular edema due to branch retinal vein occlusion (BRVO) in an international multicenter cohort of eyes.
Design: Multicenter, international, BRVO database study.
Subjects: Seven hundred forty-seven patients (760 eyes) undergoing intravitreal therapy for BRVO for 3 years in a multicenter international setting.
Methods: Demographics, visual acuity (VA) in logarithm of the minimum angle of resolution letters, central subfield thickness (CST), treatments, number of injections, and visits data was collected using a validated web-based tool.
Main Outcome Measures: Visual acuity gain at 3 years in logarithm of the minimum angle of resolution letters. Secondary outcome measures included anatomical results, treatment pattern, and percentage of completers. A subgroup analysis by study drug was conducted for clinical outcomes.
Results: Mean adjusted VA change was +11 letters (95% confidence interval 9-13), mean adjusted change in CST was -176 μm (-193, -159). Median number of injections/visits was 16 of 24 at 3 years of follow-up. Most eyes received VEGF inhibitors exclusively (89%, n = 677) and as a monotherapy in 71% (n = 538). Few eyes were switched to steroids (11%, n = 83). Suspensions in treatment >180 days occurred in 26% of study eyes. Aflibercept showed greater CST reductions (-147 vs. -128 vs. -114 μm; P < 0.001) and significantly lower switching rates (14% vs. 38% vs. 33%; P < 0.001) compared with ranibizumab and bevacizumab, respectively.
Conclusions: This international study of 3-year BRVO outcomes after starting treatment with VEGF inhibitors found adequate visual and anatomical results in routine clinical care. Visual outcomes were similar among the different initiating VEGF inhibitors, although eyes starting with aflibercept had better anatomical outcomes and a lower switching rate.

Background: Intravitreal anti-vascular endothelial growth factor (VEGF) treatment for diabetic macular oedema (DME) may begin with several initial monthly doses. Characteristics, treatment patterns and outcomes were compared for eyes with DME that did and did not receive such initial doses.
Methods: This was a retrospective database study using American Academy of Ophthalmology Intelligent Research in Sight Registry data (01/01/15-31/12/20; index period).

Immunotherapy is one of the research hotspots in colorectal cancer field in recent years. The colorectal cancer patients with mismatch repair-deficient (dMMR) or high microsatellite instability (MSI-H) are the primary beneficiaries of immunotherapy. However, the vast majority of colorectal cancers are mismatch repair proficient (pMMR) or microsatellite stability (MSS), and their immune microenvironment is characterized by "cold tumors" that are generally insensitive to single immunotherapy based on immune checkpoint inhibitors (ICIs).

Our current prospective cross-sectional study aimed to investigate the effect of anti-vascular endothelial growth factor (VEGF) drugs used in the treatment of retinopathy of prematurity on retinal maturation and persistent avascular retina (PAR). Retinal imaging was performed with Optos confocal laser ophthalmoscopy for 100 patients aged 4 to 8 years who were screened and treated for retinopathy of prematurity (ROP) during the neonatal period. The ROP examination findings (stage and zone) and treatment history (age in weeks at time of treatment and anti-VEGF drug used) from the neonatal period were reviewed.

Background: We aimed to describe a 2-year outcome of eyes managed by practitioners benchmarked using a funnel plot by their frequency of treatment using vascular endothelial growth factor (VEGF) inhibitors for naive retinal vein occlusion (RVO).
Methods: A multicentre, international, observational study of 29 doctors in 12 countries managing 1110 eyes with RVO commencing VEGF inhibitors between 1 January 2012-2022 tracked in the Fight Retinal Blindness! registry.
Results: We identified 3 outlying 'intensive' practitioners (managing 350/1110 eyes [32%]), 22 'typical' practitioners (604/1110, [54%]) and 4 outlying 'relaxed' practitioners (156/1110, [14%]) with respective 24-month outcomes in Branch and Central RVO including the primary outcome, mean adjusted change in visual acuity (VA) in BRVO: +16.
