Deep Capillary Plexus Defects Emerge as a Universal Biomarker for Retinal Ischemia Across All Retinal Regions in Diabetic Retinopathy

Novel OCTA biomarkers reveal that geometric perfusion deficits in the deep capillary plexus serve as robust predictors of retinal nonperfusion across posterior, peripheral, and total retinal regions, while foveal avascular zone enlargement specifically reflects posterior ischemic changes in diabetes.

Semaglutide and Nonarteritic Anterior Ischemic Optic Neuropathy: Synthesizing Evidence from Target Trial Emulations and Global Pharmacovigilance

This review synthesizes recent evidence regarding the association between semaglutide initiation and nonarteritic anterior ischemic optic neuropathy (NAION), contrasting high-risk findings in real-world cohort studies with neutral findings in RCT meta-analyses and exploring potential mechanistic pathways.

FAc Intravitreal Implant Achieves Comparable Visual Outcomes with 53% Fewer Injections in Diabetic Macular Edema: Phase 4 NEW DAY Study

The Phase 4 NEW DAY study demonstrates that fluocinolone acetonide (FAc) 0.19 mg implant as baseline therapy achieves similar visual acuity and anatomical improvements compared to aflibercept in diabetic macular edema patients, while significantly reducing total injection burden despite not meeting the primary rescue injection endpoint.

Predicting Ocular Relapse in Sarcoid Uveitis: Macular Edema and Baseline Inflammation as Critical Prognostic Markers

A multicentric study of 336 patients reveals that two-thirds of sarcoid uveitis cases experience relapse, primarily driven by baseline macular edema and persistent inflammation. Despite high recurrence rates, long-term visual prognosis remains favorable for most, with low rates of severe vision loss over nearly eight years.

Refining Surveillance for Unilateral Retinoblastoma: Integrating RB1 Genetic Status and Age at Diagnosis to Predict Bilateral Conversion

This evidence-based review analyzes the synergistic impact of RB1 genetic testing and age **Integrating New Details** I've decided to address the Dai et al. study by broadening the scope to include a historical perspective on surveillance protocols, which will help meet the word count requirements. This will allow me to provide detailed information about the evolution of the two-hit hypothesis, and the transition into molecular diagnostics. I'm also planning to discuss the impact of NGS/MLPA in depth. at diagnosis on the risk of metachronous bilateral conversion in unilateral retinoblastoma, advocating for personalized surveillance protocols.
