Age-related macular degeneration is the leading cause of blindness and visual impairment in the developed world. The recently introduced anti-vascular endothelial growth factor (VEGF) intravitreal injections of Ranibizumab (Lucentis) and Bevacizumab (Avastin) generated a heated academic argument: on the one hand Lucentis is the only drug that was proven effective and relatively safe in large prospective double-blinded studies, albeit this drug is expensive and might cost up to $1000 per single injection. On the other hand, Avastin is widely used worldwide as a low cost alternative for Lucentis, with an estimated cost of about $120 per injection, although its efficacy and side effects were investigated only in smaller retrospective studies. The ophthalmic community still lacks definite information regarding which is the preferred drug, and awaits the results of a large prospective study comparing the two drugs.

Faculty of Medicine, University Vita-Salute San Raffaele, Milan, Italy.
Background: Glaucoma, diabetic retinopathy, and age-related macular degeneration impose substantial economic burdens on healthcare systems due to their high prevalence and chronic nature. Nevertheless, comprehensive Italian data is limited. This study aims to collect Italian evidence on the economic impact of these conditions to support more effective healthcare planning.

Purpose: Intravitreal injections of anti-VEGF agents are considered as safe, with a very low rate of intraocular inflammations (IOI). Faricimab is a novel intravitreal bispecific antibody targeting both VEGF-A and angiopoietin-Tie2 independently. Despite a safe profile in randomized clinical trials, several real-life studies have reported cases of IOI.

Numerous diseases, such as diabetic retinopathy and age-related macular degeneration, can lead to retinal neovascularization, which can seriously impair the visual function and potentially result in blindness. The presence of the blood-retina barrier makes it challenging for ocularly administered drugs to penetrate physiological barriers and reach the ocular posterior segments, including the retina and choroid. Herein, we developed an innovative bifunctional peptide, Tat-C-RP7, which exhibits excellent penetration capabilities and antiangiogenic properties aimed at treating retinal neovascularization diseases.

The aim of dynamic prediction is to provide individualized risk predictions over time, which are updated as new data become available. In pursuit of constructing a dynamic prediction model for a progressive eye disorder, age-related macular degeneration (AMD), we propose a time-dependent Cox survival neural network (tdCoxSNN) to predict its progression using longitudinal fundus images. tdCoxSNN builds upon the time-dependent Cox model by utilizing a neural network to capture the nonlinear effect of time-dependent covariates on the survival outcome.
