Neovascularization characterizes diabetic retinopathy and choroidal neovascularization associated with age-related macular degeneration, the most common causes of severe visual loss in the developed world. Gene transfer to the eye using adeno-associated viral (AAV) vectors is a promising new treatment for inherited and acquired ocular diseases. We used an AAV vector with rapid onset and high levels of gene expression in the retina to deliver three anti-angiogenic factors (pigment epithelium-derived factor, tissue inhibitor of metalloproteinase-3, and endostatin) to the eyes of mice in a mouse model of retinopathy of prematurity. All three vectors inhibited ischemia-induced neovascularization.

Background: Resistance to senescence in retinal pigment epithelial (RPE) cells can delay the progression of age-related macular degeneration (AMD). However, the mechanisms underlying RPE cell senescence remain inadequately understood, and effective therapeutic strategies are lacking. While astragaloside IV (Ast) has demonstrated anti-aging properties, its specific effects on RPE cell senescence and potential mechanisms are not yet fully clarified.

Autoimmune uveitis (AU) is a sight-threatening ocular autoimmune disorder that often manifests as retinal vasculitis. Increased neutrophil infiltration around retinal vessels has been reported during the progression of AU, while how they function is not fully recognized. Neutrophil extracellular traps (NETs), produced by activated neutrophils, have been suggested to be detrimental in autoimmune diseases.

Pathological neovascularization is a hallmark of many vision-threatening diseases. However, some patients exhibit poor responses to current anti-VEGF therapies due to resistance and limited efficacy. Recent studies have highlighted the roles of noncoding RNAs in various biological processes, paving the way for RNA-based therapeutics.

Purpose: The purpose of this study was to investigate the activated core kinases involved in the DNA damage responses (DDR) during ferroptosis of retinal pigment epithelial (RPE) cells in vitro and their regulatory effects on ferroptosis.

Methods: Ferroptosis was induced by erastin in induced RPE (iRPE) cells derived from human umbilical cord mesenchymal stem cells (hUCMSCs), hUCMSCs, and induced pluripotent stem cell-derived RPE (iPSC-RPE) cells. CCK8 was employed to measure the cell viability.

Colour vision defects (CVDs) can be both congenital and acquired, with acquired dyschromatopsia often associated with medication toxicity. This review explores various standardised colour vision tests used to detect these defects, including the Ishihara plate test, Farnsworth-Munsell 100 hue test, and anomaloscopes. These methods are evaluated for their effectiveness in diagnosing CVDs, particularly in acquired conditions.
