Senescent retinal pigment epithelial cells play a key role in neovascular age-related macular degeneration (nAMD); however, the mechanisms underlying the angiogenic ability of these cells remain unclear. Herein, we investigated the effects of the senescent adult retinal pigment epithelial cell line-19 (ARPE-19) on wound healing, cell migration and survival, and tube formation abilities of human umbilical vein endothelial cells (HUVECs). Additionally, we used Brown Norway rats to establish a laser-induced choroidal neovascularization (CNV) model for further nAMD-related studies.

Functional cell death pathways are essential for normal ocular vascular development and tissue homeostasis. As our understanding of necrosis-based cell death pathways has expanded, the inclusion of regulated forms, including necroptosis, ferroptosis, and oxytosis, has occurred. Although the existence of these pathways is well described, our understanding of their role during vascular development and pathological neovascularization is very limited.

To evaluate the outcomes and predictive factors for fluid resolution following three loading injections of faricimab for neovascular age-related macular degeneration(AMD). This retrospective study included patients diagnosed with treatment-naïve neovascular AMD who received three monthly injections of faricimab. Changes in best-corrected visual acuity(BCVA) and central retinal thickness(CRT) following treatment were evaluated.

Reduction-oxidation factor-1 or apurinic/apyrimidinic endonuclease 1 (Ref-1/APE1) is a crucial redox-sensitive activator of transcription factors such as NF-κB, HIF-1α, STAT-3 and others. It could contribute to key features of ocular neovascularization including inflammation and angiogenesis; these underlie diseases like neovascular age-related macular degeneration (nAMD). We previously revealed a role for Ref-1 in the growth of ocular endothelial cells and in choroidal neovascularization (CNV).

This study aimed to evaluate the changes in cytokine levels in the aqueous humor and factors of treatment resistance following intravitreal faricimab injection in treatment-naïve patients with neovascular age-related macular degeneration. A total of 32 eyes were analyzed before and after a single faricimab injection. Although the best-corrected visual acuity (BCVA) showed no significant improvement, the mean central retinal thickness decreased significantly by 73.
