Neovascularization in the eye is primarily caused by conditions that lead to hypoxia or insufficient oxygen supply to retinal tissues, such as diabetic retinopathy, age-related macular degeneration, and retinal vein occlusion. In response to low oxygen levels, the body releases vascular endothelial growth factor (VEGF), which stimulates the growth of new, often abnormal blood vessels. These new vessels can leak fluid and bleed, leading to vision impairment. Additionally, inflammation and other factors can contribute to the process of neovascularization.
