Choroidal Neovascularization: Understanding the Condition and Its Impact
Choroidal neovascularization (CNV) is a serious eye condition in which abnormal blood vessels begin to grow beneath the retina, specifically in the choroid layer. These vessels are fragile and prone to leaking blood or fluid, which disrupts normal retinal function. As a result, individuals with CNV may experience distortion of central vision, dark spots, and in severe cases, permanent vision loss if not treated promptly.

Over time, the center of the visual field may develop a blurred or darkened area. Many people initially dismiss these changes as minor vision fluctuations, but CNV progresses quickly, making early detection essential. Eye specialists often…
