What ocular condition involves abnormal growth of blood vessels in the retina?

Choroidal neovascularization refers to the growth of new blood vessels from the choroid (the layer of blood vessels and connective tissue beneath the retina) into the retina itself. This abnormal growth often leads to leakage and bleeding, which can cause significant vision loss and is commonly associated with conditions such as age-related macular degeneration (AMD) and other retinal diseases. The presence of these new vessels can disrupt the retinal structure and function, resulting in symptoms such as blurred or distorted vision.

This condition is particularly concerning because it may require prompt treatment to prevent irreversible damage to the retina and preserve vision. Treatments may include anti-VEGF (vascular endothelial growth factor) injections, photodynamic therapy, or laser surgery, aimed at managing the neovascularization and its effects.

In contrast, cataracts involve the clouding of the lens in the eye and are unrelated to blood vessel growth in the retina. Retinal detachment is the separation of the retina from the underlying tissue, which can cause vision loss but does not directly involve the abnormal growth of blood vessels. Macular degeneration, while it can involve choroidal neovascularization, is a broader term that signifies the overall degeneration of the macular region of the retina, including changes in pigmentation and
