Which term describes the growth of new blood vessels on the retina?

• A. Amblyopia
• B. Drusen
• C. Macular degeneration
• D. Neovascularization

Answer: (D)

Neovascularization is the growth of new blood vessels on the retina. This process often signals pathology in the eye, as seen in conditions like proliferative diabetic retinopathy or wet age-related macular degeneration, where the fragile new vessels can bleed or form scar tissue that distorts or destroys vision. The other terms refer to different concepts: amblyopia is reduced vision from brain suppression of input from one eye, drusen are yellow deposits under the retina associated with age-related macular degeneration, and macular degeneration is a disease process that can involve new vessels but is defined by central vision loss and other retinal changes rather than the vessel growth itself.
