Which retinal finding is a sign of neovascularization?

• A. Retinal hemorrhages
• B. Drusen
• C. Retinal tear
• D. Tortuous vessels

Answer: (D)

Neovascularization shows up as new, abnormal blood vessels growing in the retina. These vessels are typically fine, fragile, and follow irregular, winding paths rather than forming smooth, straight networks. That irregular, tortuous pattern is a classic clue that new vessels have formed in response to ischemia. So the presence of tortuous vessels directly signals neovascularization. Retinal hemorrhages can occur with neovascularization but aren’t specific markers. Drusen are deposits associated with age-related macular degeneration, not new vessel growth. A retinal tear is a mechanical break in the retina, not related to new vessel formation.
