What is a hallmark fundoscopic sign of AMD?

• A. Drusen
• B. Geographic atrophy
• C. Metamorphopsia
• D. Retinal hemorrhage

Answer: (A)

Drusen are the hallmark fundoscopic signs of age-related macular degeneration. They are yellow-white extracellular deposits that accumulate between the retinal pigment epithelium and Bruch’s membrane. Their presence in the macula—especially soft, confluent drusen with pigmentary changes—tracks with AMD, reflecting early to intermediate dry AMD and signaling risk for progression to advanced forms. Metamorphopsia is a subjective distortion patients report, not a specific fundoscopic sign. Retinal hemorrhage can occur with neovascular (wet) AMD or other conditions, but it is not the defining sign of AMD. Geographic atrophy represents an advanced stage of dry AMD, not the initial hallmark finding.
