Which condition involves breakdown or thinning of the macula leading to central vision loss?

• A. Hyperopia
• B. Analgesic
• C. Macular degeneration
• D. Retinitis pigmentosa

Answer: (C)

Central vision relies on the macula, the small retinal area that provides sharp detail for activities like reading and facial recognition. When the macula breaks down or thins, central vision deteriorates, while peripheral vision often remains. This pattern is characteristic of macular degeneration, which comes in two main forms: dry (atrophic) with gradual thinning and drusen deposits, and wet (neovascular) with abnormal vessels leaking fluid leading to more rapid vision loss. The other conditions don’t primarily affect the macula in this way: farsightedness (hyperopia) is about eye optics; analgesics are pain relievers; retinitis pigmentosa usually starts with peripheral vision loss and night blindness due to progressive retinal degeneration.
