What term means accidental, not at birth?

• A. Macular degeneration
• B. Adventitious
• C. Stargardt's disease
• D. Congenital

Answer: (B)

Adventitious refers to something that arises after birth, rather than being present from birth. In vision and disability contexts, using adventitious helps signal that the impairment was acquired later due to factors like injury or illness, not something the person was born with. That fits the idea of “accidental, not at birth.” The other terms describe different origins or timings: congenital means present at birth, Stargardt’s disease is a hereditary condition that typically shows up in childhood, and macular degeneration is a degenerative condition usually associated with aging. So adventitious is the best fit because it directly conveys late onset or acquisition after birth.
