Which statement about Stargardt's disease is true?

• A. Glaucoma
• B. It is juvenile macular degeneration
• C. Stargardt's disease
• D. CHARGE syndrome

Answer: (B)

Stargardt's disease is a juvenile form of macular degeneration. It is an inherited retinal dystrophy, usually due to ABCA4 gene mutations, that begins in childhood or adolescence and leads to degeneration of the macula with central vision loss while peripheral vision is often preserved early on. The underlying issue is the buildup of toxic material (lipofuscin) in the retinal pigment epithelium, which damages the cells responsible for sharp central vision. Clinically, this presents as blurred or distorted central vision, making tasks like reading difficult, with exam findings such as yellow-white flecks around the macula and progressive macular atrophy. This description fits Stargardt's disease more accurately than glaucoma (optic nerve issue often with elevated eye pressure and peripheral vision changes) or CHARGE syndrome (a broader congenital condition with multiple anomalies). So, the statement that Stargardt's disease is juvenile macular degeneration is the true characterization.
