What is nuclear sclerosis?

• A. Age-related optical change of the lens nucleus
• B. A type of glaucoma
• C. A retinal detachment
• D. A cataract type

Answer: (A)

Nuclear sclerosis is an aging-related change in the lens, specifically the central nucleus. Over time, the proteins in the nucleus become denser and the fibers shorten, causing the nucleus to harden (sclerosis) and often take on a yellowish color. This alters the lens’s optical properties and can lead to a mild refractive shift or gradual blur, reflecting a normal aging process of the lens rather than a separate disease. It’s not related to glaucoma, retinal detachment, or other retinal conditions, and while it can be described as part of senile cataract development, the key idea is the age-driven hardening and color change of the lens nucleus.
