How does nuclear sclerosis appear on exam?

• A. Blue-gray central haze
• B. Clear lens
• C. Yellow peripheral specks
• D. Cloudy cornea

Answer: (A)

Nuclear sclerosis is an age-related hardening and opacification of the lens nucleus. On slit-lamp examination, you see a central, dense opacity within the nucleus that often takes on a blue-gray tint. This central haze reflects the increased density and light scattering of the aging lens fibers, giving that characteristic bluish appearance, especially with certain illumination settings. As the opacity progresses, the nucleus may yellow or brown, but the typical exam finding early on is that central blue-gray hue. The other options don’t fit because a clear lens would show no opacity, yellow peripheral specks point to cortical changes rather than the nucleus, and a cloudy cornea is a corneal issue, not a lens problem.
