What are the 'sparkles' seen in hypermature cataracts?

• A. Crystalline deposits
• B. Calcium oxalate crystals
• C. Protein aggregates
• D. Retinal pigment changes

Answer: (C)

The sparkles seen in hypermature cataracts come from refractile protein aggregates inside the lens. As the lens ages, its crystallin proteins clump together, forming tiny, highly reflective particles. In a hypermature cataract the cortex may liquefy and these protein clusters become more concentrated, scattering and reflecting light so they appear as glittering specks. Mineral crystals, such as calcium oxalate, would indicate mineral deposits—not the typical cause of the glittering seen in cataracts. Retinal pigment changes are in the retina, not the lens, so they don’t explain the sparkles in the lens tissue.
