The tapetal reflection remains visible during which stage?

• A. Mature cataract
• B. Incipient cataract
• C. Hypermature cataract
• D. Immature cataract (correct)

Answer: (D)

Tapetal reflection depends on lens clarity. The retina’s reflectivity can still be seen when parts of the lens remain transparent. In the immature cataract stage, there are opacities but enough clear lens tissue is left for light to pass through and reflect back from the tapetum, so the tapetal reflex is still visible. As the cataract becomes mature or hypermature, the lens becomes fully opaque or liquefies, blocking light entirely and eliminating the reflex.
