Which feature is present in immature cataracts?

• A. Tapetal reflection still visible (correct)
• B. Tapetal reflection absent
• C. Lens capsule wrinkling
• D. Protein precipitation

Answer: (A)

In cataract assessment, the key idea is how much light can still reach the retina. In an immature cataract, the lens isn’t fully opaque, so enough light passes through to preserve the red reflex, or tapetal reflection, from the retina. That means you can still see the tapetal reflection during examination. As the cataract progresses toward maturity, the lens becomes dense enough to block light from reaching the retina, and the tapetal reflection disappears. So the presence of the tapetal reflection indicates an immature stage. If the tapetal reflection were absent, that would suggest a more advanced, mature cataract. Lens capsule wrinkling tends to occur in hypermature changes when the capsule shrinks and folds, not in immature cataracts. Protein precipitation happens as part of cataract formation in general, but it’s not a defining feature that distinguishes immature from the later stages.
