A 55-year-old chronic steroid user complains of glare, difficulty reading in bright light, and rapid deterioration of near vision over the past few months. Slit-lamp examination reveals a plaque-like opacity just in front of the posterior capsule in the visual axis. What type of cataract is this?
- A.Nuclear sclerotic cataract
- B.Cortical cataract
- C.Posterior subcapsular cataractCorrect answer
- D.Lamellar cataract
Solution
Posterior subcapsular cataracts (PSC) lie directly in the visual axis and nodal point of the eye, causing disproportionate glare and near-vision impairment, especially under bright illumination (miosis). They are classically associated with long-term systemic or topical corticosteroid therapy and chronic inflammation.
