A 38-year-old man presents with his third episode of acute monocular blurring over two years. Each episode resolves spontaneously within days. Examination during this episode shows markedly raised intraocular pressure of 42 mmHg, a few small keratic precipitates on the corneal endothelium, only trace anterior chamber cells, and a mid-dilated pupil. The diagnosis is:
- A Herpetic anterior uveitis with secondary glaucoma
- B Fuchs heterochromic iridocyclitis
- C Posner-Schlossman syndrome ✓
- D Pigment dispersion syndrome with acute pressure spike
Correct answer: C. Posner-Schlossman syndrome
Explanation
Posner-Schlossman syndrome, or glaucomatocyclitic crisis, features recurrent unilateral attacks of markedly elevated IOP with disproportionately mild anterior chamber inflammation and fine endothelial keratic precipitates, resolving spontaneously. Fuchs iridocyclitis is chronic with diffuse stellate KPs, heterochromia, and moderate pressure rise, not acute crises. Pigment dispersion shows a heavily pigmented trabecular meshwork and pigmentary KPs in a vertical spindle, not endothelial precipitates.
