medium · MCQ · Q-CDDEC8
A 35-year-old male presents with recurrent episodes of painful granulomatous anterior uveitis in the right eye, accompanied by mutton-fat keratic precipitates, iris heterochromia (hypochromia of the affected eye), and cataract. Vitritis with 'snowball' opacities is also noted. What is the most likely diagnosis?
- A.Fuchs heterochromic iridocyclitis
- B.Posner-Schlossman syndrome
- C.Herpetic iridocyclitis
- D.SarcoidosisCorrect answer
Solution
Mutton-fat keratic precipitates, painful recurrent granulomatous anterior uveitis, iris heterochromia (though Fuchs typically has non-granulomatous uveitis, fine KP, and iris hypochromia without pain), vitritis, and snowball opacities strongly point towards a granulomatous etiology such as Sarcoidosis or tuberculosis. Fuchs heterochromic iridocyclitis is typically asymptomatic, non-granulomatous, and lacks posterior synechiae. Here, the presence of pain, mutton-fat KPs, and vitritis rules out Fuchs.
