Behcet's disease-associated uveitis is classified as which type, and which feature on slit-lamp examination is considered pathognomonic of its acute attacks?
- A Posterior uveitis; Dalen-Fuchs nodules
- B Panuveitis; non-granulomatous hypopyon that shifts with head position ✓
- C Anterior uveitis; mutton-fat keratic precipitates
- D Intermediate uveitis; snowbanking at the pars plana
Correct answer: B. Panuveitis; non-granulomatous hypopyon that shifts with head position
Explanation
Behcet's disease causes a severe, recurrent, non-granulomatous panuveitis. Its hallmark acute feature is a hypopyon uveitis where the hypopyon is mobile — it shifts with changes in head position because it is composed of fibrin-poor, predominantly cellular exudate. Dalen-Fuchs nodules are seen in sympathetic ophthalmia and VKH. Mutton-fat KPs indicate granulomatous uveitis (sarcoidosis, TB). Snowbanking characterizes intermediate uveitis/pars planitis.
