Correct answer: E — Panuveitis

The combination of anterior uveitis features (keratic precipitates, posterior synechiae), intermediate features (vitreous cells), and posterior involvement constitutes panuveitis. Sarcoidosis is a classic cause of panuveitis (also anterior, intermediate, or posterior alone). Other causes include Behçet's disease, Vogt-Koyanagi-Harada disease, and syphilis. Granulomatous uveitis with mutton-fat KP is characteristic of sarcoidosis, TB, and syphilis. Management requires systemic corticosteroids and steroid-sparing immunosuppression.
