Mutton-fat keratic precipitates are associated with which type of anterior uveitis?

• A. Granulomatous
• B. Non-Granulomatous
• C. Hyphema-Related
• D. Viral Uveitis

Answer: (A)

Granulomatous anterior uveitis is characterized by large, greasy keratic precipitates—the mutton-fat deposits. These form from lipid-laden macrophages and epithelioid cells that accumulate on the corneal endothelium in chronic granulomatous inflammation. This appearance contrasts with non-granulomatous uveitis, where keratic precipitates are smaller and more fine, and with viral uveitis, which is typically non-granulomatous. So, the presence of mutton-fat keratic precipitates best indicates granulomatous anterior uveitis.
