Which finding would you LEAST likely see in a patient with anterior uveitis caused by tuberculosis?

• A. Lisch Nodules
• B. Mutton-Fat KPs
• C. Koeppe Nodules
• D. Busacca Nodules

Answer: (A)

TB-related anterior uveitis is typically granulomatous. That means you’d expect large keratic precipitates on the corneal endothelium (often described as mutton-fat KPs) and iris nodules such as Koeppe nodules at the pupillary margin and Busacca nodules on the iris surface. Lisch nodules, in contrast, are iris hamartomas associated with neurofibromatosis type 1 and are not inflammatory signs of uveitis. They don’t arise from TB-related inflammation, so they are the least likely finding in this setting.
