Contributor: Lucas Lenci, MD

This is a 51-year-old female that presented with severe ocular pain and photophobia. She presented acutely and had evidence of mutton-fat keratic precipitates (KP) on exam. She was later diagnosed with sarcoidosis. KP are collections of inflammatory cells on the corneal endothelium. When these coalesce and become large with a yellowish color, they are described as mutton-fat KP. These are typically associated with granulomatous inflammation.
