Keratic Precipitates
- Cellular deposits on the corneal endothelium.
- Acute, fresh KPs tend to be white and round, while old KPs are usually irregular, faded and pigmented.
- Mutton-fat KP: large, greasy-white KPs (approximately 1 mm in diameter), which represent clusters of macrophages and epithelioid cells. Typically occur in granulomatous uveitis.
