Keratic Precipitates

Keratic Precipitates (KPs) 

  • 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.
