Inflammatory cells on the corneal endothelium.

keratic precipitates (KP)

Cells (e.g. leukocytes) deposited on the endothelium of the cornea which occur as a result of inflammation of the iris or the ciliary body. They often collect in a triangular pattern with the base down (Arlt's triangle) on the inferior portion of the endothelial surface. They may also be distributed diffusely over the endothelium, as in Fuchs' heterochromic iridocyclitis or anterior uveitis, or concentrated in one area, as in disciform keratitis or herpes simplex keratitis. In granulomatous uveitis they are larger than in nongranulomatous uveitis, greasy in appearance (called 'mutton fat'). Following treatment of the primary cause they usually disappear. See cornea guttata.

(8) It can present between 20-50 years of age and with recurring episodes; one will observe keratic precipitates on the corneal endothelium.
On biomicroscopic examination, both eyes showed injected conjunctiva, corneal white ring infiltrates that matched the contours of corneal epithelial defects, white fluffy keratic precipitates, and normal appearing iris and lens (Figure 5).
White fluffy keratic precipitates and hypopyon can be seen at this stage.
Slit-lamp examination revealed diffuse large mutton-fat keratic precipitates (KPs) and a line which was parallel to the limbus in the peripheral corneal endothelium developed from KPs.
