Keratic precipitates

Inflammatory cellular accumulations, typically macrophages and epithelial cells, adherent to the posterior corneal surface/endothelium in chronic anterior segment inflammation such as uveitis. Possible causes are infection (HSV, HZV, syphilis, tuberculosis, toxoplasmosis), autoimmune disease (iridocyclitis/uveitis, sarcoidosis, Fuchs' heterochromic iridocyclitis, SLE, juvenile idiopathic arthritis), and trauma.
