Confocal Scan Features of Keratic Precipitates in Granulomatous versus

Purpose: to compare the morphologic features of keratic precipitates (kps) by confocal microscopy in granulomatous versus nongranulomatous noninfectious uveitis. methods: kp morphology was determined by confocal scan in patients with noninfectious granulomatous and noninfectious nongranulomatous uveitic cases. results: one hundred and twenty-seven eyes of 90 subjects with noninfectious uveitis were studied. thirty-nine eyes had granulomatous and 88 had nongranulomatous uveitis. smooth-rounded kps were significantly more common in the granulomatous subgroup (p < 0.001) while cruciform and dendritiform kps were more frequent in nongranulomatous uveitis (p < 0.001 and p < 0.005 respectively). conclusion: confocal scan may be used as an adjunctive tool for differentiating granulomatous from nongranulomatous uveitis. smooth-rounded kps are strongly suggestive of granulomatous inflammation
