Sarcoid uveitis was diagnosed by characteristic ocular signs of sarcoidosis based on the International Workshop on Ocular Sarcoidosis (IWOS) guidelines of 2009 [14]: (1) mutton-fat keratic precipitates and iris nodules; (2) nodules in the trabecular meshwork and tent-shaped peripheral anterior synechia; (3) snowball or string-of-pearls vitreous opacities; (4) nodular periphlebitis; (5) multiple chorioretinal lesions; (6) optic disc nodule(s)/granuloma(s) and/or solitary choroidal nodule; and (7) bilaterality.
(5) The most common ocular manifestation is uveitis, with the posterior form being more common than the anterior form, the latter of which normally appears as an iridocyclitis associated with classic, granulomatous, mutton-fat keratic precipitates, hypopyon and posterior synechiae.
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.
Initial examination showed an isolated vascular tumor of the iris and ciliary body with anterior uveitis and mutton-fat keratic precipitates, suggesting the diagnosis of a granulomatous disease.
