Fuchs Heterochromic Iridocyclitis: Clinic, Diagnosis and Treatment

Fuchs heterochromic iridocyclitis (FHI) is a mild grade, chronic, non-granulamatous uveitis. Due to the asymptomatic course and variation of clinical findings, FHI is the uveitis with the highest number of late and wrong diagnosis. Decrased visual acuity related to floaters and cataract are the most frequent complains at presentation. It has characteristic features like unilateral involvement, diffuse, small stellate keratic precipitates, iris atrophy leading to heterochromia, abnormal angle vessels and lack of posterior syncheia or macular edema. Eventhough the etiology is still unknown, acquired rubella infection is the mostly approved. Visual prognosis is excellent in FHI. Cataract and glaucoma are among the major complications leading to visual loss. For the treatment steroids might be used for short term. Unnecessary long term use of steroids increases the risc for cataract and glaucoma.
