Fuchs Heterochromic Iridocyclitis: Clinic, Diagnosis, and Treatment

Abstract

Fuchs heterochromic iridocyclitis (FHI) is a mild grade, chronic, non-granulomatous uveitis. Due to the asymptomatic course and variation of clinical findings, FHI is the uveitis with the highest number of late and wrong diagnosis. Decreased visual acuity due to floaters and cataracts are the most frequent complaints 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 synechia or macular edema. Etiology is still uncertain however acquired rubella infection is the most 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 the short term. Unnecessary long term use of steroids increases the risk for cataract and glaucoma
