Bilateral Iris Depigmentation and Ocular Hypotony as End-Stage Manifestations of Untreated Vogt-Koyanagi-Harada Disease.

PURPOSE: To describe severe bilateral iris depigmentation and persistent ocular hypotony as end-stage manifestations of untreated Vogt-Koyanagi-Harada disease.

METHODS: We present the clinical findings and diagnostic studies performed for three patients with bilateral iris depigmentation.

RESULTS: Vogt-Koyanagi-Harada disease in late recurrent stage was diagnosed in three patients with bilateral severe iris depigmentation and persistent ocular hypotony.

CONCLUSIONS: Early diagnosis and treatment of inflammation are crucial factors in the clinical outcome of Vogt-Koyanagi-Harada disease. When left undiagnosed and untreated from early stages, severe iris depigmentation and ocular hypotony, uncommon manifestations of this disease, can develop.
