Vogt-Koyanagi-Harada disease during prolonged intermittent steroid therapy for chronic obstructive pulmonary disease: a case report.

Vogt-Koyanagi-Harada Disease (VKHD) is a rare systemic granulomatous autoimmune condition that affects melanocyte-rich organs including the eyes, inner ears, meninges, skin, and hair. VKHD causes chronic uveal inflammation and a loss in visual acuity in some patients. Patients generally respond well to steroid therapy. In our patient, we evidenced VKHD in the chronic recurrent stage at the time of presentation while the patient was on intermittent systemic steroid therapy. To date, no cases of VKHD have been reported in patients who were taking immunosuppressive medications. This study sheds light on the possibility that, in addition to the complex multisystem autoimmune phenomenon, other variable factors may also be implicated in the etiopathogenesis of this disease. Also, if a patient presents with subacute vision loss and an acute onset headache and encephalopathy, this differential diagnosis should be kept in mind, and the patient should be treated as soon as possible if the diagnosis is confirmed.
