Significant prognostic factors for Vogt-Koyanagi-Harada disease in the early stage.

This study identified possible prognostic signs in the acute stage of Vogt-Koyanagi-Harada (VKH) disease in a retrospective chart review of all patients diagnosed with VKH disease between 1991 and 2001. Those who were diagnosed more than 1 month after the onset of ocular symptoms were excluded. Data recorded included age, sex, clinical features, systemic manifestations, recurrence, treatment, complications, and final visual acuity. Exudative retinal detachment was ranked into 3 grades (grade 1: within peripapillary 3 disc diameters and arcade; grade 2: larger than grade 1 but no inferior retinal detachment; grade 3: inferior or total retinal detachment). Of the 31 patients, 19 were males and 12 were females. Mean age at presentation was 38.55 +/- 10.63 years. The mean follow-up period was 33.09 months. Extraocular manifestations were present in 17 cases. Four patients had at least one complication, including cataract in seven eyes and glaucoma in one eye. Forty-nine eyes (79%) had a final visual acuity of 6/12 or better. Final visual acuity was significantly better in younger patients (p = 0.023) and those who had less extensive retinal detachment (p = 0.006), no pigmentary change (p = 0.008) and no complications (p = 0.030). The visual prognosis of VKH disease is variable, though generally favorable. In the acute stage, the extent of retinal detachment may be an important risk factor for visual outcome. Further study of this factor as an indicator for treatment is necessary.
