Incidence and pre/post-treatment risk factors of glaucoma in Vogt-Koyanagi-Harada disease.

PURPOSE:To investigate the incidence and pre/post-treatment risk factors of glaucoma in patients with Vogt-Koyanagi-Harada (VKH) disease. METHODS:Data regarding secondary glaucoma were collected from the medical records of patients with VKH disease who were followed up at the uveitis service at Hiroshima University for more than 6 months. We examined the incidence of glaucoma and pre/post-treatment risk factors for glaucoma in patients with VKH disease. RESULTS:Forty-nine patients with VKH disease were included in this study (31 women and 18 men). The mean age at onset was 50.4 ± 15.4 years and the mean length of follow-up was 40.7 ± 25.5 months. The most common initial treatment was pulse intravenous corticosteroid therapy (89.8%). Fifteen patients developed secondary glaucoma during follow-up. The median time of glaucoma onset from VKH development was 4.5 months (range 0-44 months). Disc swelling type as a pre-treatment factor (p = 0.089, hazard ratio = 7.268), worse final best corrected visual acuity (p = 0.099, odds ratio = 1.545), and cataract progression (p = 0.076, odds ratio = 7.886) as post-treatment factors showed trends for glaucoma development. The patients who progressed to the chronic recurrent stage had more complications including glaucoma. CONCLUSION:Secondary glaucoma occurred in more than 30% of patients with VKH disease. The factors that showed a trend toward glaucoma development may reflect an association with delayed treatment initiation and prolonged ocular inflammation.
