title: Complications and prognostic factors in Vogt-Koyanagi-Harada disease.
abstract: OBJECTIVE
  To identify associations between complications of disease and final visual acuity in patients with Vogt-Koyanagi-Harada disease and to identify prognostic factors for disease outcome.
  
  
  METHODS
  All patients diagnosed with Vogt-Koyanagi-Harada disease at the Doheny Eye Institute or the Los Angeles County/University of Southern California Medical Center between 1983 and 1997 were reviewed. Data extracted included initial and final visual acuities, age, gender, ethnicity, complications, treatment, duration of disease, and number of recurrences.
  
  
  RESULTS
  One hundred one patients with Vogt-Koyanagi-Harada disease were identified, 68 (67%) of which were female. Mean age was 34 +/- 14 years (range, 8 to 75 years). Asians presented at a significantly older age than all other groups. One hundred three eyes (51%) developed at least one complication, including cataract in 84 eyes (42%), glaucoma in 54 eyes (27%), choroidal neovascular membranes in 22 eyes (11%), and subretinal fibrosis in 13 eyes (6%). Patients who developed at least one complication had a significantly longer median duration of disease and number of recurrent episodes of inflammation (P =.0001 for each) than did those patients who developed no complications. Statistically significant associations existed between poor final visual acuity and greater numbers of complications (P =.001), greater age at onset (P =.03), a longer median duration of disease (P =.03), and greater number of recurrent episodes of inflammation (P =.0004). Eyes possessing a better visual acuity at presentation were more likely to have a better visual acuity at final follow-up (P =.001).
  
  
  CONCLUSIONS
  Factors associated with a worse final acuity included increasing numbers of complications, greater age at onset, and worse acuity at presentation.
