title: The natural history of glaucoma and ocular hypertension after pediatric cataract surgery.
abstract: BACKGROUND
  We sought to define the prevalence and natural history of ocular hypertension and glaucoma for at least a 10-year period after pediatric cataract surgery.
  
  
  METHODS
  We conducted a prospective observational study of patients who received pediatric cataract surgery. Inclusion criteria included 2 directed ophthalmologic examinations performed at a minimum of 5 and 10 years after surgery.
  
  
  RESULTS
  A total of 63 patients (22 with bilateral cataracts and 41 with unilateral cataracts) were examined at a median of 15.1 year (range, 10.3-21.3 years) after surgery. A majority of the subjects had glaucoma or ocular hypertension (ie, 59%; 37/63). Nineteen percent (12/63) had glaucoma (5/22 with bilateral cataracts and 7/41 with unilateral cataracts). Approximately half (7/12) had developed glaucoma during the first 5-year observational period and the remainder (5/12) developed it during the following observational period. Forty percent (25/63) of the patients had ocular hypertension in at least one aphakic eye (9/23 with bilateral cataracts and 16/40 with unilateral cataracts). The rate of progression from ocular hypertension to glaucoma over a mean observational period of 7.2 years (range, 6.2-8.1 years) was 23% (5/22).
  
  
  CONCLUSIONS
  Patients who receive surgery for pediatric cataracts are at very high risk of developing ocular hypertension and glaucoma. Patients can develop late-onset glaucoma and ocular hypertension more than 10 years after surgery. Years of ocular hypertension may precede the diagnosis of late-onset glaucoma.
