title: Choroidal neovascularization in 36 eyes of children and adolescents.
abstract: OBJECTIVE
  To describe the clinical features and outcomes among eyes with choroidal neovascularization (CNV) in children and adolescents.
  
  
  METHODS
  A total of 36 eyes of 27 patients <18 years of age diagnosed with CNV between January 1978 and December 2008 were retrospectively reviewed. CNV was clinically diagnosed in all patients and its presence was confirmed by fundus fluorescein angiography (FFA). A total of 19 eyes underwent treatment. Anatomical outcome was evaluated as regressed/persistent/recurrent CNV. Snellen's values for best corrected visual acuity (BCVA) were converted to logMAR for statistical calculations.
  
  
  RESULTS
  Of the 27 patients, 17 (63%) were male. Nine (33.3%) of the 27 patients had bilateral CNV. At presentation, CNV was active in 22 (61.1%) eyes and regressed in 14 (28.9%) eyes. All active CNV cases were 'classic' type, with the majority (80.5%) being subfoveal. The mean greatest linear dimension (GLD) was 3.16 ± 1.94 mm (range, 0.9-10.15). The most common cause (41.7%) was post-inflammatory. The mean duration to regression in treated eyes was 103.53 days (15 eyes). Recurrence was noted in three (8.3%) eyes. The mean duration to first recurrence was 260 days (range, 90-390), and the mean follow-up duration was 779.53 ± 988.00 days.
  
  
  CONCLUSIONS
  CNV remains a cause of significant visual decline in children and adolescents. Male predominance, post-inflammatory etiology, bilateral affection, and subfoveal location are noteworthy, with a high regression rate in response to treatment. Re-treatment is required in a limited number of cases.
