Abstract
Purpose
We evaluated the long-term visual outcomes in children with primary congenital glaucoma and determined the factors associated with the final visual outcomes.
Methods
Medical records of children with primary congenital glaucoma between 2005 and 2016, seen at Seoul National University Children’s Hospital in South Korea, were reviewed. The minimum follow-up period after surgery for primary congenital glaucoma was 3 years. Visual acuity (VA) was categorized into good (≧20/70) and poor (< 20/70). Factors including age, VA, refractive errors, intraocular pressure (IOP), laterality, and cup-to-disc (C/D) ratio were compared between the groups.
Results
A total of 71 eyes of 44 patients were included. The patients’ age at the time of surgery was 14.7 ± 12.2 months. The mean IOP was 28.3 ± 7.0 mmHg. During 6.7 ± 2.7 years of mean follow-up after surgery, 39 eyes (54.9%) needed occlusion treatment. After occlusion, patients with lower IOP values, lesser additional surgeries, reversal of optic disc cupping, and better initially measured VA achieved a better visual outcome. At the final assessment, the mean age was 7.8 ± 2.6 years, and the mean VA gain was 15.0 ± 19.4 letters. There were 44 eyes (62.0%) with VA ≧20/70.
Conclusions
In children with primary congenital glaucoma, IOP control and the optic disc configuration over time are important factors associated with visual outcome. Regular follow-up and correction of refractive errors—along with occlusion for those with difference in VA between the two eyes—might be helpful for achieving better visual outcomes.
