Glaucoma following infantile cataract surgery

Abstract

Purpose: To examine incidence, risk factors, and outcomes of glaucoma following infantile cataract extraction.

Methods: A retrospective chart review of all patients who underwent cataract extraction between January 1, 1993, and December 31, 2006, at the Children's Medical Center in Dallas.

Results: Sixty-four eyes met inclusion criteria, of which 11 eyes (17.2%) developed glaucoma during a mean follow-up of 65.1 ± 4.3 months. Age younger than 3 months at cataract diagnosis (odds ratio 4.89, P = .05) or cataract extraction (odds ratio 4.4, P = .047) and the presence of anterior chamber anomalies (odds ratio 8.0, P = .01) were the only risk factors found to have statistical significance for the development of glaucoma. Eight of 11 eyes with glaucoma (72.2%) required at least one surgical intervention. Three of 10 eyes (30%) had a final best-corrected visual acuity below 20/400 and another 4 eyes (40%) demonstrated some degree of amblyopia.

Conclusion: Despite modern microsurgical techniques, infantile cataract surgery continues to pose a risk of secondary glaucoma. This was particularly true when cataract was diagnosed and/or extracted in patients younger than 3 months of age. Most eyes that developed glaucoma required surgical management and visual outcomes continue to be poor in this group.
