The development of glaucoma, or glaucoma suspect, is common in children 5 years after cataract surgery, according to research published in JAMA Ophthalmology. Secondary findings also revealed a modest myopic shift for pseudophakic children during the same time period.

Researchers enrolled 994 children (median age 3.6 years, 51% boys, 1268 eyes) who underwent cataract surgery between 2012 and 2015 in a multi-center, prospective cohort study. They reviewed patient records yearly for five years to assess surgical and visual outcomes. Among participants, 43% underwent bilateral surgery and 59% of eyes received an intraocular lens.

Researchers included 701 eyes at 5 year follow-up after considering eyes with available visual acuity (VA) data. Median VA was 20/63 for bilateral aphakic eyes (58%), 20/32 for bilateral pseudophakic eyes (54%), 20/200 for unilateral aphakic eyes (61%), and 20/65 for unilateral pseudophakic eyes (51%). Participants achieved age-normal VA in 20% (n=37, 95% CI, 13-27%), 42% (n=88, 95% CI, 34-50%) 12% (n=15, 95% CI, 7-19%), and 18% (n=34, 95% CI, 13-25%) of eyes, respectively.

The median change in spherical equivalent (SE) refractive error was −8.38 D for bilateral aphakic eyes, −1.63 D for bilateral pseudophakic eyes, −10.75 D for unilateral aphakic eyes, and −1.94 D for unilateral pseudophakic eyes at 5 year follow-up. Researchers noted a general myopic shift within 45 days of surgery among all subgroups.

A total of 14% of children with no preoperative trauma or diagnosis experienced glaucoma-related adverse events. The 5 year cumulative occurrence of glaucoma was 46% (95% CI, 28-59%) among bilateral aphakic eyes, 7% (95% CI, 1-12%) among bilateral pseudophakic eyes, 25% (95% CI, 15-34%) among unilateral aphakic eyes, and 17% (95% CI, 5-28%) among unilateral pseudophakic eyes.

“Although good VA was possible after cataract surgery in children from birth to less than 13 years of age, age-normal vision was uncommon,” according to the investigators. “Amblyopia was frequent, and the risk for development of glaucoma increased during the first 5 years after cataract surgery.”

This study was limited by a high dropout rate and the exclusion of children who were unable to perform letter optotypes from VA analysis.
