Introduction: Children undergoing lens removal from birth to <13 years of age were enrolled into a clinical research registry. We describe the incidence of glaucoma/glaucoma suspect within 18 months of cataract surgery.
Methods: Data were collected from medical records at enrollment (<=45 days post-cataract surgery) and annually. We analyzed follow-up data <=18 months after first eye surgery. The primary outcome was development of glaucoma/glaucoma suspect (similar to the Infant Aphakia Treatment Study and international definitions [1, 2], and hereafter termed ‘glaucoma-related adverse events’).
Results: The overall incidence of glaucoma-related adverse events was 6.0% (95% confidence interval = 4.6 to 7.7) in 1101 eyes. There was a strong association between age at surgery and glaucoma-related adverse events; and presence of anterior segment (AS) abnormalities (cornea, iris, or anterior chamber abnormalities noted at surgery) and glaucoma-related adverse events. The adjusted glaucoma-related adverse event risk was 15.6% for 259 eyes <3 months of age versus 4.3% for 841 eyes >=3 months, P<0.001; and 11.7% for 161 eyes with AS abnormalities versus 5.7% for 928 eyes without, P=0.01.||Sex, race/ethnicity, axial length, laterality, intraocular lens implantation, anterior vitrectomy, and baseline intraocular pressure were not related to glaucoma-related adverse event development.
Discussion: Glaucoma-related adverse events occurred in a minority of eyes within 18 months of cataract surgery. Although very young age at surgery and the presence of AS abnormalities were strong predictors of glaucoma-related adverse events, these complications occurred in all enrolled age cohorts.
Conclusion: These data from a large registry lend support to findings of prior studies [2, 3], underlining the risk of glaucoma-related adverse events following cataract removal in early infancy.
