Prcis: Glaucoma after pediatric cataract surgery is common and challenging. Age at surgery and the presence of microcornea or other anterior segment (AS) abnormalities can be used to identify those at greatest risk.
Objective: To establish risk factors for developing glaucoma after pediatric cataract surgery [glaucoma following cataract surgery (GFCS)].
Methods: Single-center, retrospective, longitudinal study of patients who underwent lensectomy for pediatric cataracts from 2008 to 2020. Included eyes presented with congenital or acquired pediatric cataracts or an anterior form of persistent fetal vasculature, and a follow-up of at least 1 year. Exclusion criteria were the presence of preexisting intraocular pressure elevation, congenital glaucoma, syndromic cataracts, and a history of trauma or uveitis. Demographic and clinical data were collected. Our primary outcome was the development of GFCS. Multivariable logistic regression with generalized estimating equations was used to model the association between potential predictors and the risk of GFCS.
Results: A total of 110 eyes from 74 patients were included, 38 with unilateral and 36 with bilateral pediatric cataract surgery. The average surgery age was 24.71 ± 37.26 months, with 74 eyes (67.3%) undergoing surgery ≤12 weeks of age. Patients were followed for 9.96 ± 3.64 years after surgery. Twenty-eight eyes (25.45%) developed GFCS, all requiring glaucoma surgery. In multivariable analysis, surgery before 12 weeks of age [odds ratio (OR): 34.74; P < 0.001], presence of microcornea (OR: 12.90; P = 0.002), and presence of other AS abnormalities (OR: 52.71; P < 0.001) were significantly associated with the development of GFCS.
Conclusions: The development of GFCS is a common and relevant adverse event after pediatric cataract surgery whose management is challenging. Age at surgery, the presence of microcornea, and the presence of other AS abnormalities can be used to identify those at greatest risk.
