BACKGROUND: This study aimed to identify the incidence of and risk factors for postoperative glaucoma-related adverse events at various time points after congenital cataract surgery. METHODS: This retrospective cohort study enrolled 259 eyes from 174 patients (surgical age ≤ 7 years) who underwent congenital cataract surgery. All surgical procedures were conducted at the Eye Hospital of Wenzhou Medical University between May 2011 and March 2019. Patients were classified into group 1 [primary intraocular lens (IOL) implantation, N = 111 eyes], group 2 (secondary IOL implantation, N = 85 eyes), and group 3 (no IOL implantation, N = 63 eyes). We recorded demographic factors and incidence and risk factors for glaucoma-related adverse events. RESULTS: Glaucoma-related adverse events occurred in 21 (8.1%) eyes, whereas 27 (10.4%) eyes developed steroid-induced ocular hypertension. The percentage of glaucoma-related adverse events was 0%, 1.2%, 1.2%, 1.6%, 4.0%, and 8.9% at 1 month, 6 months, 1 year, 2 years, 3 years and 4 years after surgery, respectively. Sixteen (18.8%), five (7.9%), and zero eyes developed glaucoma-related adverse events in groups 2, 3, and 1, respectively. Family history of congenital cataract [hazard ratio (HR), 50.463; 95% confidence interval (CI), 7.051-361.139; P < 0.001], preoperative central corneal thickness (CCT) [HR, 1.021; 95% CI, 1.009-1.034; P = 0.001], preoperative horizontal corneal diameter (HCD) [HR, 3.922; 95% CI, 1.558-9.804; P = 0.004], and preoperative lens thickness (LT) [HR, 3.745; 95% CI, 1.344-10.417; P = 0.012] were identified as predictors of postoperative glaucoma-related adverse events. CONCLUSIONS: Family history of congenital cataract, thicker preoperative CCT, smaller preoperative HCD, and thinner preoperative LT are the main risk factors of postoperative glaucoma-related adverse events. Regular monitoring of children after cataract surgery with these risk factors may help ophthalmologists detect susceptible individuals and provide timely interventions in the clinic.
