: PRéCIS: The overall incidence of postoperative suspected glaucoma and glaucoma after congenital cataract surgery is low; however, the identification of the associated risk factors helps to monitor susceptible individuals and to provide real-time surveillance and timely intervention. PURPOSE: Pediatric patients who have undergone surgery for congenital or infantile cataracts have a risk of developing suspected glaucoma and glaucoma, but the current evidence does not address our understanding of the incidence and associated risk factors of suspected glaucoma/glaucoma for application in clinical standard care. Therefore, this study investigated the incidence of and risk factors for suspected glaucoma/glaucoma in patients who have undergone surgery for congenital/infantile cataracts. METHODS: This study used a prospective cohort of 241 eyes from 241 patients who were 10 years of age or younger and who had undergone congenital/infantile cataract surgeries and were recruited from January 2011 to December 2016 at the Zhongshan Ophthalmic Center. Pediatric patients who underwent cataract surgery were classified into 2 groups according to intraocular lens (IOL) implantation. The patients' baseline characteristics and the incidence and risk factors for suspected glaucoma/glaucoma were assessed. RESULTS: The incidence of suspected glaucoma after cataract surgery was 10.70% [26 of 241 eyes; 95% confidence interval (CI), 6.88%-14.70%]. The rate of suspected glaucoma developing into glaucoma was 26.92% (7 of 26 eyes; 95% CI, 9.87%-43.97%), and the incidence of glaucoma was 2.90% (7 of 241 eyes; 95% CI, 0.79%-5.03%). Our study revealed that the incidence of suspected glaucoma/glaucoma in patients who did not receive IOL implantation was 13.91% (21 of 151 eyes; 95% CI, 8.39%-19.42%), and the incidence in patients who received IOL implantation was 5.56% (5 of 90 eyes; 95% CI, 8.23%-10.28%). The preoperative central corneal thickness (hazard ratio, 1.003; 95% CI, 1.001 to 1.004; P=0.004) and a family history of congenital cataracts (hazard ratio, 2.314; 95% CI, 1.004-5.331; P=0.049) were significant risk factors in patients without IOL implantation. Patient age at the time of cataract surgery was not a statistically significant risk factor for the development of suspected glaucoma/glaucoma in patients without IOL implantation. CONCLUSIONS: Identification of the incidence of and risk factors for suspected glaucoma/glaucoma may help clinicians monitor susceptible individuals and provide timely surveillance and interventions in a clinical setting. Age at the time of cataract surgery was not a risk factor for suspected glaucoma/glaucoma in patients without IOL implantation, and this may allow the timing window for pediatric cataract surgery to be expanded and support new insights into the optimal timing of surgery for standard care.
