Prevalence of Glaucoma Following Paediatric Cataract Surgery in an Australian Tertiary Referral Centre

Purpose:Secondary glaucoma following childhood cataract surgery remains the most common complication in the paediatric population. This study aimed to determine the incidence, time to progression and risk factors associated with the development of secondary glaucoma following childhood cataract surgery in a paediatric population. Outcome measures were the detection of secondary glaucoma, postoperative time frame to development of glaucoma and risk factors in its development. Patients and Methods:A retrospective case series was conducted between 2003 and 2017 at a tertiary children's hospital in Sydney. The patient population included those 16 years or less of age who underwent congenital cataract extraction, with or without an intraocular lens implantation and who had been followed up for a minimum of six months following surgery. Patients were excluded if they had cataract aetiology other than congenital idiopathic cataract. Multivariate Cox Regression analysis was used to determine relevant risk factors. Results:A total of 320 eyes in 216 patients were included in the study. Secondary glaucoma developed in 11.9% of eyes. In those that developed secondary glaucoma, the average time to onset from surgery was 3.2 years (median 2.75 years). The mean age of diagnosis of secondary glaucoma was 4.58 years (median 3.5 years, range 2.5 months to 13.23 years). Microcornea was the only adverse characteristic significantly associated with an increased risk of secondary glaucoma (HR 6.30, p 0.003). Conclusion:Despite modern surgical techniques, glaucoma remains a significant long-term sequela in children following cataract surgery.

Automated summary

This study aimed to determine the incidence, time to progression, and risk factors associated with secondary glaucoma following childhood cataract surgery in the pediatric population. The results showed that the incidence of secondary glaucoma after cataract surgery was 11.9%, with an average time to onset of 3.2 years. Microcornea was the only adverse characteristic significantly associated with an increased risk of secondary glaucoma. Despite advances in surgical techniques, glaucoma remains a significant long-term complication following cataract surgery in children.
