Clinical Characteristics and Treatment Outcomes of Pediatric Glaucoma: A Retrospective Cohort Study

Objectives: This study aimed to evaluate clinical characteristics and treatment outcomes in a cohort of pediatric patients with glaucoma over 10-year period at a tertiary referral center. Methods: Medical records of patients younger than 18 years diagnosed with glaucoma between 1 January 2013 and 31 December 2023 were retrospectively reviewed. Diagnoses were classified according to the Childhood Glaucoma Research Network (CGRN). Demographic data, clinical characteristics and surgical outcomes were analyzed. Statistical analyses included Student's t-test, one-way ANOVA, and corresponding non-parametric methods (α = 0.05). Results: A total of 105 patients (168 eyes) were included, with a mean age of 5.52 ± 5.61 years, and a mean duration of follow-up of 5.41 ± 3.37 years. Mean baseline intraocular pressure (IOP) was 24.41 ± 10.85 mmHg. Secondary glaucoma was the predominant category (69%), led by glaucoma following cataract surgery (26%). Bilateral disease occurred in 60% of cases, more frequently in secondary forms. Surgery was performed in 57.4% of glaucomatous eyes. All subtypes except glaucoma following cataract surgery (GFCS) achieved significant reductions in IOP from baseline (p < 0.01). Despite effective IOP control, final visual acuity remained limited in many patients, especially those with glaucoma associated with non-acquired ocular anomalies or following cataract surgery. Worse baseline vision and higher presenting IOP were associated with poorer final acuity. Conclusions: Secondary glaucoma, particularly GFCS, was the most common form of pediatric glaucoma in this cohort. Although IOP control was generally successful, visual outcomes frequently remained suboptimal, highlighting the importance of early detection, comprehensive management, and close long-term monitoring.
