Precis: In this study, huge time delay was observed between first primary congenital glaucoma (PCG) symptom recognition by parents to ophthalmological diagnosis and this delay was unchanged over time. Bilateral affliction and mean presenting intraocular pressure (IOP) remained unaltered. Purpose: To compare the trends in presentation of patients with PCG over 3 different time periods at 10-year intervals (1998, 2008, and 2018) managed by a single surgeon at one of the largest tertiary eye care centers in South India. Methods: Retrospective analysis of 313 eyes of 172 patients diagnosed to have PCG and treated at the L V Prasad Eye Institute (LVPEI) between January and December of the 3 specified years. Data collected included age at symptom recognition and at presentation, sex, affected eye, signs and symptoms, time between onset of symptoms and diagnosis (diagnostic delay), corneal clarity, and IOP. Results: Of the 172 patients, 48 (27.9%), 76 (44.2%), and 48 (27.9%) belonged to 1998, 2008, and 2018, respectively. Bilateral affliction (79% to 84%) was common and there was no sex predilection. The median age at recognition of first symptoms by caregivers/parents was 1 day (interquartile range, 1 to 30), and at diagnosis was 120 days (interquartile range, 30 to 378). Overall, presentation to LVPEI was delayed by >3 months in 80 (46.5%) children, and there was no statistically significant difference in the duration of delay over time (P=0.13). There was no significant difference in the mean presenting IOP over time (P>0.05). Conclusions: We provide unique single center-based information of trends in the presentation of patients with PCG over 3 decades. Diagnostic delay was common, and a large number of characteristics of patients with PCG in South India have remained unchanged, particularly, age at onset and at diagnosis and laterality.
