To compare the demographic and clinical distribution of primary and secondary congenital glaucoma from a registry at King Khaled Eye Specialist Hospital. Registry-based cohort study. Review of registry data that included new patients with congenital glaucoma seen between 2001 and 2003 (29 months); analysis of the demographic data and clinical features of primary and secondary congenital glaucoma at presentation. A total of 325 eyes of 180 patients were included. Most patients had primary congenital glaucoma (80%). The mean (± SD) age at presentation for primary congenital glaucoma was 3.8 ± 10.7 months and for secondary congenital glaucoma was 4.3 ± 7.9 months. Most primary congenital glaucoma and secondary congenital glaucoma patients had bilateral disease (82.6%; 74.3%). Primary congenital glaucoma was equally distributed by sex but secondary congenital glaucoma was 1.5-fold more common in male patients. A positive family history was elicited in 30%, and almost 60% had a history of consanguinity in both groups. The mean intraocular pressure and corneal diameter were comparable in both groups but the axial length was significantly longer in primary congenital glaucoma and cup-to-disc (C/D) ratio greater in secondary congenital glaucoma. In the primary congenital glaucoma group, corneal haze showed a significant relationship with most clinical parameters. In primary congenital glaucoma, a positive correlation was noted between age at presentation and increasing corneal diameter and axial length but a negative relationship was noted with C/D ratio and corneal haze, whereas for secondary congenital glaucoma only axial length was positively correlated. The congenital glaucoma registry provides unique baseline data on primary congenital glaucoma and secondary congenital glaucoma in Saudi Arabia that will enable us to better understand the disease in the Kingdom and region.
