To determine the risk factors and incidence of glaucoma following congenital cataract surgery in our case series.

Patients and Methods:

Records of children who underwent cataract surgery between January 2001 and December 2009 were reviewed retrospectively. Age at primary surgery, microcornea, aphakia/ pseudophakia and associated systemic pathology were analyzed as potential risk factors for glaucoma secondary to surgery. Sixty-five eyes of 37 patients having a minimum 6-month follow-up were included in the study.


Age at surgery was 35.6±43.9 months (2 months-17 years) with a follow-up period of 38.6±28.1 months (6 months-8.5 years). Glaucoma developed in 8 patients (14 eyes; 21.5%). Time between surgery and glaucoma diagnosis was 47.3±23.3 months (20 months-7 years). Glaucoma incidence in aphakic and pseudophakic cases did not differ. Glaucoma development significantly correlated with age at surgery (p<0.001), microcornea (p=0.001) and presence of systemic pathology (p=0.007). Mean age at surgery was significantly lower in patients with glaucoma diagnosis (7.4 months) than in those who did not develop glaucoma (43.4 months). However, the mean follow-up period was significantly longer in patients with glaucoma (p=0.003). Whereas glaucoma developed in 60% and 38.5% of the eyes of patients with microcornea and systemic pathology, respectively, this dropped to 14.5% and 10.3% in cases with normal corneal diameter and absence of systemic pathology, respectively.


Early age at cataract surgery, microcornea and systemic pathologies are important risk factors for development of secondary glaucoma and the incidence of glaucoma increases with longer follow-up. To prevent visual loss, patients should be followed up lifelong.(Turk J Ophthalmol 2011; 41: 358-63)
