Mofti A, Alharbi A, Alsuhaibani M, et al. - In the present study, the researchers sought to report the rates of success of Ahmed glaucoma valve (AGV) surgery in early childhood glaucoma and factors correlated with success. Children with primary congenital or early childhood secondary glaucoma who had AGV surgery over a 10-year period (one eye per child) at a single institution have been identified. In total, 178 patients [125 with primary congenital and 53 with secondary childhood glaucoma] were identified (median age, 5.8 ± 5.5 years). In children with primary congenital glaucoma, the AGV is associated with high short-term success, but the 10-year success rates are poor. A more refractory outcome could be associated with younger age and secondary childhood glaucoma.
