[Trabeculotomy before the estimated delivery date. Case report of a preterm infant with buphthalamus].

Congenital glaucoma is a disease potentially leading to blindness in children. It poses a diagnostic and therapeutic challenge even though new knowledge has been acquired and a sufficient understanding of the pathogenesis has been gained. New discoveries, such as the exact time when Schlemm's canal develops could lead to a prenatal diagnosis and therefore surgical intervention so that other complications including blindness can be avoided. This case report demonstrates that an early prenatal eye screening with ultrasound (after approximately 30 weeks of pregnancy) would be desirable in order to diagnose buphthalmus early and to plan postnatal surgery.
