A case of developmental glaucoma presenting with abdominal colic and subnormal intraocular pressure

A healthy baby boy presented with abdominal colic. He was subsequently noted to have enlarged, edematous corneas. A clinical diagnosis of developmental glaucoma was made despite ocular hypotony. Trabeculectomies were designed to include peripheral cornea. This served as a biopsy to confirm the diagnosis and as a surgical treatment for the condition. Morphological examination of the outflow system revealed findings compatible with a diagnosis of developmental glaucoma: a hypoplastic trabecular meshwork which contained an abundance of abnormal collagenous tissue in the extracellular spaces and the presence of endothelial cells overlying a continuous collagenous membrane. In the iris stroma there were numerous abnormal blood vessels, with a paucity of mural contractile cells.
