Congenital glaucoma and retinal dysplasia.
The differential diagnosis of leukocoria (pseudoglioma) in the neonate includes multiple conditions, including malformations with retinal dysplasia as a component. Typically bilateral, retinal dysplasia is characteristically seen in microphthalmic eyes. Certain chromosomal defects have been described. The case reported herein presented in the first month of life with an enlarged eye, elevated intraocular pressure, prominent iris vasculature, and leukocoria. Family history was positive in one respect: this is the second child of a Viet Nam veteran exposed to Agent Orange. The first child, from a different mother, also had birth defects. Other than his left eye, the child is completely normal. Ultrasonography showed posterior vitreous opacities of indeterminate configuration. CT scan suggested a posterior intraocular mass. Histologically, the principal features were an anomalous, largely unformed corneoscleral angle, intraocular hemorrhage, and retinal dysplasia. Light microscopic studies were performed. The corneoscleral angle revealed an anteriorly inserted iris with an absence of trabecular meshwork and Schlemm's canal. This case is considered unique on the basis of the association of retinal dysplasia with congenital glaucoma and larger-than-normal eye. The significance of reported paternal exposure to Agent Orange in this instance is unknown.[1]References
