BILATERAL ENOPHTHALMOS ASSOCIATED WITH HYDROCEPHALUS AND VENTRICULOPERITONEAL SHUNTING

Background: Progressive bilateral enophthalmos in the absence of previ ous trauma is rare. Methods: Three patients with progressive bilateral severe enophthalmos whose only significant medical history was that o f congenital hydrocephalus were treated by ventriculoperitoneal shunt placement. Results: The patients demonstrated severe bilateral enophth almos with poor eyelid apposition to the globes, resulting in superfic ial keratopathy. Orbital computed tomographic scans confirmed the seve re enophthalmos, with apparent reduced orbital fat volume. Orbital bon y anatomy appeared normal. Conclusions: Bilateral progressive enophtha lmos may be associated with hydrocephalus and ventriculoperitoneal shu nting. The causal mechanism remains speculative.
