Sickle cell hyphema with secondary glaucoma in a non-black patient.

A 5-year-old Mexican-American boy developed marked elevation of intraocular pressure in association with a small traumatic hyphema. Laboratory studies prompted by this clinical presentation revealed that the child had sickle trait. Pressure returned to normal after surgical evacuation of blood from the anterior chamber. Sickle cell hemoglobinopathy should be considered in the differential diagnosis of secondary glaucoma following blunt ocular trauma even in non-black patients.
