Hemoglobin Spherulosis in the Vitreous Cavity

Abstract

A 50-year-old woman was evaluated for a subretinal hemorrhage that extended into the vitreous of the right eye. Examination showed multiple refractile brown spherules in the vitreous. A vitrectomy was performed, and pathologic examination of the spherules showed them to be composed of free hemoglobin. Free-hemoglobin spherulosis in the vitreous, like cholesterosis bulbi, is a manifestation of vitreous hemorrhage.
