Optic Disc Drusen Presenting with Binasal Hemianopia

Abstract

Optic disc drusen (ODD) are defined as a form of calcific degeneration of the optic nerve. Visual field defects are seen in nearly 90% of the cases. We report a 32-year-old woman who was referred to our clinic with the complaint of longstanding blurred vision and nasal visual field defect in her both eyes. The diagnosis of ODD was made on the basis of clinical appearance of the optic nerves and confirmed by ancillary tests. Binasal visual field defect was observed in the automated visual field test. In conclusion, ophthalmologists should consider ODD in the differential diagnosis of advanced visual field loss and binasal hemianopia. (Turk J Ophthalmol 2013; 43: 371-3)
