Bilateral optic disc head drusen manifesting as unilateral episodic visual field obscuration: A case report

Abstract

Optic nerve head drusen (ONHD) are formed within the substance of the optic disc due to the accumulation of calcified hyaline-like material. They are generally misdiagnosed as papilledema since they elevate the disc and blur the disc margins. In this report, we describe a 22-year-old female patient with unilateral, episodic, partial visual field obscuration diagnosed as bilateral ONHD, the and pathogenesis, diagnosis and possible complications of disc drusen are discussed.
