Unsuccessful surgical excision of optic nerve drusen

Abstract

To report the case of failed surgical excision of optic nerve drusen (OND).Case report. A 53-year-old woman presented with bilateral OND leading to progressive field defects and LE light perception and RE 20/25 vision. A vitrectomy was performed on the legally-blind left eye to test the resectability of OND.The removal of superficial OND failed because the singular-appearing superficial OND presented as one large mass with multiple excrescences on its surface. Retinal vessels passed through it, which made an excision impossible.OND cannot always be removed surgically, due to their variable consistency and hardness.
