Vascular Third Nerve Compression—A Possible Cause of Episodic Vertical Diplopia?

Abstract

We report a 74-year-old man with a 2-year history of episodes of vertical diplopia. In the beginning, there was one episode every 2–3 months, which increased over time to an average of one episode every 2 weeks. These complaints were attributed to an MRI-documented vascular third nerve compression. Treatment with gabapentin (400 mg q.i.d.) was followed by cessation of episodic diplopia.
