Optic tract injury after anterior temporal lobectomy

Ophthalmology. 1989 Jul;96(7):1065-70. doi: 10.1016/s0161-6420(89)32783-7.


Three patients had complete homonymous hemianopia with clinical and neuroimaging characteristics of ipsilateral optic tract infarction after anterior temporal lobectomy for seizure control. This injury presumably resulted from irritative vasospasm of the anterior choroidal artery. The features of this pure optic tract syndrome should be distinguished from the more common compressive optic tract syndrome which generally also impairs ipsilateral optic nerve function.
