Question: Based on the OCT images, what visual field defect do you expect the patient present with?

Question: A right relative afferent pupillary defect was noted in the patient. Where does the lesion localize?

Question: Based on the retrochiasmal location of the lesion at the optic nerve tract, what type of deficit do you expect to see in OCT RNFL?

Learning Objectives:

1. Describing the presentation and localization of homonymous hemianopia visual field defects

2. Recognizing bow-tie atrophy defects on RNFL OCT.
