Visual Fields were performed and shown below.

Question: What is the likely diagnosis in this patient?

Learning Objectives:
1. Interpreting OCT RNFL and macular cube images in patients with pre-perimetric glaucoma.
2. Identifying RNFL deficits corresponding to the inferior and superior vulnerability zones.
3. Identifying reduced retinal thickness corresponding to the macular vulnerability zone.
4. Correlating OCT deficits with visual field changes.
