Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Tubular field with temporal island

End-stage glaucoma leaves a tunnel of central vision and a temporal island because the nasal field is lost early, leaving a central tunnel and a temporal island. Earlier signs are paracentral scotoma, Seidel scotoma and Bjerrum arcuate scotoma, with nasal step.
