Multiple Choice

In glaucoma, which of the following visual fields is typically affected first?

In glaucoma, the damage to retinal ganglion cells and their axons tends to affect the outer parts of the visual field first. The nerve fiber bundles that serve the peripheral retina—the arcuate pathways around the optic nerve head—lose function early, producing scotomas at the margins of vision and often a ring of peripheral field loss while central (foveal) vision is still intact. Central vision remains preserved until later stages, and color or night vision aren’t typically the first domains affected by glaucoma.
