Which visual field finding may be observed in optic nerve head drusen?

• A. Generalized depression
• B. Superior arcuate defect
• C. Central scotoma
• D. Paracentral scotoma

Answer: (A)

Optic nerve head drusen can cause a diffuse, chronic optic neuropathy that lowers sensitivity across the entire visual field. On testing, this often appears as a generalized depression, meaning the entire field shows a uniform reduction in sensitivity rather than a localized defect. While focal patterns like arcuate, central, or paracentral scotomas can occur with other optic neuropathies or glaucoma, the most typical and distinguishing finding with drusen is this diffuse, generalized loss.
