Which optic nerve condition commonly has a relatively favorable visual prognosis?

• A. NAION
• B. AAION
• C. Diabetic papillopathy
• D. Papilledema

Answer: (C)

Visual prognosis depends on what’s causing the optic nerve swelling. Diabetic papillopathy is a mild, self-limited disc edema seen in diabetes that usually causes little permanent damage to the nerve fibers, so vision is typically preserved or returns to baseline as the edema resolves. In contrast, ischemic optic neuropathies involve actual damage from reduced blood flow, and both non-arteritic and especially arteritic forms tend to produce permanent vision loss more often. Papilledema, due to raised intracranial pressure, can have variable outcomes but is not characterized by consistently favorable visual prognosis—the outcome hinges on how quickly and effectively the underlying pressure is managed.
