Which optic nerve head change is listed as a sign of fundic disease?

• A. Atrophies, cupped, swollen, hyperemic
• B. Pale pink optic nerve head with variable myelin
• C. Tapetum color may vary
• D. Pigment of choroid is common

Answer: (A)

Understanding changes at the optic nerve head helps identify fundus disease. The optic disc can show several telltale signs of pathology: to begin with, atrophy reflects loss of nerve fibers and results in pallor; cupping is the excavation of the nerve rim seen in conditions like glaucoma; swelling indicates edema from inflammation or increased pressure; and hyperemia describes increased redness from congestion. When you see a combination of atrophy, cupping, swelling, and hyperemia, it aligns with the typical spectrum of optic nerve head changes that signal fundic disease. Other descriptions describe variations or features not used as signs of optic neuropathy in routine exams—for example, a pale pink disc with variable myelin is not a standard disease sign, tapetum color is an animal-specific feature, and choroidal pigment variation is a normal trait rather than a sign of optic nerve disease.
