A normal finding during funduscopic examination rules out serious defects of which structures?

• A. The cornea, aqueous chamber, lens, and vitreous chamber
• B. The retina and optic nerve
• C. The iris and pupil
• D. The sclera and choroid

Answer: (A)

Funduscopic examination lets you visualize the back part of the eye—the retina, the optic nerve head, the macula, and the retinal vessels. A normal fundus means these posterior structures appear without serious abnormalities, so it effectively rules out major pathologies of the retina and the optic nerve (such as retinal detachment, hemorrhage, or optic neuropathy). The cornea, anterior chamber, lens, and vitreous chamber are not the primary targets of this exam, so issues in those structures would not be ruled out by a normal fundus alone.
