Strabismus is characterized by which description when both eyes are open?

• A. One eye deviates inward or outward when both eyes open
• B. Double vision with head tilt
• C. Color vision deficiency
• D. Hearing loss

Answer: (A)

Strabismus is a misalignment of the eyes. When both eyes are open, one eye turns inward toward the nose (esotropia) or outward away from the nose (exotropia), so the eyes don’t point at the same object. This misalignment is what defines the condition. The brain may suppress the image from the misaligned eye to avoid double vision, which in children can lead to amblyopia if not addressed. The other options describe symptoms not characteristic of strabismus—diplopia with head tilt relates to binocular diplopia patterns, color vision deficiency is unrelated, and hearing loss is not connected to eye alignment.
