In strabismus assessment, which finding would support diagnosis aside from misalignment?

• A. Impaired extraocular muscles
• B. Normal binocular vision
• C. Normal color vision
• D. Everted eyelid

Answer: (A)

Strabismus isn’t just about eyes not pointing together; assessing it also looks at how the extraocular muscles and their nerves are functioning. If the extraocular muscles are impaired, you’ll see limitations or weakness in specific eye movements, which helps explain why the eyes are misaligned and supports the diagnosis as a neuromuscular or mechanical issue causing the deviation. Normal binocular vision would usually not be expected with strabismus, since coordinated depth perception relies on aligned eyes. Normal color vision or an everted eyelid aren’t related to eye alignment and don’t point to the strabismus diagnosis.
