- A. Latent convergent squint
- B. Alternate divergent squint
- C. Associated with accommodation reflex
- D. Latent divergent squint
Click “Show more” to see the answer and explanation.
Correct Answer: D. Latent divergent squint
Explanation:
Exophoria refers to a latent tendency for the eyes to diverge, kept in check by binocular fusion. It becomes apparent during dissociation, such as in cover-uncover tests.

- B. 1.33
- C. 1.37
- D. 1.42
Click “Show more” to see the answer and explanation.
Correct Answer: C. 1.37

- B. Ciliary ganglion
- C. Edinger-Westphal nucleus
- D. Optic tract
Click “Show more” to see the answer and explanation.
Correct Answer: B. Ciliary ganglion
