CO Diagnosis & Management of Strabismus and Amblyopia 2

Question 1

A 4-year-old has 20/200 vision in the left eye with no structural abnormality. Best initial treatment after refractive correction is:

Accepted Answer

Patching the fellow (sound) eye

Answer

Occlusion therapy for amblyopia involves patching the sound (fellow) eye to force use of the amblyopic eye.

Question 2

Which of the following best describes anisometropic amblyopia?

Accepted Answer

Amblyopia resulting from unequal refractive error between the two eyes

Answer

Anisometropic amblyopia results from a significant difference in refractive error between the two eyes, causing chronic blur in one eye.

Question 3

The Krimsky test is used to measure:

Accepted Answer

Angle of deviation using prisms and the corneal light reflex

Answer

The Krimsky test measures the angle of strabismus by centering the corneal light reflex with a prism placed over the deviating eye.

Question 4

A child with esotropia shows a larger deviation on alternate prism cover test than on simultaneous prism cover test. This finding is most consistent with:

Accepted Answer

Monofixation syndrome

Answer

In monofixation syndrome, the APCT reveals a larger deviation because it breaks down any peripheral fusion, unmasking the full angle.

Question 5

In intermittent exotropia, the deviation is typically best controlled:

Accepted Answer

At near fixation

Answer

Near fusion is usually stronger than distance fusion in intermittent exotropia, so the deviation is better controlled at near.
