AOA Vision Therapy and Rehabilitation

Question 1

The primary goal of vision therapy for convergence insufficiency is to:

Accepted Answer

Improve convergence amplitude and fusional vergence ranges

Answer

Vision therapy for CI aims to recondition the neuromuscular control of convergence, increasing both the amplitude and the positive fusional vergence reserves.

Question 2

Amblyopia is defined as reduced best-corrected visual acuity in one or both eyes due to:

Accepted Answer

Abnormal visual experience during the critical period of development

Answer

Amblyopia is a neurodevelopmental condition caused by abnormal visual input (deprivation, strabismus, or anisometropia) during the sensitive period, leading to cortical suppression.

Question 3

Which treatment is considered the gold standard for anisometropic amblyopia?

Accepted Answer

Full refractive correction followed by patching or atropine penalization of the fellow eye

Answer

Full refractive correction must be provided first; many children with anisometropic amblyopia improve with glasses alone, and patching or atropine is added if improvement plateaus.

Question 4

The AC/A ratio describes the relationship between:

Accepted Answer

Accommodative convergence and accommodation

Answer

The AC/A ratio quantifies how many prism diopters of convergence (AC) are elicited per diopter of accommodation (A) stimulated.

Question 5

Strabismus surgery for constant exotropia primarily aims to:

Accepted Answer

Realign the visual axes to restore binocular vision potential

Answer

Strabismus surgery repositions the extraocular muscles to realign the eyes, creating the opportunity for binocular fusion and stereopsis to develop or be restored.
