Advanced Binocular Vision (ABV) Exam 2 Practice

Which statement best describes the TV trainer in anti-suppression therapy?

It is an active, physically demanding therapy. It relies on rapid eye movements to train fusion. It is typically contraindicated in all near tasks. It is a passive form of anti-suppression therapy.

Correct Answer:

It is a passive form of anti-suppression therapy.

Explanation:

The TV trainer is a passive form of anti-suppression therapy. It works by presenting binocular stimuli on a screen through filters so that both eyes participate in the viewing, encouraging the brain to fuse the images while the patient simply fixates and attends. There’s no requirement for active, physically demanding tasks or rapid, purposeful eye movements; the therapy relies on sensory input and binocular fusion, not on motor training. The idea is to reduce suppression by making fusion the natural outcome of viewing, rather than teaching the eyes to perform specific rapid or strenuous actions.
