Functional burden of strabismus: decreased binocular summation and binocular inhibition.

ABSTRACT:

Importance

Binocular summation (BiS) is defined as the superiority of visual function for binocular over monocular viewing. Binocular summation decreases with age and large interocular differences in visual acuity. To our knowledge, BiS has not heretofore been well studied as a functional measure of binocularity in strabismus.

Objective

To evaluate the effect of strabismus on BiS using a battery of psychophysical tasks that are clinically relevant and easy to use and to determine whether strabismus is associated with binocular inhibition in extreme cases.

Design

Case-control study.

Setting

University-based eye institute.

Participants

Strabismic patients recruited during 2010 to 2012 from a preoperative clinic and control participants with no history of e
