Objective measurement of eye alignment using eye tracking

Jul 31, 2018Research, Technology & Vision

Strabismus (“squint” or an “eye turn”) is a condition where the two eyes are not aligned. It affects about 1 in 20 children. Some patients with strabismus need surgery to align their eyes. Surgical success depends on having good measurements of strabismus angle, eye movement control, and binocular vision (how well the brain can combine information from the eyes). Current clinical measures are not always reliable for predicting surgical outcomes.

This study aims to develop and pilot test an objective, automated eye-tracking method to measure strabismus angle and assess binocular vision in children and adults. We will test people with and without strabismus, and also examine how eye alignment and binocular vision may change after eye muscle surgery.
