Fixational Eye Movements in Strabismus and Amblyopia: Implications for visual function deficits and treatment outcomes

We have developed robust and objective measures that do not depend upon the young patient’s cooperation or provider’s assessments of visual acuity and strabismus angle and quantifies the entire spectrum of visual function deficits in a fast, reliable, and pediatric-friendly way. The systematic analysis of fixation eye movement traces obtained in the lab in patients with binocular vision disorders has revealed several features that can be utilized to detect the presence and severity of amblyopia and angle and control of strabismus. We have found that fixation eye movement abnormalities correlate with reduced light sensitivities and depth perception and extent of suppression of vision experienced by these patients. We have also found that assessment of fixation eye movement characteristics can be a useful tool to predict functional improvement post amblyopia and strabismus repair. https://fescenter.org/team/investigators/ghasia-fatema-md/
