Eye Movements and Accommodation Patterns in Strabismus

In his clinical work as a pediatric ophthalmologist, Dr. Chandna has noted seemingly different patterns of eye movements as patients recover binocular fusion during a routine cover test. Strabismus, a common conditin is often suspceted to be a mismatch beywen eye movemnets and focusing power (accommodation) of the eyes. Given that outcomes forand treatment  of strabismus are often less than ideal , we are asking the extent to which these recovery eye movements ad relationshoip with accommodation are indiciative of how the binocular system is failing - and thus these patterns can be predictors as to which patients are most likely to benefit from medical or surgical intervention. In this project, we are first developing methods for eye tracking ad measi=urihng accommdtion simultaneously in pediatric patients in a clinical setting. The next step is to gather large amounts of accommodation and recovery eye movement data and follow the course of treatment and outcome for patients. Classification of these data will reveal whether or not discernable patterns are reliable, and the degree to which they predict  outcome.

    We use rigorous scientific research with the goal to improve detection and treatment outcomes for individuals with strabismus, amblyopia, and cerebral visual impairment.
