What is a Heterophoria?

Heterophoria or latent squint is defined as a condition in which eyes in the primary position or in their movement are maintained on the fixation point under stress only, with the aid of corrective fusion reflexes. When the influence of fusion is removed, the visual axis of one eye deviates.

Is strabismus linked to autism?

Research in the Journal Strabismus found that the prevalence of strabismus is higher in people with autism spectrum disorder than in the general population. Visual defensiveness: People with autism often have a hypersensitive reaction to stimuli.
