Fixation instability in anisometropic children with reduced stereopsis.

Fixation instability in anisometropic children with reduced stereopsis
 
Hyperopic anisometropia in children can be associated with abnormal stereoacuity and "microstrabismus," ....A total of 94 children with hyperopic anisometropia ... were evaluated ...with the use of the Nidek MP-1 microperimeter. .... the Randot Preschool Stereoacuity Test... was administered.....Stereoacuity was correlated with fixation instability ...visual acuity was more weakly correlated ...children with subnormal stereoacuity had fixation instability, and those with nil stereoacuity had the most instability. ..... data support the hypothesis that the binocular decorrelation caused by anisometropia can disrupt ocular motor development, resulting ..."flicks" that may mimic microstrabismus....
