Retinal correspondence in typical accommodative esotropia.

Typical (refractive) accommodative esotropia is a form of acquired esotropia caused primarily by hypermetropia; correction of the hypermetropic refractive error with convex lenses generally leads to rehabilitation. A significant number of cases clinically diagnosed as typical accommodative esotropia do not, however, respond satisfactorily to this form of treatment, suggesting the presence of nonrefractive etiological factors. Fifty cases diagnosed by conventional methods as typical accommodative esotropia were examined with the fundus haploscope; abnormal or subnormal retinal correspondence was discovered in nearly 50% of the total. Congenital elements are thought to play a contributory role in these cases.
