History

Parents bring their child to their physician, reporting that the child's eyes appear to be turned out.

Next:

Physical

Patients appear to have a large angle kappa or nasally deviated corneal light reflex. By performing the cover-uncover test, no movement can be demonstrated. In the case of a dragged macula, an ophthalmoscope examination reveals an ectopic macula displaced temporally.

Causes

A common cause of pseudoexotropia is a dragged or temporally displaced macula associated with retinopathy of prematurity.

Retinal scarring in the temporal periphery caused by Toxocara canis is another cause of a temporally displaced macula resulting in pseudoexotropia.
