Optic disc shape in patients with long-lasting unilateral esotropia and exotropia.

ABSTRACT:

Background

Horizontal eye movements have been proposed to induce biomechanical stress and strain on optic nerve head. Since strabismus may lead to sustained adduction or abduction, we investigate the effects of long lasting unilateral horizontal strabismus on the morphology of optic disc.

Methods

The observational cross-sectional study included patients with unilateral constant horizontal strabismus lasting for more than two years. The patients underwent an ophthalmological examination including refraction and morphometry of the optic nerve head. A prism cover test using right angle glass prism was performed to measure the magnitude of the ocular deviation.

Results

The study included 70 patients with a unilateral constant strabismus (35 esotropic patients, 35 exotropi
