Intermittent exotropia with high AC/A ratio: is it a bane to surgical cure? Some facts and fictions of the two clinical tests: occlusion of one eye and the use of +3.00 spherical lenses.

Abstract

Patients with intermittent exotropia and significantly more exodeviation at distance than at near, and classified to have high AC/A ratio by occlusion of one eye and the use of +3.00 spheres at near, do not necessarily have a high accommodation-convergence relationship but rather, other factors mimicking this high AC/A relationship. They do not necessarily develop a postoperative overcorrected high AC/A ratio esotropia.
