Eye dominance and the mechanisms of eye contact.

Purpose: To determine the effect of eye dominance on the nature of perceived eye contact and perceived eye misalignment.

Methods: In this experimental study, strabismic and nonstrabismic human subjects over the age of 18 were assessed for strength of eye dominance, being classified as either weakly or strongly dominant. They were asked whether they perceived residual misalignment following strabismus surgery (if applicable).

Design of and normative data for a new computer based test of ocular torsion.

Purpose: To evaluate a new clinically practical and dynamic test for quantifying torsional binocular eye alignment changes which may occur in the change from monocular to binocular viewing conditions.

Methods: The test was developed using a computer with Lotus Freelance Software, binoculars with prisms and colored filters. The subject looks through binoculars at the computer screen two meters away.
