Abstract

This study was conducted to investigate the influences of factors on binocularity in accommodative esotropia. On the basis of sensory tests, patients were divided into two groups, bifixation and monofixation. Bifixation, defined as stereopsis of 50 seconds or better, was present in 57 patients (62%). Monofixation (peripheral fusion) was present in the remaining 35 patients (38%). The first hyperopic glasses were significantly more likely to be prescribed to patients with bifixation than to those with monofixation while the esotropia is still intermittent(p<0.05). There were no significant differences between the bifixation and monofixation groups for age of onset of strabismus, amount of hyperopia, presence of amblyopia and anisometropia, time intervals between onset of strabismus and prescription of hyperopic glasses. In summary, maintenance of bifixation is possible in accommodative esotropia by effective therapeutic intervention during the intermittent phase.
