Monovision for treatment of accommodative esotropia with a high AC/A ratio.
OBJECTIVE
The purpose of this study was to determine whether monovision will successfully reduce the near esodeviation in patients with high AC/A ratio accommodative esotropia.


METHODS
The records of all patients who wore monovision contact lenses for at least 3 months were retrospectively reviewed to determine baseline patient characteristics, long-term motor alignment, sensory status, and patient convenience.


RESULTS
TEN patients 10 to 28 years of age wore monovision contact lenses for a mean of 28.7 months to date. All patients maintained an esodeviation of < or = 10 prism diopters at distance and near, except 1 patient whose near esodeviation increased over time. Of the 5 patients for whom data were available, 1 experienced a significant decrease in stereoacuity. No patients discontinued monovision because of visual symptoms; however, 1 did so because of the inconvenience of contact lens care. No serious ocular side effects from contact lens wear were noted in the study.


CONCLUSIONS
Use of monovision contact lenses is a safe and effective method of reducing near-angle esodeviation associated with nonrefractive high AC/A ratio accommodative esotropia. Many patients are willing to accept the visual compromises inherent in monovision to eliminate wearing bifocal spectacles.
