title: Tangent Streak RGP bifocal contact lenses in the treatment of accommodative esotropia with high AC/A ratio.
abstract: Patients with the diagnosis of high accommodative convergence/accommodation (AC/A) ratio, accommodative esotropia traditionally have been fit with bifocal spectacles. For cosmetic reasons, however, many patients prefer non-spectacle correction. Orthoptics, miotics, contact lenses, and surgery have been used as alternatives. We describe the treatment of three patients with the Tangent Streak bifocal rigid gas permeable (RGP) contact lens in which functional control of the patient's deviation was attained. Tangent Streak RGP bifocal contact lenses offer an acceptable alternative to bifocal spectacles, surgery, miotics, or orthoptics in the treatment of accommodative esotropia with high AC/A ratio.
