Abstract:
We investigated the effect of experimentally induced anisometropia on binocular function. Unilateral myopia, hyperopia, or astigmatism(Axis 90degrees) was induced in eighteen adults with normal binocular function using softcontact lenses. Sensory status was assessed by measuring stereoacuity, Worth four dot test, and Bagolini lens test. Binocular function of all subjects decreased with increasing levels of anisometropia. In Worth four dot test, foveal suppression increased in proportion to the levels of anisometropia. Stereoacuity was similarly degraded by the induced anisometropia. Bagolinilens responses were normal in almost all subjects. Our study suggest that experimentally induced anisometropia cause significant abnormalities in binocular function in adults.
