Comparative Analysis on Accommodative Response Based on Degree of Anisopia

Purpose : This study aimed to compare each accommodative response based on degree of anisopia. Methods : This study was performed with 10 adult males and females(21.60±0.50 years old) under the criteria; 1) no subject had ophthalmic surgery or disease, 2) all subjects were within normal vision range and had no need to correct, and 3) all subjects had same visual functions. The contact lenses with +1.00, +1.50, and +2.00 D were monocularly worn on non-dominant eye one after the other. The accommodative responses were measured by a binocular open-field autorefractometer under the accommodative stimulus of 100, 40, and 20 cm that enabled dynamic measurement. Results : As a viewing distance became shorter the accommodative response increased in both dominant and non-dominant eyes. For non-dominant eyes the accommodative response has decreased as the degree of myopia has become greater in comparison with the naked eyes, while for dominant eyes the accommodative response increased(p
