DIFFICULTIES IN TREATING ANISOMETROPIA AND THE SOLUTIONS

دانشجوی کارشناسی ارشد اپتومتری دانشگاه علوم پزشکی شهید بهشتی

Abstract: Binocular vision can be disturbed by large differences in the refractive error between the two eyes: anisometropia. When this is left uncorrected, central suppression areas can develop in the eye with the more blurred vision. Anisometropia over 1.50D results in a significant increase in the risk of amblyopia and decrease of binocular function and higher anisometropia is likely to be associated with worse amblyopia and stereoacuity. Poorer stereoacuity is associated with reduced performance at motor tasks and at driving . If anisometropia occurs in young patients, and particularly before the age of 6 years when the visual system is still not firmly established, amblyopia may also be present. with patients of any age, the prescribing of glasses to correct anisometropia may present two other problems: prismatic effect and anseikonia in both cases, these difficulties will cause more problems in older patients, with previously uncorrected patients or where a large change in prescription is given.
