Гиперметропический астигматизм — отклонение, характеризующееся ухудшением и изменением зрительной функции человеческого организма.

Характеристика. У человека с нормальным зрением глазное яблоко отвечает за изменение света, попадающего на его поверхность. При гиперметропическом астигматизме свет преломляется по-другому, за счет чего общий вид изображения искажается, принимает неправильные черты. Преимущественно люди, имеющие подобный дефект зрения, страдают еще таким, чаще возрастным изменением, как дальнозоркостью. Так как свет не может сфокусироваться на сетчатке, а передвигается ближе к переднему краю, то предметы, расположенные вблизи кажутся как в тумане, размытыми и совершенно нечеткими. Гиперметропический астигматизм нельзя вылечить, так как это физическое отклонение глазного яблока, но исправить, скорректировать, чтобы обеспечить человеку комфортное существование, можно.

Гиперметропический астигматизм отличается от роговичного и хрустальникового астигматизма именно фокусом световых лучей. В других случаях наблюдается только отклонение глазного яблока от нормы. А в случае гиперметропии помимо неправильной формы глаза изменяется и направление световых лучей.

Врачи в первую очередь исследуют яблоко глаза человека. С помощью специальных аппаратов определяется условная степень развития такого заболевания, как астигматизм зрения. Он делится на простой и сложный. Первый тип характеризуется внешним воздействием — человек получил «заболевание» после травмы, аварии, сильного перенапряжения и других факторов. Такой тип можно не только скорректировать, но и исправить полностью. Второй тип — врожденный. Его можно только немного исправить, избавить пациента от данного отклонения на совсем никак не удастся. Поэтому врачи советуют родителям, с первых дней жизни ребенка, наблюдать за ним с особой тщательностью. При первых признаках отклонения стоит показаться лечащему терапевту. Такие действия позволят сократить риски дальнейшего развития патологии.

Врачи часто сталкиваются с подобными проблемами. В первую очередь они осуществляют корректировку зрения с помощью аппаратов. Также советуют лечебную гимнастику для глазных мышц и мышц век. Все это способствует изменению внутриглазного давления, как следствие — общему изменению положения мышц глаза. Следовательно, световые лучи смогут пройти в нужном направлении.
