儿童弱视与屈光不正

REFRACTIVE ERROR AND AMBLYOPIA IN CHILDREN

本文名分析了3099例2.5～14岁儿童的屈光状态.资料表明:非斜视者的屈光不正随着年龄增长,远视的发生和程度逐渐减少而近视的发生和程度逐渐增加。双眼屈光不正性弱视者,中、量度弱视的高、中度远视和近视比轻度弱视者多.单跟屈光不正性弱视者,高、中度远视和高度近视比非弱视眼的多.双眼内斜视性弱视的不同年龄和不同程度弱视的屈光分布无显著差异.单眼斜视性弱视的屈光分布与非弱视眼比,无显著差异.本文结果揭示屈光不正性弱视与高度屈光不正有关;眼位偏斜可能为斜视性弱视的主要原因.

The refractive status of 3 099 children was analyzed. The result showed that the incidence and degree of hyperopia decreased gradually and those of myopia increased along with the growing up of children in ametropia. In binocular refractive amblyopia, high and medium hyperopia and myopia in severe and medium amblyopia were significantly more than those in mild amblyopia. In monocular refractive amblyopia, high and medium hyperopia and high myopia in the amblyopic eyes were more than those in the nonamblyopic eyes. The refractive status of binocular esotropic amblyopia had no significant difference in various ages and degrees of amblyopia. There was also no significant difference between the refractive status of the amblyopic and nonamblyopic eyes in monocular esotropic amblyopia. It was considered that refractive amblyopia was closely related to high ametropia and the deviation of the eye might be the main cause of strabismic amblyopia.
