To investigate the characteristics of hypermetropic children whose visual acuity (VA) is declined or accompanied by esotropia.
One hundred and ninety children were given optometry, strabismus degree and binocular vision measurement.
Declined VA appeared in 170 children, while esotropia occurred in 173. Sixty-one got binocular single vision, 17 had fusion function, and 11 had stereoaculty. Spherical equivalent had a linear relationship with VA (P < 0.01), but not with the strabismus degree (P > 0.05). The influence factors of binocular vision were age of discovery, VA and the strabismus degree, while the stereoaculty was influenced by the strabismus degree, spherical equivalent and VA.
Low VA and strabismus are the most common complaint in children. Ametropia and strabismus do great harm to juvenile binocular vision, and stereoaculty is damaged seriously. We suggest an early examination of visual function in children.
探讨视力下降或伴有内斜视的远视儿童的特点。
对190名儿童进行验光、斜视度及双眼视觉测量。
170名儿童出现视力下降，173名儿童发生内斜视。61名获得双眼单视，17名有融合功能，11名有立体视。等效球镜度与视力呈线性关系（P<0.01），但与斜视度无关（P>0.05）。双眼视觉的影响因素为发现年龄、视力和斜视度，而立体视受斜视度、等效球镜度和视力影响。
视力低下和斜视是儿童最常见的症状。屈光不正和斜视对青少年双眼视觉危害极大，立体视严重受损。建议对儿童进行早期视功能检查。
