作为一个光学系统,角膜是人眼屈光系统的主要成分,眼散光也主要来自角膜。早在1890年,Javal就开始了关于眼散光与角膜散光的研究。此后,有人相继报道了这方面的研究结果。本文报告了我国儿童的眼散光与角膜曲率之间关系的调查结果。 对象与方法:本组共27例,54只眼,均为1991年暑假期间来视光门诊就诊的小学生。平均年龄9.4岁(3～15岁)。 首次门诊时作初步的常规检查和小瞳的屈光检查,然后给1％阿托品眼膏涂眼三天,再次屈光检查。屈光检查都是用视网膜检影法。第二次扩瞳检影验光后,给双眼分别作角膜曲率测定(Nidek角膜曲率计)。屈
As an optical system, the cornea is the main component of the human eye refractive system, astigmatism is also mainly from the cornea. As early as 1890, Javal began research on astigmatism and corneal astigmatism. Since then, some people have reported the results of this research. This paper reports the results of a survey of the relationship between astigmatism and corneal curvature in children in China. Subjects and Methods: A total of 27 cases in this group, 54 eyes, all of them were optometrists attending primary school students in the summer of 1991. The average age of 9.4 years (3 to 15 years old). For the first time outpatient routine routine examination and pupil refractive examination, and then to 1% atropine eye ointment for three days, again refractive examination. Refractive examination is the use of retinoscopy. After the second dilation retinoscopy retinoscopy, both eyes were measured for corneal curvature (Nidek keratometer). Qu
