目的 分析儿童原发性近视眼的特点。方法 ①对象 :流行病学调查发现的 50例 ( 3～ 7岁 )及临床就诊的 39例 ( 1～ 1 2岁 ) ,静态屈光均为近视眼。②观察指标 :远视力、近视力、屈光(用 1 %阿托品 )、眼底、角膜曲率、眼轴。结果 儿童近视眼多数为原发性 ( 82例 ) ,继发于其它疾病的有 7例 ,无明显性别差异。儿童原发性近视眼为先天性 ,眼轴多明显延长 ,长度与屈光度成正相关 ,角膜屈折力无明显病理意义。屈光度进行性发展 ,随年龄增加而加深 ,是日后成年期变性近视眼的主要组成。结论 儿童近视眼可分为原发性和继发性。其中主要为原发性变性近视眼
Objective To analyze the characteristics of children with primary myopia. Methods ① Subjects: Fifty cases (3-7 years old) and 39 cases (1-12 years old) who were clinically seen in the epidemiological survey were all myopic eyes. ② observation indicators: far vision, near vision, refraction (with 1% atropine), fundus, corneal curvature, axial length. Results The majority of children with myopia primary (82 cases), secondary to other diseases in 7 cases, no significant gender differences. Children with primary myopia as congenital, axial length was significantly longer, with a positive correlation between length and refraction, corneal refractive power no significant pathological significance. Progressive development of refraction, deepening with age, is the main component of future adult degenerative myopia. Conclusion Children’s myopia can be divided into primary and secondary. Mainly for primary degeneration myopia
