目的 :研究弱视在小学生中的发病率、屈光状态分布和主要影响因素。方法 :在全市视力不良的小学生中 ,用列镜筛选 ,再用扩瞳检影验光进行屈光测定 ,选择矫正视力≤ 4.9;眼科检查无器质性病变的弱视患者 ,分别检查注视性质、眼位、单视功能及询问填写调查表。并分别作统计学处理。结果 :在受检 6 36 90眼中 ,确诊弱视 12 0 5人 ,2 2 6 6只眼 ,患病率为 3.78% ;以屈光不正弱视为主 ,其中远视性弱视最高。弱视程度与屈光度、注视性质密切有关 ;其发生有多种因素。结论 :弱视是一种严重影响儿童视功能发育的眼病 ,屈光不正是造成弱视的主要病因 ,强调早发现、早治疗有重要的意义 ,建议在新生入学时即进行弱视筛选及防治
Objective: To study the incidence of amblyopia in primary school students, refractive status distribution and the main influencing factors. Methods: Among the pupils with poor eyesight in the city, they were screened with lens and then dilated pupil retinoscopy was used for refractive test. The corrected visual acuity was ≤ 4.9. The patients with amblyopia who did not have organic disease were examined with gaze, Bit, single visual function and inquiry to fill in the questionnaire. And for statistical analysis. Results: Among the 6 36 90 eyes examined, a total of 125 amblyopia and 2266 eyes were diagnosed. The prevalence was 3.78%. Amblyopia was the main cause of myopia, and hyperopia amblyopia was the highest. The degree of amblyopia and diopter, closely related to the nature of attention; its occurrence of many factors. Conclusion: Amblyopia is an eye disease that seriously affects the development of visual function in children. Ametropia is the main cause of amblyopia. Emphasizing the importance of early detection and early treatment, it is suggested that screening and prevention of amblyopia
