温州市区视力不良小学生屈光状态及相关因素

目的：研究视力不良小学生屈光状态及近视眼发病的相关因素，方法：随机抽取温州市视力不良的小学生4696名（有效眼9392眼）进行扩瞳视网膜检影验光，填写调查表，调查各年级小学生屈光状态及其相关因素。结果：本组小学生视力不良以屈光不正为主，占79．7％，其中近视性屈光不正最多，占48．9％，其次是散光25.6％。随学习阶段上升，近视患病率逐渐增高，屈光参差患病率23．7％，弱视患病率以远视性屈光参差最高，达97．9％。近视眼发病与遗传因素（20．19％）及环境、体质因素有关。结论：在小学生中普查视力和屈光状态，以早期发现屈光不正和弱视，进行及时防治，对控制小学生视力不良有重要意义。

Analysis of refraction condition and related factors among primary students with visual anomalous in Wenzhou

This study is aimed to investigae the refractive status and related factors among the primary pupils whase uncorrected visual acuity is abnormal during the vision screen. Methods: 4696 primary pupils who have the uncorrect ed VA under 1. 0 during the screen were earelled as the subjects. The refractive status was detendned hy Cyclopedia retinoscopy. And other eye exams and opestiormaire were done as well. Results: It showed that the ametropia was the main cause for the uncorrted visual acuity(79. 7% ), of which myopia was the first(48. 9% ), and astigmatism the second (25. 6% ). The prevalence of myopia is increed with the schooling age. The prevalence of whsometropia was 23. 7 %. 97. 9% of amblyopia was due to hypermetropical whsomtropia. 20. 19% of myopia was asaseiated with genetic factors. The prevalence of visual problem was related to environmental and physical factors. Condndon: Eary detecti0n and management of the vision problem Play an important role in controlhng the development of visual anomalous.
