目的:探索城、乡学龄前儿童视力低常现状,比较城、乡儿童视力低常患病率,弱视发生率,并从中找出影响儿童视力发育的原因,为临床早期干预提供科学依据。方法:对孝感市城区3~6岁8730名学龄前儿童和乡镇3~6岁2 150名学龄前儿童进行视力筛查,将单眼或双眼视力低于正常者,通知门诊复查,将矫正视力低于0.8,定为弱视。结果:城区视力低常患病率15.32%,乡镇视力低常患病率3.91%,城区与乡镇间存在统计学差异(P<0.001);城区弱视患病率5.37%,乡镇弱视患病率0.79%,存在统计学差异(P<0.001)。
Objective: To explore the prevalence of poor eyesight in preschool children in cities and townships, to compare the prevalence of low vision vision and amblyopia in urban and rural children, and to find out the reasons that affect the visual development of children and to provide a scientific basis for early clinical intervention. Methods: A total of 2,730 pre-school children aged 3 to 6 years old and 2,150 preschool children aged 3 to 6 years in Xiaogan City were screened for visual acuity. The visual acuity of monocular or binocular eyes was lower than normal. The corrected visual acuity At 0.8, set as amblyopia. Results: The prevalence of low vision in urban area was 15.32%, the prevalence of low vision in township was 3.91%, there was a significant difference between urban areas and townships (P <0.001); the prevalence of amblyopia in urban areas was 5.37%, the prevalence of amblyopia in townships was 0.79 %, There is a statistical difference (P <0.001).
