【摘要】 目的了解大学生近视眼周边视网膜变性患病情况及其与近视屈光度、眼轴长度的关系,为进行相关健康教育提供依据。方法随机抽取178位屈光状态为近视的大学生,进行角膜曲率、睫状肌麻痹验光、眼压、眼轴、Goldmann三面镜检查。结果 45.21%的大学生近视患者检出不同类型的周边视网膜变性,其中格子样变性检出率为8.98%。有格子样变性、视网膜裂孔的近视大学生眼轴长度长于无此类视网膜变性者(P值均<0.05)。结论大学生近视患者的周边视网膜变性检出率较高,且随着近视屈光度及眼轴长度的增加而增高。更多还原

【Abstract】 Objective To determine epidemiological characteristics of peripheral retinal changes in undergraduates with myopia(spherical equivalent≤-0.50D) and to investigate the relationship with severity of myopia,axial length or the depth of vitreous and the retinal lesions in myopia.Methods A cross-sectional survey was conducted in 178 undergraduates with refractions equal to or less than-0.50D.Examinations included keratometry,cycloplegic refraction,intraocular pressure measurement,A and B scan ultrasonography,and retinal examinations by indirect ophthalmoscopy with scleral indentation and Goldmann three-mirror contact lens examination.Results Prevalence of peripheral retinal changes in myopic undergraduates was 45.21%.Prevalence of lattice degeneration was 8.98%.Positive correlations were found between axial length and the lesions of lattice degeneration,retinal hole and retinal detachment(P<0.05).Conclusion Peripheral retinal degenerations were very common among Chinese myopic undergraduates,and the severity was highly correlated with diopters of myopia,axial length.更多还原
