形觉剥夺在儿童近视中的表达

目的:通过调查处于生长发育期的儿童由于各种原因的形觉剥夺会否造成双眼在近视发生、发展中的不一致,从临床层面上证实形觉剥夺性近视,揭示近视发病的环境因素和机制,从而采取有效措施进行防治。方法:抽取门诊近视患儿114例,均常规行视力、眼位、主导眼、眼底、裂隙灯、规范的散瞳检影等检查,并通过问诊了解家族史及是否存在剥夺因素。比较双眼的视力、屈光度,并就形觉剥夺眼与屈光度的高低进行相关性统计分析。结果:双眼视力(P=0.000)及屈光度(P=0.006)均存在显著性差异,即形觉剥夺眼与双眼屈光度高者相关(P=0.005)。结论:处于生长发育期的儿童由于各种原因的单眼形觉剥夺可以造成双眼近视发生不一致,剥夺眼近视发生早,屈光度高。应引起重视并积极采取有效措施进行早期干预。

Expression of form deprivation in children myopia

AIM:To investigate whether form deprivation due to various reasons in the children of growth and development stage will result in inconsistent occurrence and development of myopia in both eyes,and confirm form deprivation myopia from the clinical level, and to reveal the environmental factors and mechanisms of myopia to take effective measures of prevetion.METHODS:Totally 114 myopic children were selected for regular visual acuity, eye position, dominant eye, fundus, slit lamp, and standardized mydriatic retinoscopy and other tests, and understanding their family history and whether there was deprivation factors.Binocular vision and refraction were compared, and statistical analysis was done according to the form deprivation eye and diopter.RESULTS: Binocular visual acuity (P=0.000) and refraction (P=0.006) were significantly different, and form deprivation eye was correlated with binocular high refraction (P=0.005).CONCLUSION: Monocular form deprivation due to various reasons in the children of growth and development stage can cause inconsistent myopia of both eyes. The earlier the deprived eyes developed myopia, the higher the refractive error. We should pay attention and take effective measures for early intervention.
