早产儿屈光状态和视力的调查研究

目的:观察和分析早产儿的屈光状态和视力发育情况。方法:对4～6岁早产儿156例312眼门诊进行视力和静态屈光检查并记录结果。结果:4～6岁早产儿156例312眼远视238眼(76.3%),近视15眼(4.8%),散光28眼(9.0%),正视眼31眼(9.9%),生理性远视所占的比例最大,各年龄远视比例有所不同,但都随着年龄的增长远视比例下降,正视和近视比例逐渐增加,视力正常率明显提高。结论:4～6岁早产儿屈光状态和视力发育与正常儿接近,随着年龄的增长,屈光状态有由远视向正视和近视发展的趋势。

Study of refraction state and visual acuity of the preterm infants

AIM:To observe and analyse the visual acuity and refraction state of the preterm infants.·METHODS:To observe the visual acuity and static refraction of the 156 preterm infants(312 eyes) 4 to 6 years old and record the results.·RESULTS:The clinical data of 156 preterm infants(312 eyes)were observed,76.3% is hypermetropia(238 eyes),4.8% is myopia(15 eyes),9.0% is astigmatism(28 eyes),9.9% is emmetropia(31 eyes),physiological hypermetropia is the largest type.With the increasing of age,the percentage of hypermetropia goes down,the percentage of emmetropia and myopia goes up,and the percentage of emmetropia increases obviously.·CONCLUSION:The refraction state and visual acuity growth of preterm infants is close to that of normal infants,with the increasing of age,it shows the trend that the refraction state develops from hypermetropia to emmetropia or myopia.
