摘要早产儿由于出生时发育不成熟,与正常足月儿相比,更易发生屈光不正、视力损害等视觉发育异常.通过了解早产儿屈光的特点、视力发育的影响因素及早产对其中无早产儿视网膜病变(ROP)者屈光或视力发育的影响,建立严密的随访体系,早发现并及时采取适合早产儿视觉正常发育的临床干预或治疗措施,对减少早产儿视觉发育异常、提高患儿的视觉质量和生存质量有重要意义.就早产儿屈光情况及早产儿视力发育的影响因素进行综述.

abstractsBecause preterm infants are premature,the rates of refractive errors and visual abnormalities are significantly higher than those normal full-term infants.By understanding their refractive characteristics and the factors those affect visual development,meanwhile,recognizing that premature birth also plays a role in the refractive or visual development of preterm infants without retinopathy of prematurity (ROP),we can establish the strict follow-up system,then early detection and be early in time for premature children with clinical intervention or treatment which is beneficial for normal visual development.It is extremely important to reduce abnormal visual development in preterm children,and to improve the visual quality of patients and quality of life.This paper summarizes the researches of refractive and visual development in preterm infants.
