The authors performed cycloplegic refractions in 180 eyes of 99 premature infants at the age of 6 months to evaluate the incidence and the degree of myopia according to the development and disease course of retinopathy of prematurity (ROP) and to investigate the effect of cryotherapy on the refractive error. The incidences of myopia were not different between premature infants without ROP and premature infants with spontaneously and totally regressed ROP (36.3%, 25.5%), and the degrees of myopia were low in both groups (-1.76 D, -2.25 D). In premature infants with totally regressed ROP after cryotherapy, the incidence of myopia was high (75.5%) but the degree of myopia was low (-3.03 D). In premature infants with cicatricial ROP, cryotreated or not, both the incidence and the degree of myopia were high (93.9%, -5.50 D). It is suggested that cryotherapy increases the incidence of myopia but the degree of myopia induced by cryotherapy is low.
作者对99名6个月大的早产儿的180只眼睛进行了睫状肌麻痹验光，以根据早产儿视网膜病变（ROP）的发展和病程评估近视的发生率和程度，并研究冷冻疗法对屈光不正的影响。无ROP的早产儿和ROP自发完全消退的早产儿的近视发生率无差异（分别为36.3%和25.5%），两组的近视度数均较低（分别为-1.76 D和-2.25 D）。冷冻治疗后ROP完全消退的早产儿中，近视发生率较高（75.5%），但近视度数较低（-3.03 D）。在有瘢痕性ROP的早产儿中，无论是否接受冷冻治疗，近视的发生率和度数均较高（分别为93.9%和-5.50 D）。提示冷冻疗法会增加近视的发生率，但冷冻疗法所致的近视度数较低。
