>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 cryotherapyincreases the incidence of myopia but the degree of myopia induced by cryotherap y is low. |
