| Abstract |
|
The previous researches proved that the incidence of myopia in cryotreated retinopathy of prematurity[ROP]eyes is higher than that of non-treated ROP eyes. The authors compared refractive states, anterior-posterior axial length and other contributing factors of treated eyes with those of nontreated eyes at the same age group between 3~4 years old. In the cases of cryotreated group, the mean refractive error was -3.48 +/-4.02D. Among 42 treated eyes, 30 eyes became myopic[71.4%]. The mean axial length was 22.46 +/-1.43mm. The mean length of posterior segment was 15.53 +/-1.33mm. In contrast, the mean refractive error was 1.09 +/-1.04D in non-cryotreated group. Three eyes among 42 untreated eyes developed myopia [7.1%]. The mean axial length was 21.02 +/-1.17 mm. The mean length of posterior segment is 14.09 +/-0.97mm. We concluded that myopia could be developed in cryotreated ROP eyes by the elongation of eyeball, specifically of posterior segment. |
