Among 249 patients, retinopathy of prematurity(ROP) developed in 36 patients(14.5%). 19 patients(528%) were stage 1, 4(11.1%) patients were stage 2, 11 patients(30.6%) were stage 3, 2 patients(56%) were stage 4 and there was no stage 5 ROP patient. 2. In gestational age, there was not statistically significant difference between normal lnfants and under-prethreshold stage group, but there were statistically significant differences between normal or under-pretheshold stage group and pretheshold or theshold stage group and was not stastically significant difference between prethreshold stage and threshold stage. 3. In birth weight, there was statistically significant difference between normal group and under-prethreshold stage group and also be statistically significant differences between normal or under-prethreshold stage and pretheshold or threshold stage group but there was not statistically significant difference between prethreshold stage and threshold stge. 4.
