Abstract:
We compared 40 twin and control groups(birth weights <2500gm, gestational ages <37 weeks or oxygen therapy) to analysis twins as a risk factor of ROP. control groups were consisted of group 1(40 patients) and group 2(40 patients). The former birth weight was similar to twin group and the latter gestational age was similar to twin group. The results were as follows; 1. The incidence of ROP was 37.5% in twin group, 10% in group 1 and 27.5% in group 2, The incidence of ROP in twin group was highter than control groups, and there was statistically significant difference in incidence between twin group and group 1(p<0.05). 2. The incidence of stage 2 or worse ROP was 18% in twin group, 10% in group 1 and 23% in group 2, There were no statistically significant difference among each groups(p>0.05). 3. In case-control study of other associated possible risk factors, twin group had significantly higher rate of premature rupture of membrane than group 1 and C-section and hypoxia than group 2(p<0.05).
