Abstract

Two hundred twenty premature infants who were inhalated 02 and under 2500mg birth weight or under 37 weeks of gestational age were examined from January 1990 to June 1991. We performed clinical analysis and results were as follows. 1. Thirty one infants (14.1 %) were diagnosed as retinopathy of prematurity. 2. Male patients were 17 (54.8%) and female patients were 14 (46.2%). There was no significant difference in incidence between male and female (X2=0.01, p>0.05). 3. The first examination was performed at 2.4 weeks cf life in average, and the retinopathy of prematurity was diagnosed at 4.8 weeks in average. 4. Stage 2 was detected in 10 patients (32.3%) and stage 3 was detected in 6 patients (19.4%). 5. Plus sign was found in 2 patients (19%) with stage 2 and 6 patients (100%) with stage 3. 6. The incidence of retinopathy of prematurity was highly associated with low birth weight (<1200gm), small gestational age (<30 weeks), and oxygen concentration (>or=60%). 7. Other associated possible risk factors were hyperbilirubinemia, idiopathic respiratoty distress syndrome, anemia, apnea and transfusion.
