We evaluated the systemic and ophthalmological aspects of 37 extreme premature infants with birth-weight of 1,000g or less. These 37 cases were seen among a series of 525 low birthweight infants ad-mitted to the neonatal care unit of our hospital during the foregoing 9 years (1975-1983).

There was a significant increase in the incidence of extreme premature infants since 1978. Ret-inopathy of prematurity (ROP) developed in all the 37 cases, of which the ROP was of Type II or Intermediate Type in 14 cases (38%).

We evaluated a total of 28 risk factors which might influence the occurrence and progression of ROP in these 37 cases. The duration of oxygen administra-tion and exchange blood transfusion were significant factors for the progression of Type II or Interme-diate Type of ROP. Other factors, including birth-weight, gestational period, PaO2 values, idiopathic respiratory distress syndrome and severity of anemia, were not significant.

Detailed and repeated ophthalmological care is essential in the early detection and management of ROP in order to prevent visual impairment.
