ABSTRACT
We measured the axial length according to age in the eyeball of premature infants who were born at our hospital. Our patients were 36 weeks old below in conceptual age, 38 eyes in 19 males, 28 eyes in 14 females. total 66 eyes in 33 premature infants. And we examined the axial length using the A-mode of the LTZ/SSW-48. 7MHz for 1 month at each weeks. The results were as follows: 1. The mean axial length was 16.56mm (15.40-17.80) at 1st week of life. 16.82mm (15.43-17.95) at 2nd week, 17.01mm(15.71-18.01) at 3rd week, 17.04mm (15.72-18.24) at 4th week. 2. The mean axial length of 1st week was 16.77mm in male, 16.34mm in female; at 2nd week, 16.91mm in male, 16.72mm in female; at 3rd week, 17.09mm in male, 16.90mm in female; at 4th week, 17.12mm in male, 16.96mm in female and they did not show significant difference between male and female premature infants.
