Photorefraction was performed in 96 cases(191 eyes) after instillation of tropicamide and cyclopentolate for the purpose of screening procedure. And then refraction was also carried out by retinoscope. From this comparison study, phtorefraction provided data which were very close to those obtained from the conventional retinoscopy.

The aims of the our study are investigation of the average value of the refraction, anterior chamber depth(ACD), axial length(AL), and the interrelationship of refraction, ACD, AL, weight and height of normal newborn infant. Objects of this study are 236 eyes of 118 normal newborn infants that have been examined with retinoscope under the cycloplegia and the axial length and anterior chamber depth have been measured by ultrasonogram. And so we gained following results. The average value of refraction(+1.85 +/- 1.86D), the average value of the AL(17.5 +/- 0.68mm) and the average value of ACD(2.62 +/- 0.21mm) did not show significant difference between male and female newborn infants. The correlation coefficient between AL and ACD. refraction and AL, weight and AL, and height and AL were 0.326(P<0.001), -0.305(0.001
0.1).
