Eligible population:

'All preterm infants <31 weeks, regardless of weight' and 'All preterm infants <1250 grams, regardless of gestation'.
The digital imaging of the retina will be done by the DRP trained nurses using a device called RetCam 24 - 48 hours prior to or after the BIO examination. 5-6 images per eye will be taken the images will be uploaded onto the computer database by the nursing staff. The image acquisition takes 10-15 minutes. DRP images are done as per the screening schedule. From the database images will be sent to the ophthalmologists for interpretation.
