ROP is a preventable cause of blindness in premature infants. It is routinely screened for by using an indirect ophthalmoscope, a scleral depressor, and a condensing lens. This method of screening can cause significant cardiorespiratory distress to infants. A new camera (Optos California) has recently been used to image infants with different severities of ROP. The Optos California is capable of capturing up to 200 degrees of retina in a single image without contact with the eye. The non eye contact nature of the Optos California may cause less distress to infants who are due a ROP screening examination. The present study is to compare the impact of ROP screening examination between the Optos retinal camera and conventional binocular indirect ophthalmoscopy using cardiorespiratory indices (such as heart rate, oxygen saturations, blood pressure, and respiratory rate) as a measure of distress.
