Brief Summary

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.

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Infants eligible for routine ROP screening using UK ROP screening guidelines (Any infant born at or before 32 weeks gestation and/or weigh 1500 grams or less).
  • Infants with parents who have conversational English and who can give written informed consent.

You may not qualify if:

  • Infants not eligible for routine ROP screening under UK ROP screening guidelines.
  • Infants who are deemed not well enough by a consultant neonatologist (SO) for retinal examination or retinal imaging.
  • Any premature infant with media opacities that prevents adequate visualisation of the retina.
  • Inability of the parents to understand verbal and written English.

Model Details: Each premature infant recruited into the study will undergo retinal imaging with the Optos ultra-widefield retinal imaging device as well as the gold standard method of examination with the binocular indirect ophthalmoscope. The order of the procedures to be carried out in each infant will be determined by randomisation via sealed envelopes prepared remotely by a member of the pilot team not involved in the recruitment of patients or their screenings.
