Abstract
Purpose :
To compare the impact of retinopathy of prematurity (ROP) screening examination between the Optos ultra-widefield retinal-imaging camera and conventional binocular indirect ophthalmoscopy (BIO) using cardiorespiratory indices as a measure of distress.
Methods :
A prospective randomised cross over study. Thirty-five ROP screening examinations with BIO and the Optos ultra-widefield retinal-imaging camera were performed for 19 premature infants with a birth weight of ≤1500g and/or gestational age of ≤32 weeks. Cardiorespiratory indices (change in heart rate, oxygen saturation, and respiratory rate) were recorded at four points: before, during and immediately after screening and 10 minutes after examination.
Results :
The Optos ultra-widefield retinal-imaging camera caused significantly greater oxygen desaturation than conventional BIO during screening as compared to the BIO (p value <0.05). Screening examination with the Optos ultra-widefield retinal-imaging camera took significantly longer (p value <0.0001).
Conclusions :
Screening for ROP with the Optos ultra-widefield retinal-imaging device is associated with a higher stress-related response than conventional indirect ophthalmoscopy.
