Short ReportEvaluation of artificial intelligence-based telemedicine screening for retinopathy of prematurity
Section snippets
Methods
Institutional Review Board approval was obtained at the Oregon Health & Science University, Portland, to retrospectively evaluate images from an existing ROP screening telemedicine program at Salem Hospital, Salem, Oregon. We included all subjects who met ROP screening criteria between September 2015 and June 2018 and had one or more telemedicine examination. All subjects had wide-angle retinal images taken by a neonatal nurse practitioner trained to use the RetCam (Natus Medical Incorporated,
Results
A total of 81 subjects met inclusion criteria (summarized in Figure 1), and 613 telemedicine eye examinations were analyzed. The mean (with standard deviation) number of telemedicine examinations for each infant was 3.8 ± 2.3 (range, 1-10). The mean postmenstrual age (PMA) at birth for included infants was 29.2 ± 2.1 weeks, with mean weight at birth of 1240 ± 235 g. Four eyes of 2 patients (2%) developed RR-ROP during telemedicine screening. Mean age for infants requiring transfer was 25 weeks;
Discussion
These results demonstrate proof of concept that AI may have a role in the screening of patients at risk for ROP. This study has several limitations. Our sample size was limited by actual ROP screening needs at a community hospital over 3 years, and may or may not be representative of other ROP screening populations. We included all image encounters in the relevant time period, and both image quality and field of view of the manually selected images were variable. Further work is needed to

2021, Biocybernetics and Biomedical EngineeringCitation Excerpt :The clinicians often recommend initial stage ROP screening for premature babies having low birth weight and who are born before 31 weeks of gestation. As tele-medicine based diagnostics are becoming wide spread, the amount of images that needs to be screened are too high and manual examination of these images become very difficult [3,4]. Recent advancements in neonatal care increased the survival rate of low birth weight preterm infants.
