Abstract
IntroductionThe retinopathy of prematurity (ROP) is a potentially avoidable cause of blindness in children. The advances in neonatal care make the survival of extremely premature infants, who show a greater incidence of the disease, possible. The aim of the study is to evaluate the reliability of ROP screening using retinography imaging with the RetCam3 wide-angle camera and also study the variability of ROP diagnosis depending on the evaluator. Material and methodsThe indirect ophthalmoscopy exam was performed by a Pediatric ROP-Expert Ophthalmologist. The same ophthalmologist and a technician specialized in digital image capture took retinal images using the RetCam3 wide-angle camera. A total of 30image sets were analyzed by 3 masked groups: groupA (8 ophthalmologists), groupB (5 experts in vision), and groupC (2 ROP-expert ophthalmologists). ResultsAccording to the diagnosis using indirect ophthalmoscopy, the sensitivity (26-93), Kappa (0.24-0.80), and the percent agreement were statistically significant in group C for the diagnosis of ROP Type1. In the diagnosis of ROP Type1+Type2, Kappa (0.17-0.33) and the percent agreement (58-90) were statistically significant, with higher values in groupC. ConclusionThe diagnosis, carried out by ROP-expert ophthalmologists, using the wide-angle camera RetCam3 has proved to be a reliable method.
