Abstract
Abstract Introduction The 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 RetCam 3 wide-angle camera and also to study the variability of ROP diagnosis depending on the evaluator. Materials and methods The indirect ophthalmoscopy exam was performed by a paediatric ROP-expert ophthalmologist. The same ophthalmologist and a technician specialised in digital image capture took retinal images using the RetCam 3 wide-angle camera. A total of 30 image sets were analysed by 3 masked groups: group A (8 ophthalmologists), group B (5 experts in vision), and group C (2 ROP-expert ophthalmologists). Results According to the diagnosis using indirect ophthalmoscopy, the sensitivity (26–93), Kappa (0.24–0.80), and the percentage agreement were statistically significant in group C for the diagnosis of ROP type 1. In the diagnosis of ROP type 1 + type 2, Kappa (0.17–0.33) and the percentage agreement (58–90) were statistically significant, with higher values in group C. Conclusion The diagnosis, carried out by ROP-expert ophthalmologists, using the wide-angle camera RetCam 3 has proven to be a reliable method.
