title: [Reliability of retinal imaging screening in retinopathy of prematurity].
abstract: BACKGROUND
  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 study the variability of ROP diagnosis depending on the evaluator.
  
  
  METHODS
  The 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 RetCam 3 wide-angle camera. A total of 30 image sets were analyzed 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 percent 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 percent agreement (58-90) were statistically significant, with higher values in group C.
  
  
  CONCLUSIONS
  The diagnosis, carried out by ROP-expert ophthalmologists, using the wide-angle camera RetCam 3 has proved to be a reliable method.
