Use of retinal photography in the diagnosis of clinically significant macular edema (CSME)

Abstract

Abstract Purpose To determine the validity of the simple and stereoscopic retinal photography in the diagnosis of clinically significant macular edema (CSME). Methods Cross‐sectional observational study consisting of 420 eyes of patients with diabetic retinopathy, which was a combination of retinography (simple, light and stereoscopic aneritra), after expansion, to determine its validity in the diagnosis of diabetic macular edema. We calculated sensitivity, specificity, positive and negative predictive values and the correlation with the gold standard test (optical coherence tomography). The retinographs were evaluated by three experts and their results analyzed by the statistical program SPSS 15.0 Windows. Results For the analysis of the clinically significant macular edema( CSME), there were obtained sensibilities near to 80 % (color photographs 45 º, green 45 º, 30 º) and superior to 80 % (stereoscopic green 45 º, stereoscopic color 30 º, stereoscopic green to 30 º), reached the stereoscopic green photography 30 º, a sensibility of 92,5 %. The specificity was 90%. The positive predictive value was greater than 95% and the negative value greater than 90% with a coefficient of agreement (80%) and a degree of consistency with the benchmark of over 80%. Less than 5% of the retinographs were of poor quality. Conclusion The stereoscopic retinal photography to color of 45 º and 30 º, aneritra of 30 º and stereoscopic aneritra of 30 º offer a sufficient sensibility and specificity to be used in the diagnosis of clinically significant macular edema (CSME).
