Purpose: To determine if monoscopic photography may serve as a useful screening tool for the detection of clinically significant macular edema (CSME). Methods:Two readers, a fellowship trained retina specialist and a professional retinal photography reader, were asked to evaluate previously recorded retinal photographs from100 eyes in a masked, randomized fashion. At separate sittings the readers were first presented 100 monoscopic photographs in a random order and asked to evaluate for probable CSME based on ETDRS criteria. A week later, at separate sittings, the readers were presented the same photographs in random order as stereoscopic. The readers were asked again to categorize the photographs as CSME or not. These stereoscopic readings served as the gold standard for each reader. Results: Each reader’s monoscopic readings were evaluated for sensitivity and specificity as compared to their stereoscopic readings. The readers’ results were also evaluated in combination. Reader one had a sensitivity of 0.93 and a specificity of 0.77 and reader two had a sensitivity of 0.88 and a specificity of 0.94. In combination the readers had a sensitivity of 0.91 and a specificity of 0.86. The correlation between the readers was also evaluated for their stereoscopic readings and monoscopic readings. They correlated on 0.76 of the stereoscopic readings and 0.92 of monoscopic readings. Conclusions: While the sensitivity and specificity required for an effective screening method is a debatable subject, these results indicate that the use of monoscopic retinal photography could be utilized as an accurate screening tool for CSME.
