The study evaluated three commercially available artificial intelligence algorithms for DR detection using two nonmydriatic fundus cameras. Participants underwent two-field, nonmydriatic fundus imaging with both cameras. Image quality and DR presence were independently assessed by masked human graders, including optometrists and a retina specialist. Diagnostic performance was measured using sensitivity, specificity, and positive and negative predictive values.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 272 images from 136 participants (mean age 67.7 years; 62% female) were analyzed. Human graders classified more than 97% of images as gradable, with DR detected in 47% of the images. AI-1 demonstrated the highest sensitivity (Forus: 97.5% (0.956\u20130.994); Intuvision: 81.7% (0.768\u20130.867)) but comparatively low specificity: 62.7% (58.6\u201366.8) and 53.8% (0.474\u20130.602). AI-2 displayed a balanced performance (sensitivity 80.0% and 77.0%; specificity 95.7% and 92.0%). AI-3 had a moderate sensitivity (73\u201380%) with the specificity ranging from 82% to 86%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
