Utilizing human intelligence with artificial intelligence, we use machine learning of human loops to detect glaucoma fundus images.

To overcome the artificial intelligence (AI) black box dilemma to diagnose glaucoma damage, we applied a new convolutional neural network (CNN) of TrueColor confocal fundus images. With human-in-the-loop (HITL) data annotations, this CNN architecture neural network is useful not only for diagnosing glaucoma but also for predicting and locating detailed signs of glaucoma fundus, including: B. Splinter hemorrhage, glaucomatous optic nerve atrophy, vertical glaucomatous coupling, peripapillary atrophy and retinal nerve fiber layer defect (RNFL). The training was performed on a carefully selected private dataset of 1,400 high-resolution confocal fundus images. Of these, 1,120 (80%) are dedicated to training and 280 (20%) are dedicated to testing. We used a specially trained object detection method based on You Only Look Once version 5 (YOLOv5) to pinpoint the underlying condition. The 26 predefined conditions were annotated by a team of humans (composed of two glaucoma specialists and two

Application of mydriasis and eye steering in ultrawide field imaging for detecting peripheral retinal lesions in myopic patients

To compare mydriatic and eye-steering ultrawide field imaging (UWFI) with standard non-mydriatic UWFI examination in detecting peripheral retinal lesions in a myopic patient's cross-sectional observational study. 220 eyes from 110 myopia patients with known peripheral retinal lesions in at least one eye were recruited for Goldman 3 mirror contact lens examination. Using Optomap UWFI (Daytona, Optos, UK), non-mydriatic standard and eye-steering UWFI images were taken in the center and eye-steered in the up, down, nose, and temporal gaze directions. Standard and eye steering mydriatic UWFIs were recorded with a central line of sight and four different peripheral lines of sight. We compared the sensitivities of detecting peripheral retinal lesions at various UWFI settings. 141 (64.09%) eyes had peripheral retinal lesions. Sensitivity to detect low to high peripheral lesions is 41.84% (95% CI 33.62% to 50.54%) with standard non-mydriatic UWFI settings and 52.48% (95% CI 44, 08% to 60.7
