Based on existing image databases of diabetic patient for screening Diabetic Retinopathy (DR), and using the information about suspicion of glaucoma and Age related Macula Degeneration (AMD), this work involves the development of two algorithms to assess the presence of glaucoma and AMD.
Based on Artificial Intelligence (AI) solutions, glaucoma and AMD are detected using two distinct sets of convolutional neural networks (CNNs). The solution is a complement of an existing solution that automatically assesses the quality of the photography, and DR.For training and evaluation purposes, 20 218 images with AMD labels and 62 260 images with glaucoma suspicion labels, with multiple ethnics and different acquisition devices, were collected in Paris Hospitals. For testing the glaucoma detector, a subset of the Chinese REFUGE database was also used. Unlike competing AI solutions, CNNs are jointly trained in such a way they are complementary with one another. Thanks to a proposed heatmap generation method, patterns that each CNN detects can be overlaid on images for pathology visualization.
The algorithm for AMD detection is capable of detecting early signs of AMD such as drusen, as well as geographic atrophies and choroidal neovascularization. It also provides confidence levels for AMD. The sensitivity is 96.54% and the specificity is 95.40%. The system has an area under the ROC curve (AUC) of 0.9916. Achieved results are better than those obtained in two previous large studies. In the case of glaucoma, the sensitivity is 92.50% and the specificity is 86.94%. The algorithm also provides a confidence level for the suspicion of glaucoma. The system has an AUC of 0.9644. Achieved results are similar to those already published.
The proposed jointly trained CNN set improves fully automatic detection of referable DR with the automatic determination of suspicion of glaucoma and AMD. It is a big step forward in the detection of pathologies in the retina. It provides more accurate predictions in less than a second using a fast GPU graphic processor. All algorithms are CE marked to provide a fully automated system to be used in hospitals, private practices, and mass screening networks.
