Figure 8From: Automatic method of analysis of OCT images in assessing the severity degree of glaucoma and the visual field loss Block diagram of the algorithm proposed by the authors. The patient undergoes a fundus examination with the use of a tomograph and their visual field is measured with a perimeter. Then, the significance and correlation of the features obtained are calculated, thereby forming three classes. They are the basis for proposing a new analysis algorithm. After automatic determination of the layers RPE, ILM, RNFL and the cup and disk, the features w g (1), w g (2) and w g (3) are determined. In the final stage, the proposed BGA ratio and correlation with results obtained from perimetry are calculated.Back to article page
