Abstract
The aim of the present study was to examine the potential of machine learning for identification of isolated neurosensory retina detachment and retinal pigment epithelium (RPE) alterations as diagnostic criteria of central serous chorioretinopathy (CSC).
Material and methods. Patients with acute CSC in whom a standard ophthalmic examination and optical coherence tomography (OCT) using RTVue-XR Avanti (Angio Retina HD scan protocol, 6 × 6 mm) was performed were included in the study. 10-μm en face slab above the RPE layer was used to create ground truth masks. Learning aims were defined as identification of 3 classes of structural abnormalities on OCT cross-sectional scans: class 1 – subretinal fluid, class 2 – RPE abnormalities, and class 3 – leakage points. Data for each of the 3 classes included: 4800/1400 training/test images for class 1, 2000/802 training/test images for class 2, and 1504/408 training/test images for class 3. Unet-similar architecture was used for segmentation of abnormalities on OCT cross-sectional scans.
Results. Analysis of test sets revealed sensitivity, specificity, precision, and F1-score for detection of subretinal fluid of 0.61, 0.99, 0.99, and 0.76, respectively. For detection of RPE abnormalities sensitivity, specificity, precision, and F1-score were 0.14, 0.95, 0.94 and 0.24, respectively. For detection of leakage point sensitivity, specificity, precision, and F1-score were 0.06, 1.0, 1.0, and 0.12, respectively.
Conclusions. Thus, machine learning demonstrated high potential in the OCT-based identification of structural abnormalities associated with acute CSC (neurosensory retina detachment and RPE alterations). Topical identification of the leakage point appears to be possible using large learning sets.
