Abstract
Abstract Purpose Detecting and monitoring Microcystic Macular Edema (MME) in Optical Coherence Tomography (OCT) images is vital for early diagnosis of Diabetic Macular Edema (DME), a leading cause of blindness in developed countries. However, detecting MME remains challenging due to its fuzzy boundaries and diffuse nature. In this work, we propose a novel fully-automatic methodology based on multi-stage regional learning to successfully detect and visualize MME in OCT images. Methods Our work is divided into two main stages: the first stage coarsely identifies general DME accumulations in the innermost retinal layers. On the other hand, the second stage precisely detects MME within the reduced search space. These detections are then used to generate intuitive confidence maps. Results Our approach achieves a mean confidence of 0.9618 ± 0.0518 per MME pixel, demonstrating consistent and strong detections. This robust methodology facilitates early diagnosis of MME, independent of clinicians’ subjectivity, and has the potential to significantly impact the quality of life of patients. Conclusion Our work represents a significant advancement in the automatic analysis of complex retinal pathologies.
