Identifying Retinal Features Using a Self-Configuring CNN for Clinical Intervention

Retinal diseases are leading causes of blindness worldwide, necessitating accurate diagnosis and timely treatment. Optical coherence tomography (OCT) has become a universal imaging modality of the retina in the past 2 decades, aiding in the diagnosis of various retinal conditions. However, the scarcity of comprehensive, annotated OCT datasets, that are labor-intensive to assemble, has hindered the advancement of artificial intelligence (AI)-based diagnostic tools.

To address the lack of annotated OCT segmentation datasets, we introduce OCTAVE, an extensive 3D OCT dataset with high-quality, pixel-level annotations for anatomic and pathological structures. Additionally, we provide similar annotations for four independent public 3D OCT datasets, enabling their use as external validation sets. To demonstrate the potential of this resource, we train a deep learning segmentation model using the self-configuring no-new-U-Net (nnU-Net) framework and evaluate its performance across all four external validation sets.

The OCTAVE dataset collected consists of 198 OCT volumes (3762 B-scans) used for training and 221 OCT volumes (4109 B-scans) for external validation. The trained deep learning model demonstrates clinically significant performance across all retinal structures and pathological features.

We demonstrate robust segmentation performance and generalizability across independently collected datasets. OCTAVE bridges the gap in publicly available datasets, supporting the development of AI tools for precise disease detection, monitoring, and treatment guidance. This resource has the potential to improve clinical outcomes and advance AI-driven retinal disease management.
