Age-related macular degeneration (AMD) and diabetic macular edema (DME) are vision-threatening pathologies for which optical coherence tomography (OCT) provides high-resolution three-dimensional imaging, facilitating comprehensive diagnostic evaluation. Three-dimensional (3D) visualization and precise 3D segmentation of lesions enable accurate assessment of morphology, dimensions, and spatial relationships, thereby enhancing clinical analysis and disease management. However, the lack of a 3D dataset for AMD and DME significantly limits the reliability, robustness, and applicability of deep learning-based 3D segmentation techniques in this field. Here, we present an OCT dataset comprising 224 volumetric images, including 122 for AMD and 102 for DME, annotated with pigment epithelial detachment and intraretinal fluid. We propose a novel 3D segmentation network based on the BiFormer Block, which employs Bi-Level Routing Attention to capture local context and long-range dependencies. Experiments demonstrated that the proposed dataset and network will facilitate the exploration and validation of novel 3D segmentation methods for AMD and DME.
