Disorders of the visual pathway can be due to pathological processes that cannot be directly assessed or visualized by ophthalmological examinations. Cross-sectional diagnostic imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), are frequently used to further assess the visual pathway. This article provides an overview of the principles of CT and MRI for the anatomical and technical assessment of ophthalmological disease processes. Additionally, a brief overview regarding the endovascular diagnostics with digital subtraction angiography (DSA) and treatment of vascular disease processes, which can also impair the visual pathway at various points is provided.
