Vision loss can occur due to a variety of etiologies along the primary visual pathway. Understanding the anatomic organization of the visual pathway, which spans the globe to the occipital cortex, can help tailor neuroimaging to identify the cause of visual dysfunction. In this review, relevant anatomy and optimization of computed tomography and magnetic resonance imaging techniques will be described. This will be followed by a discussion of imaging findings related to pathologies at each functional anatomic level.

Non-traumatic subperiosteal orbital hematoma is a rare finding and uncommon cause of proptosis. Reported cases describe an association with increased venous pressure. However, it is important to note that there is also an association with sinusitis, which must be differentiated from subperiosteal abscess. This article describes the unique imaging features of subperiosteal hematoma in the setting of sinusitis, as well as the suspected pathophysiology.
