Modern imaging techniques greatly facilitate and supplement the clinical evaluation of patients with visual symptoms. The technical aspects of ultrasound, CT, and MR imaging are described as well as their clinical applicability and limitations. Numerous examples of abnormalities on imaging studies are presented and discussed based on localization of the lesion. Furthermore, imaging methods not yet perfected may bring additional options for imaging in the future. Currently, many of the techniques are complementary and can be used appropriately if the limits and advantages of each method are kept in mind.
