Windows and blinking: techniques for enhanced ocular computed tomographic imaging.
Computed tomography (CT) has become an important diagnostic modality in the evaluation of ocular and orbital disease. A weakness of CT, however, is its inability to show clearly intraocular lesions that do not contain calcium. These images can be improved by the careful selection of window width and window level and by the use of a technique known as "blinking." The use of these enhancement techniques is illustrated in two cases of leukocoria in children.
