ABSTRACT
Cancer in the eye can be primary or secondary from another source in the body. The most common primary tumors are pigmentary, and they can be found in the uveal or melanin containing structures, namely the choroid, iris and ciliary body. Other tumor types include retinoblastoma, which is derived from retinal cells and found in children. Tumors of significant size can also create an accompanying retinal detachment, vitreous/retinal hemorrhage and exudative changes. Wide-field imaging has the added benefit of a greater amount of depth of field; this enables an elevated tumor to be in focus at the same time the rest of the retina is sharp. Stereo imaging can be helpful in both angiography and color documentation to appreciate the depth of any lesions, as well as to delineate secondary retinal detachments. By reducing the distance between the camera and the patient's eye through applanation, we are able to achieve a wide-angle view of the retina.
