Imaging the intraocular tumor is multi-modal, multi-purposed, evolving and essential in the detection, diagnosis and surveillance of intraocular tumors. The most useful modalities for imaging intraocular tumors are drawing, photography, ultrasound and optical coherence tomography. A primary purpose of imaging the intraocular tumor is to document its precise appearance (and that of its secondary effects) at a point in time, thus permitting sequential images to accurately document change. However, an equally important reason for imaging is to gather diagnostic information that cannot be obtained from ophthalmic examination alone. The specific utility of each available imaging modality depends on the patient, tumor and ability of the clinician to interpret the data produced.
