Abstract:
The ocular tissues can be the site of a number of malignant tumors in adults and geriatric patients. In addition to posing a threat to the patient's life, these tumors can cause severe visual loss or blindness. Therefore, the primary care clinician should be capable of prompt diagnosis of the various malignant ocular tumors and be prepared to refer the patient for appropriate management. This article provides a photographic guide to the most common primary and secondary malignancies that can affect the eyelid, conjunctiva, intraocular structures, and orbit in the geriatric patient.
