4 Ophthalmic Pathology and Intraocular Tumors
Part II: Intraocular Tumors: Clinical Aspects
Chapter 20: Ocular Involvement in Systemic Malignancies
The most common tumor occurring in the adult eye is a secondary metastatic tumor. This generally presents as a choroidal mass, disseminated from a carcinoma elsewhere in the body.
The most common intraocular site for metastatic tumors is the posterior choroid, owing to its rich blood supply.
Lymphoma can affect a single ocular tissue or multiple tissues, from the ocular adnexa to various parts of the eye, and there may be systemic involvement.
Ocular involvement in leukemia is frequent and most commonly manifests clinically as retinal hemorrhages and cotton-wool spots.
