Focal aggregate of normal or near normal uveal melanocytes (FANNUM) of the choroid is a term the author has proposed to categorize small melanocytic choroidal lesions that are not detectably thicker than surrounding normal choroid by B-scan ocular ultrasonography. In this article, the author describes the clinical features of small melanotic choroidal lesions he categorizes clinically as FANNUMs and discusses the presumed compositional spectrum of such lesions. He explains why such lesions should not be categorized uniformly as small choroidal nevi. Lesions of this type are detectable in at least one eye of approximately 25% of lightskinned blue-eyed persons over the age of 50 years. They are frequently multifocal in the affected eye, bilateral, or both.
