The demographic data included patient age at diagnosis (years), sex, and race/ethnicity (white, African American, Hispanic, Asian, Native American, Middle Eastern, and Asian Indian). A history of skin, orbit, or brain melanoma was noted. The following clinical data were obtained: intraocular pressure, ocular or oculodermal melanocytosis (present or absent; herein referred to as oculo[dermal] melanocytosis to include both ocular and oculodermal types), location of melanocytosis (temporal fossa, eyelid, conjunctiva, sclera, iris, choroid, or palate), laterality of melanocytosis with uveal melanoma (ipsilateral or contralateral), tumor laterality (unilateral or bilateral), general location of tumor epicenter (iris, ciliary body, or choroid), quadrant location of tumor epicenter (superior, nasal, inferior, temporal, or macula), clock-hour location of the tumor epicenter (1:00 to 12:00), anteroposterior location of tumor epicenter (macula, macula equator, equatorora serrata, ciliary body, or iris), distance of posterior tumor margin to optic disc margin and foveola (millimeters), largest tumor basal dimension and thickness (millimeters), tumor configuration (dome, mushroom, tapioca, or plateau), color (pigmented, nonpigmented, or mixed), Bruch membrane rupture, subretinal fluid, intraocular hemorrhage, and extraocular extension. Tumor basal diameter was measured using indirect ophthalmoscopy and ocular ultrasonography. Tumor thickness was measured by ocular ultrasonography. All findings were documented appropriately with anterior and/or posterior segment photography and color-coded fundus drawing, fluorescein angiography, and A-scan and B-scan ultrasonography.
