Fig. 1. Risks of total cases of ocular melanomaa, choroidal melanoma, ciliary body/iris melanoma and conjunctival melanoma and melanoma in other sites combinedb associated with an increase of 10 mW/m² in ambient UVR in the Surveillance, Epidemiology, and End Results Program, 2000–2019.

^aTotal ocular melanoma included anatomical sites of choroid, ciliary body/iris, conjunctiva, eye NOS, overlapping region of eye and adnexa, orbit NOS, retina, cornea, and lacrimal gland. ^bMelanoma in other sites combined included anatomical sites of eye NOS, overlapping region of eye and adnexa, orbit NOS, retina, cornea, and lacrimal gland. Adjusted for age, sex, race and ethnicity, year of diagnosis, and registry’s population size that was categorised into quartiles using census-based population size to create four roughly equal categories (Q1: Iowa, Utah, Seattle (Puget Sound) Registry, Atlanta (Metropolitan) Registry, Rural and Greater Georgia Registries, San Francisco-Oakland SMSA Registry, San Jose-Monterey Registry, Los Angeles Registry, and Hawaii; Q2: Louisiana, Illinois, and Greater CA Registry; Q3: New Mexico, New York, Connecticut, and New Jersey; Q4: Texas, Idaho, Massachusetts, and Kentucky). Note: Square area is proportional to number of cases.10 mW/m² corresponds to about a 770-kilometer (~478 mile) north-south distance on the East Coast of the United States.
