Descriptive epidemiology of ophthalmic and ocular adnexal non-Hodgkin's lymphoma

In this article, we provide an update on incidence rates of ophthalmic non-Hodgkin's lymphoma (NHL), in the context of other NHL, in the USA. We also provide population-based estimates of incidence and survival for ocular adnexal NHL, the most common form of ophthalmic NHL, for which descriptive patterns have not been previously reported. Ophthalmic and ocular adnexal NHL have unique incidence patterns, including equal rates among both genders, predominance among Asians/Pacific Islanders, and steady and rapid increases in the past few decades. Studies of international variations in the incidence of ocular adnexal NHL may provide clues as to the underlying mechanisms influencing its unique epidemiology.
