ARAGONES CRUZ, Belmary  y  ALEMANY MARTORELL, Jaime. Relation of ultraviolet radiation and primary pterygium. Rev Cubana Oftalmol [online]. 2009, vol.22, n.1. ISSN 0864-2176.

Pterygium is present worldwide but it is more common in dry warm climates and predominates in countries situated 0º and 30º on North and South latitudes. There are epidemiological pieces of evidence in experimental and observational population studies that confirm that ultraviolet radiation is the initial unleashing factor in occurrence of pterygium and a significant risk factor for its development. The physical and climate phenomena accounting for the pathogeny of pterygium are almost unknown. Pterygium epidemiology is a basic tool for identifying its incidence and prevalence. On the basis of this review, we intended to make reflections on pterygium as a marker of degree of insolation of the human body and to emphasize the importance of protection against possible exposure to ultraviolet radiations in the final outcome of pterygium surgery.

Palabras clave : Pterygium; albeit phenomenun; reflectivity; ultraviolet radiation.
