ARIAS DIAZ, Alejandro et al. Behavior of pterygium in terms of exposure to UV radiations and its histological changes depending on severity. Rev Cubana Oftalmol [online]. 2009, vol.22, n.2, pp. 51-58. ISSN 1561-3070.

OBJECTIVE: To asses the behaviour of diagnosed pterygium, taking into account exposure to UV radiations and the histological changes according to severity. METHODS: A cross-sectional descriptive study was performed on patients operated on at "Ramón Pando Ferrer" Cuban Ophthalmology Institute from pterygium from January to December, 2006. The sample was made up of 101 adult patients who underwent pterygium removal, and they were randomly selected regardless of age, sex and place of origin. RESULTS: Exposure to UV light was statistically related in a significant way with male sex, increase of age and level of impact according to the applied Chi-square test. CONCLUSIONS: The histological study did not show any difference since the same histological composition was found in the whole sample.
