It is one of the most frequent problems of the visual health, whose prevalence increases in the equatorial latitudes. And it has a multifactorial etiology, relating some external factors, especially the exposure to RUV. The present research is a descriptive, explanatory and retrospective study. And it fulfilled the objectives: to describe the main clinical and epidemiological aspects of the pterygium in patients attended at the Manuel Ygnacio Monteros Hospital in 2015, characterizing the population epidemiologically, identifying the clinical characteristics of pterygium and describing the type of treatment used. Patients were selected according to the diagnosis of pterygium at the outpatient clinic of the Manuel Ygnacio Monteros Hospital from January to December 2015, excluding those with a pathology other than that mentioned. We studied 869 patients whose data were collected with a form containing the variables under study. The results indicated female superiority with 52%, the majority age group between 31 and 40 years old in 24% and urban residence in 57%. Workers were the most prevalent occupation with 33%, the main type of exposure was to ultraviolet radiation by 39%. Clinically the pterygium had a bilateral presentation in 49%, nasal area in 78%, grade II in 46% of cases and the most frequent symptom in consultation was conjunctival congestion in 63%. Pharmacological treatment was used in 65% of cases, using prednisolone in most of these cases, whereas conjunctival autograft was the most used surgical technique in the remaining 35%.
