| dc.description | Pterygium is an eye condition in which abnormal tissue grows over the conjunctiva and, in some cases, extends toward the cornea, potentially affecting vision over time. While is exact cause remains unknown, it has been linked to prolonged exposure to environmental factors such as solar radiation, dust, wind, and low humidity. These conditions are especially common among agricultural workers, particularly in tropical climates and rural areas. This research aims to examine how environmental conditions influence the prevalence of pterygium among agricultural workers in the Delia Cristina sector, located in the La Unión parish, Babahoyo canton, during the period from October 2024 to April 2025. A quantitative approach was used to conduct this study, employing a relational, observational, and explanatory design. The research was non-experimental, cross-sectional, and correlational. The sample consisted of 100 agricultural workers aged 30 to 50, selected to assess the impact of environmental factors on the development of pterygium. Data collection was carried out through surveys and observations. The results revealed a high prevalence of this ocular condition, with men being the most affected due to their greater exposure to solar radiation and other environmental elements associated with outdoor agricultural work. In conclusion, prolonged exposure to certain environmental factors- particularly UV radiation, wind, dust, and climate variations- plays a significant role in the development of pterygium. Additionally, a lack of awareness regarding prevention was identified among the population, highlighting the need to implement educational strategies and promote the use of protective eyewear to mitigate the impact of this condition. | es_ES |

| dc.description.abstract | El pterigión es una afección ocular en la que un tejido anómalo crece sobre la conjuntiva y, en algunos casos, avanza hacia la córnea, lo que puede comprometer la visión con el tiempo. Aunque no se conocer con exactitud qué lo causa, se ha asociado a la exposición constante a factores ambientales como la radiación solar, el polvo, el viento y la falta de humedad. Estás condiciones son especialmente frecuentes en quienes trabajan en el campo, sobre todo en regiones de clima tropical y áreas rurales. Esta investigación busca analizar cómo las condiciones ambientales influyen en la frecuencia del pterigión entre los trabajadores agrícolas del sector Delia Cristina, en la parroquia La Unión, cantón Babahoyo, durante el periodo comprendido entre octubre 2024 y abril 2025. Para llevar a cabo esta investigación, se empleó un enfoque cuantitativo con un diseño relacional, observacional y explicativo. El estudio fue de tipo no experimental, transversal y correlacional. La muestra estuvo compuesta por 100 trabajadores agrícolas, con edades entre 30 y 50 años, seleccionados para evaluar de qué manera los factores ambientales inciden en la aparición del pterigión. La recolección de datos se realizó a través de encuestas y observaciones. Los resultados reflejaron una alta prevalencia de esta afección ocular, siendo los hombres los más afectados debido a su mayor exposición a la radiación solar y otros elementos ambientales relacionados con su trabajo al aire libre. En conclusión, la exposición prolongada a ciertos factores del entorno, especialmente la radiación UV, el viento, el polvo, y las variaciones climáticas, juega un papel clave en el desarrollo del pterigión. Además, se evidenció un bajo nivel de conocimiento en la población sobre cómo prevenir esta condición, lo que resalta la importancia de promover estrategias educativas y fomentar el uso de medidas de protección visual para reducir su impacto. | es_ES |
