Relación entre la Prevalencia de Patologías de la Conjuntiva en Pacientes que Consultan a la Clínica de Optometría de la Universidad Santo Tomás de Octubre de 1997 a Diciembre de 1998 vs Junio del 2018 a Junio del 2019, Atendiendo al Índice de Radiación Ultravioleta y Niveles de Ozono para el 2018 y 2019

Abstract

The present work aimed to compare the prevalence of conjunctiva pathologies in patients who consult the Optometry Clinic of the Santo Tomas University, in the periods of time from October 1997 to December 1998 and June 2018 to June 2019, having into account the ultraviolet radiation and ozone index for 2018 and 2019. Information was collected from the USTA clinical registry database in the period from June 2018 to June 2019 and compared with the degree work of the years 1997 to 1998. This research was carried out under an Ecological Study with an analytical temporal trend, where the UV index, ozone and conjunctiva alterations were compared. The population was selected under convenience sampling. The results showed the trend on the UV and ozone index of the period of time studied with the pathologies of the conjunctiva such as pterygium and degeneration and conjunctival deposits. A total of 326 patients with degeneration and conjunctival deposits and 242 patients with pterygium were found. In conclusion, the relationship of the pathologies could not be evidenced in the established time, because they are chronic, and the study time was very short. Taking into account UV indices and ozone levels, it was evidenced that there is a directly proportional relationship between them. It was determined that the highest prevalence of conjunctival pathologies was found in the 46–60-year-old age group and in the female sex in both investigations.
