Prevalência de sintomas oculares e insuficiência de convergência em estudantes universitários

Abstract

Objective: To investigate the prevalence of ocular symptoms and convergence insufficiency (CI) in university students and the association with the use of near vision. Methods: This is a cross-sectional study, including university students from brazilian institutions, of both sexes, in which the self-administered questionnaire Convergence Insufficiency Symptom Survey validated for the Portuguese language (CISS-vp) was used. The data were collected through an electronic form available on the Google Forms platform, and for the statistical analysis, the GNU PSPP® Version 1.4.1 program was used. Results: A frequency of 13.4% of convergence insufficiency (CI) was obtained in the sample of 456 students. Regarding ocular symptoms, the most prevalent were: feeling the need to reread the same line of a text, tired eyes, difficulty remembering what you read, eye discomfort and drowsiness. There was no association between longer use of near vision and the presence of CI, but there was a greater presence of eye strain in university students who spend more time using electronic devices. Conclusion: It was found that most university students had ocular symptoms related to the use of near vision and a high prevalence of CI was found in the studied population. Still, the increase in the time of use of electronic devices is related to the presence of eye strain.
