The relationship between outdoor exposure and myopia on university students, measured by conjunctival ultraviolet autofluorescence (CUVAF)

Purpose: The purpose of this study was to analyse whether outdoor (OD) exposure could exert a protective effect against the development of myopia and HM, in two different cohorts of university students that differ in the time of OD activities in their study programs. Moreover, CUVAF, as an objective...

Description
Summary:Purpose: The purpose of this study was to analyse whether outdoor (OD) exposure could exert a protective effect against the development of myopia and HM, in two different cohorts of university students that differ in the time of OD activities in their study programs. Moreover, CUVAF, as an objective measure of time spent outdoors, was also investigated in this cohort. Methods: A cross‐sectional observational study was carried out using two different cohorts of students, one of medical students (MS) and the other of environmental science students (ESS). All participants underwent an automatic objective refraction, axial length measurement, colour fundus photographs, and CUVAF area (BAF module on the Heidelberg Spectralis HRA + OCT). All the participants filled out a questionnaire of life style and myopia history. For all statistical analyses, corrected p values
