Published a paper suggesting an association between time spent outdoors and peripapillary choroidal thickness

A one-year observational study examining schoolchildren’s time spent outdoors and changes in choroidal thickness around the optic disc, in which our company participated as a joint researcher, has been published in an international scientific journal. The study confirmed an association in which children who spent more time outdoors showed changes toward increased choroidal thickness in specific regions.
