Retinal damage related to high-intensity light-emitting diode exposure: An in vivo study.

Introduction: The objective of this investigation was to evaluate the effects of high-intensity light-emitting diode (LED) light from a curing device on the retinas of Wistar rats.

Methods: Six male Wistar rats were used, and their ocular structures were the focus of this study. During the photostimulation of each animal, the right eye of the animal, considered the control sample, was covered with a removable polyvinyl chloride cap, and the contralateral eye, the experimental sample, was exposed to high-intensity LED light, 3200 mW/cm (VALO Ortho; Ultradent Products, South Jordan, Utah) for 144 seconds from a distance of 30 cm.
