Early Detection and Prevention of Amblyopia and Visual Impairment Through Systematic Pediatric Vision Screening

"The standard examination for amblyopia screening consists of three steps:~A monocular visual acuity assessment using optotypes from the LEA scale, presented from the simplest to the most complex in front of each eye via an alternating occlusion mask.~A cover/uncover test, during which the child is required to fixate on an image A Lang I stereopsis test performed under binocular vision."

The examination with the virtual reality headset consists of three main steps: A monocular visual acuity assessment using optotypes from the LEA scale, presented from the simplest to the most complex in front of each eye via an alternating occlusion mask. The eye-tracking system analyzes fixation and the visual response of the stimulated eye. A cover/uncover test, during which the child is required to fixate on an image projected inside the headset. Eye movements are tracked to detect any deviations or abnormalities in ocular coordination. A Lang I stereopsis test performed under binocular vision, in which the child must identify three-dimensional images hidden within a virtual board. The eye-tracking system detects fixation on the images and allows evaluation of depth perception
