A More Engaging Visual Field Test to Increase Use and Reliability in Pediatrics
The majority of young children do not think that visual field (VF) testing of peripheral vision is similar to a game; therefore, it is not surprising that they have difficulty maintaining attention during VF testing and thus the…
