According to Jeff Locke, MSc, OC(C), COMT, former co-chair of the Canadian Orthoptic Society, the pediatric eye examination may be progressed with numerous small steps. Locke, an orthoptist/teacher and group chief in IWK Health’s Visual Electrophysiology Laboratory in Halifax, Nova Scotia, Canada, mentioned the problem of refining pediatric eye exams. They can streamline matters and make the examination 1% better via way of means of being extra capable at assessing visible acuity, checking for binocular single vision, and via way of means of understanding what visual electrophysiology can do on this age group, Locke stated.

For vision to be normal, stimuli should travel thru our optics to the retina, the retina to the optic nerve, and the optic nerve to the cortex. Acuity may be primarily based totally on which components of the pathway are stimulated, explains Locke. To benchmark 20/20 vision in a baby, the pediatric eye examination types and the visual acuity to be measured should be changed, Locke said. In pre-verbal children, forced-choice preferential viewing (FPL) tests like Cardiff and Teller aren’t the maximum correct at detecting and dealing with amblyopia, he stressed. Locke cited that it’s clean to get complacent with FPL tests and stop documenting those previously learned tests. As an infant achieves extra visual milestones as they age from new child to one year, the medical doctor might also additionally carry out extra complex tests. The task with visual electrophysiology in pediatrics is that maximum tests require a baby or little one below evaluation to work collectively to attain accurate results, making the checks not usually practical, except for the electroretinogram (ERG), which may be performed below sedation, Locke said.

Visual evoked potentials (VEPs) offer a goal measure to the cortex, however anomalies at any level of the optical pathway (optic, macula, optic nerve, optic pathway) can cause VEP pathology, Locke cited. Another medical gem he supplied is that assessors keep away from turning their backs on their pediatric patients. Locke advised setting the computer display screen in which records are entered which will preserve a view of the assessed infant.
