Normative ERG, VEP values hold keys to assessing children’s visual system maturation

In both infants and schoolchildren, normative electroretinogram and visual evoked potential values are important factors in differentiating maturation of the visual system from pathological processes, according to a study.

Jelka Brecelj, at the University Eye Clinic in Ljubljana, Slovenia, conducted a literature review and found pediatric electroretinogram age-related changes in infants were seen as a decrease in latency and in schoolchildren as a decrease in amplitude. Pediatric visual evoked potentials (VEP) age-related changes in infants were seen as a decrease in latency, an increase in amplitude and the development of the waveform. Schoolchildren showed more gradual VEP changes, with a decrease in latency and amplitude and a transformation of the waveform.

The report is published in the November issue of Documenta Ophthalmologica.
