Visual electrophysiology can inform the treatment of:
- Children suspected of hereditary retinal conditions
- Children who exhibit poor vision or poor visual behavior
- Children showing symptoms of nyctalopia, photophobia, or difficulty adjusting to light conditions
Diagnosis and prognosis at an early stage
Visual electrophysiology provides long-term monitoring and phenotyping of disease in infants and children. With the pediatric ERG/VEP, we can objectively assess the function of the rod and cone systems, as well as the visual pathways to the brain. The results, when interpreted with reference data, provide the information needed to diagnose conditions or monitor their progression.

Pediatric ERG
A recently developed pediatric ERG yields diagnostically accurate data in children without anesthesia. Young children can now forgo the full dark-adaption and skip dilation while still delivering quality functional results. Learn more about the pediatric ERG.
The ColorFlash produces bright flashes of light that stimulate a child’s retina from a distance. Animal sounds are built-in to attract your patient’s attention, while skin electrodes ease test compliance.
CPT codes: 92273, 95930
Pediatric ERG is possible without anesthesia
Electrophysiology on young children has typically required anesthesia, however, with the GOSH-ERG, children between the ages of 1-5 years of age can be tested while awake.
This ERG is faster than you may remember it!
- Reduced test time
- Skin electrodes
- No dilation
- No formal dark adaptation period
Visual acuity screening
Add an objective visual acuity assessment to your practice. With sweep VEP, you can determine the visual acuity of a child using VEP techniques. This method works well for children who are non-verbal or vision impaired.
Perform the sweep VEP technique using the LI-LCD monitor that can be added to any Diagnosys clinical system.
