Beijing Children’s Hospital is one of the very few medical institutions in China that conducts visual electrophysiological examinations of children’s eyes. The advanced German Roland electrophysiological examination high-end instruments, the efficiency and accuracy of its tests are among the leading ones in China. In particular, the addition of animated patterns to the tabletop stimulator’s surgical black-and-white checkerboard flip can effectively stimulate children’s interest and increase cortical excitability, overcoming the difficulty of children’s inattention during the examination and increasing the accuracy of the examination. The German Roland visual electrophysiology instrument uses the International Society for Clinical Electrophysiology of Vision (ISCEV) technical standards and a special signal amplifier for ophthalmology to perform international standard examinations. It can accurately detect functional changes in the optic nerve and retina, with short examination time and small systematic errors. The German Roland electrophysiological examination program is very comprehensive, including P-VEP, F-VEP, full-field ERG, P-ERG, multifocal ERG, EOG, and contrast sensitivity function. In addition, there is a unique objective visual acuity assessment function, namely Sweep VEP, which can automatically calculate the visual acuity value and provide an objective visual acuity data for children who cannot cooperate with the visual acuity examination, including children with cerebral palsy, at an early stage, which provides a basis for further ophthalmic treatment. Electroretinogram (ERG) is the sum of the electrical responses of neuronal and non-neuronal cells of the retina recorded from corneal electrodes when the retina is stimulated by a full-field flash. It is based on six international standards developed by the International Society of Clinical Electrophysiological Vision (ISCEV) in 2008 (dark-adapted rod cell response, dark-adapted maximal mixed response, oscillatory potential, bright-adapted cone cell response, 30 Hz scintillation light response, and 10 or 30 cds/m2 high flash stimulus response for cataract patients). It is an excellent diagnostic aid for primary retinitis pigmentosa, congenital stationary night blindness, retinopathy, and macular degeneration.
