A Visual Electrophysiology System is an advanced diagnostic platform designed to measure the electrical responses of the retina, optic nerve, and visual pathways. Using internationally standardized tests, the system evaluates functional vision beyond what conventional imaging (OCT, Fundus) can reveal. It is essential for diagnosing retinal disorders, macular diseases, optic nerve dysfunction, inherited retinal dystrophies, and neuro-ophthalmic conditions.
Modern electrophysiology systems combine ERG, PERG, VEP, mfERG, EOG, and various other test protocols in one integrated device. They use precise light stimulation, sensitive electrodes, and high-resolution recording amplifiers to generate accurate and reproducible visual pathway signals.
🔹 Key Diagnostic Capabilities
1️⃣ Electroretinography (ERG)
Evaluates global retinal function, including rods & cones.
Useful for:
Retinitis pigmentosa
Cone dystrophy
Diabetic retinopathy
Drug toxicity screening
2️⃣ Pattern ERG (PERG)
Assesses macular & ganglion cell function.
Useful for:
Early glaucoma detection
Macular dysfunction
3️⃣ Visual Evoked Potential (VEP)
Measures electrical activity from the optic nerve to the visual cortex.
Useful for:
Optic neuritis
MS-related optic nerve disorders
Amblyopia
4️⃣ Multifocal ERG (mfERG)
Provides topographic mapping of retinal function.
Useful for:
Macular degeneration
Central retina dysfunction
Toxic maculopathies
5️⃣ Electrooculogram (EOG)
Evaluates retinal pigment epithelium (RPE) function.
Useful for:
Best disease
Genetic retinal disorders
