Electrophysiology Of Eye | ERG | EOG | VEP

Electrophysiology of the Eye | ERG | EOG | VEP | Complete Overview Electrophysiology helps us understand the functional health of the retina and visual pathway — beyond what routine eye exams can detect. In this video, we break down the three major tests used in clinical ophthalmology & optometry: ✅ What You’ll Learn 🔹 Electroretinography (ERG) – evaluates retinal function (photoreceptors, bipolar & Muller cells) 🔹 Electrooculography (EOG) – assesses RPE/photoreceptor interface and standing potential of the eye 🔹 Visual Evoked Potential (VEP) – measures the functional integrity of the optic nerve & visual cortex 🧠 Why These Tests Are Important ✔ Detect subclinical retinal disease ✔ Essential in inherited retinal dystrophies ✔ Evaluates macular vs peripheral retinal function ✔ Helps differentiate retina vs optic nerve pathology ✔ Useful in medico-legal / disability assessment 📍 Clinical Indications Covered Retinitis pigmentosa & inherited retinal dystrophies Central serous chorioretinopathy (CSCR) Drug toxicity (e.g., hydroxychloroquine) Optic neuropathies & demyelinating disease Amblyopia & functional vision loss (VEP utility) #Electrophysiology #ERG #EOG #VEP #RetinaFunction #VisualPathway #Ophthalmology #Optometry #EyeTesting #VisionScience #Retina #OpticNerve #ClinicalOphthalmology #MedicalEducation #NeuroOphthalmology #InheritedRetinalDiseases #RetinitisPigmentosa #VisualEvokedPotential #Electroretinography #Electrooculography #EyeExam
