Electrophysiology Of Eye | ERG | EOG | VEP

Описание: 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)
