[Electrophysiology and early glaucoma diagnosis]

Area of Science:

• Ophthalmology
• Neuroscience
• Medical Imaging

Background:

• Glaucoma causes irreversible vision loss and is challenging to diagnose early.
• Early detection of glaucomatous damage is crucial for preserving vision.

Purpose of the Study:

• To review the latest advancements in using visual electrophysiology for early glaucoma diagnosis.
• To highlight the role of specific electrophysiological techniques in assessing retinal ganglion cell function.

Main Methods:

• Overview of pattern electroretinogram (PERG).
• Review of photopic negative response (PhNR).
• Summary of multifocal electroretinogram (mfERG) applications.

Main Results:

• Pattern electroretinogram, photopic negative response, and multifocal electroretinogram provide key information for early glaucoma diagnosis.
• These techniques can detect early functional degeneration of retinal ganglion cells.

Conclusions:

• Visual electrophysiology is a valuable tool for objective and functional assessment in early glaucoma.
• These electrophysiological methods assist clinicians in diagnosing and managing glaucoma patients effectively.
