[Multifocal visual electrophysiology in visual function evaluation]

Area of Science:

• Ophthalmology and Neuroscience
• Forensic Medicine

Context:

• Multifocal visual electrophysiology, encompassing multifocal electroretinography (mfERG) and multifocal visual evoked potential (mfVEP), offers objective assessment of retinal function and visual pathway integrity.
• Its advantages include short testing times and high sensitivity, leading to widespread clinical use in ophthalmology for diagnosing retinal diseases and glaucoma.

Purpose:

• To review the methodology of multifocal visual electrophysiology, including stimulation techniques, electrode placement, and data analysis.
• To discuss the application and value of mfERG and mfVEP in evaluating visual function, particularly in the context of ocular trauma within forensic medicine.

Summary:

• This article details the stimulation methods, electrode positioning, and analytical approaches for multifocal electroretinography (mfERG) and multifocal visual evoked potential (mfVEP).
• It highlights the objective evaluation of retina function and the retina-cortical conduction pathway by simultaneously recording responses from multiple retinal areas.

Impact:

• Multifocal visual electrophysiology provides a sensitive and objective tool for diagnosing various retinal conditions and glaucoma.
• Its application in forensic medicine offers a novel method for assessing visual function in cases of ocular trauma, expanding its clinical utility.
