Relationship between structural and functional changes in glaucomatous eyes: a multifocal electroretinogram study [PDF]

BMC Ophthalmology, 2021
Background The nasal to temporal amplitudes ratio (N/T) of multifocal electroretinography (mfERG) scans measured within 5° of the macula can be used to detect glaucomatous change.

A simplification of intricate multifocal electroretinogram understanding: A mini-review

Oman Journal of Ophthalmology
Variation of multifocal electroretinogram (mfERG) data presentation in existing scientific publications is a challenge for eye care practitioners to apply the scientific information for evidence-based practice in patient management. This review offers an

Applications of the multifocal electroretinogram in the detection of glaucoma [PDF]

Australasian journal of optometry, The, 2011
Glaucoma is one of the most important eye diseases resulting in blindness worldwide. It affects the inner retina and is without signs and symptoms in the early stages, making early detection of glaucoma important for eye care professionals. Electroretinography (ERG) is an objective technique used to measure retinal electrical responses, which directly ...

Slow flash multifocal electroretinogram in myopia

Vision Research, 2006
The purpose of this study was to investigate the characteristics of retinal function in myopes using a modified multifocal electroretinogram (mfERG) protocol, the slow flash (sf-mfERG) paradigm, which is thought to primarily reflect responses of ON- and OFF-bipolar cells and emphasize the late response components.Twenty-eight subjects (10 emmetropes ...
