Example Sentences

Simply put, ERG consists of taking measurements of the electrical potentials generated by neurons and other cells in the retina from the surface of the cornea.

From Science Daily

Many ocular diseases cause abnormalities in a person's ERG signals, including glaucoma, retinitis pigmentosa, and diabetic retinopathy.

From Science Daily

Although many types of ERG measurement devices exist, few ERG electrodes can measure multiple localized ERG signals from different regions of the retina at the same time.

From Science Daily

Against this background, a research team led by Professor Takeo Miyake from the Graduate School of Information, Production and Systems at Waseda University, Japan, set out to develop a new type of soft ERG multi-electrode system to overcome these issues.

From Science Daily

The result of this innovative process is a flexible and highly transparent multi-electrode system for ERG measurements that is just as comfortable as commercial disposable contact lenses.
