  • During the study, electroretinography was performed to measure the electrical signals from the retina.

Examples

  • The animals were sacrificed at the end of light exposure, except for 32 animals (8 from each exposure group) that were exposed to light for 28 days and then returned to a dark environment for 14 days of recovery (28+14 group) to allow for possible removal of necrotic photoreceptor cell debris. Electroretinography (ERG).

Surface Forms

electroretinography singular
electroretinographies plural

Morphology

electroretinography = retinography (semi-transparent) = electro + retin + graphy

The form clearly points to an electrical type of retinography, but the term is specialized medical vocabulary and not fully transparent to an average learner.

Etymology

Electroretinography is made of electro- meaning 'electricity', retina meaning 'the back part of the eye', and -graphy meaning 'writing or recording', like in photograph. So, electroretinography is a test that records the retina's electrical response to light.
