“…It has been shown that for example in retinal detachment the amplitude of the b-wave is related to the area of undetached retina (Rendahl, 1957). With these facts in mind it seems reasonable to consider the use of ERG as a tool for measuring the extent of retinal destruction produced by photocoagulation.…”

Two groups of 10 diabetics were photocoagulated in different ways. In one group the treatment was started in the central area. The other group was initially coagulated in the periphery. ERGs were recorded before, between, and after the separate coagulation sessions. It was found that the ERG was reduced more than expected on the basis of the coagulated area. The fact that the central treatment reduced the ERG more than the peripheral treatment of the equal area indicates that it is the number of destroyed neural elements that is significant. The a-wave was reduced more than the b-wave. This may be explained by the fact that the coagulation lesion is maximal close to the receptor layer.

“…The size of the b-wave in the ERG is thought to be reduced in proportion to the area of the detachment, and the ERG is extinguished altogether if the retina dies (Rendahl, 1957). Electrodiagnostic tests are of importance when a detachment is suspected and the fundus cannot be viewed directly due to the presence of cataract or corneal opacities.…”

(Jacobson, 1961). Basis of the Electro-OculogramThe EOG is concerned with the slower changes in the standing potential of the eye rather than the rapid activity of the retinal neurones which produces the ERG. This standing potential can be measured using the "eye movement technique" in which electrodes are placed on either side of the eye and the eye moved from side to side. The potential difference induced between the two electrodes is then proportional to the standing potential on the eye and is recorded.In the clinical test, there is an initial drop in the standing potential during a period of dark adaption, followed by an increase in potential occuring over several minutes when the eye is subsequently exposed to light. This is the basis of the EOG (Arden, Barrada and Kelsey, 1962

“…Rendahl 285 studied with the electroretinogram 277 eyes with retinal detachment, finding a low b potential in the areas of detachment and also a lower than normal b potential in the opposite eye, even when no detachment was present. Brockhurst and associates283 discussed brief¬ ly the diagnosis, treatment, and prognosis of retinal detachment.…”
