Abstract
The electroretinogram (ERG) is routinely recorded through a pair of electrodes; an active electrode on the cornea and a reference electrode on tissue bio-electrically near the sciera (forehead, chin, orbital margin…). Based on this recording system, a normal pattern of clinical ERGs has been established (Standardization Committees of ISCERG, 1962). However, the horizontal distribution of the receptor cells in the retina is not uniform, and the retina is attached to the posterior wall of the eyeball. The ‘normal’ pattern can be said to be temporarily established in this situational relationship between the electrodes and the eyeball (Noonan, Wilkus, Chatrian & Lettich, 1973).
