Routine ERG recording with LED light stimulus.
An apparatus for ERG recording in clinical practice using light-emitting diodes as stimulation light is described and evaluated. By introducing special electronic devices, slow potentials (c-wave) can be recorded and there is no need for a shielded cage. The function of the set-up is trouble-free and the reproducibility is very satisfying.
