The subnormal ERG can be used in young patients to establish the diagnosis of hereditary progressive forms of retinitis pigmentosa and to determine visual prognosis even when changes visible with the ophthalmoscope are minimal or absent. Different waveforms have been demonstrated in patients of comparable age with different genetic types. Defects must exist in the photoreceptors or pigmented epithelium or both to explain the reduced ERG a-wave amplitudes and reduced ERT amplitudes. Marked… CONTINUE READING
