Electroretinographs

Definition : Graphic recorders of the changes in electrical potential on or near the surface of the cornea to a reference distal point on the body, following stimulation of the retina by light (i.e., flashes of white light). These recorders include a primary electrode (typically gold, platinum, or silver), a reference electrode located almost anywhere in the body (e.g., cheek, earlobe), and an amplifier that boosts the bioelectrical potential. Some recorders are compatible with personal computers for waveform storage and analysis. Electroretinographs are used in the diagnosis of retinal degeneration, night blindness, and circulatory disturbances of the retina.

Nihon Kohden America Inc

Many factors affecting health care today have created the "perfect storm." Rising costs, reimbursement issues, a nationwide shortage of nurses and, most significantly, the need for hospitals to improve quality of care all impact patient care. But these challenges can also be seen as an opportunity to return to the fundamentals of people caring for other people—using technology as the enabler of change.
