Abstract :
Conventional systems for electroretinography (ERG) use complex electronic circuit to get electrical corneal signals (ECS), they usually use dedicated data acquisition hardware to acquire the signal over the corneapsilas eye. In this paper we proposed a simple method to acquire the ECS using the computer sound card to put into the PC the ECS. We show the results of the signals acquired from the cornea through microphonepsilas port.
