| DESCRIPTION |
Retiport is a low-price PC-based, 2-4-8-channel system for
measuring bioelectrical signals generated both from the retina and
the optic nerve. The basic set comprises: computer device, operator
monitor, printer, keyboard, mouse, bioelectrical amplifier, electrodes
and checkerboard monitro. All electrical connections are easily to
install.
The recorded curves are displayed on a operator monitor. By settingmarkers
the system allows conputing latencies and amplitudes automatically.
Data may be printed out or transmitted by an interface to another
PC. The plain basic equipment already provides-in compliance with
the ISCEL (International Society for Clinical Electrophysiolgy and
Vision)-simple and rapid determination of VER, EOG, ERG and pattern
ERG without strain for the patient. |
