Utilizing the unique short corrected m sequence (Deutsches Patentamt Munchen Pat. Nr. 19649858/1998) to generate a stimulus (flash, pattern and color) via a high class specially selected 21 customs monitor (≥ 60 Hz frame time) on 30 dgr visual field, the state of the art RETIscan offers an objective patient test to quantify the retinal response.

The stimulated areas respond in accordance with the special algorithm and deliver an individual reproducible ERG signal for each segment (1 segment is 1 hexagon).
Each cycle comprises a complete short length m-sequence and takes as lettle as 30 seconds for up to 61 stimulus segments and less than one minute for 103 or 241 segments. The final raw data result is derived from a free selectable number of cycles by averaging. Artifacts are detected within a selectable range and are discarded automatically. A preset testrun sequence may be interrupted for any reason, continued or the current cycle discarded.

Additionally the RETIscan gives the opportunity to link it to different Rodenstock Scanning Laser Ophthalmoscope (SLO), red stimulus to give simultaniously a topographic and functionally electrophysiological result of the visually controlled retinal area.
Markers for a and b wave from the ERG graph are set automatically but may be placed manually for each ERG to check the recorded amplitude and latency.
The RETIscan incoroaes a high sensitive two channel amplifier with an outstanding signal to noise ratio.

The instrument is useful for monitoring the disease process of the local retina or cortex. It is now also possible to measure the VER on the visual cortex.

Upgradable with RETIport Soft-and Hardware (ERG, VER, EOG, Pattern ERG, ISCEV standard). All in one.

RETIscan P is a low price Retiscan with selected functions.
