Roland Consult - Electrophysiology and Imaging

Infrared imaging cSLO

The combination cSLO + ERG/VEP is a worldwide unique technology.It allows simultaneous infrared laser monitoring during electrophysiological diagnostic. With the built-in stimulator, the high resolution DLP projector, it is possible to stimulate a large number of retinal locations and extract their responses. The final result is a function map superimposed onto the fundus cSLO image. Regionally confined areas of dysfunction can be detected.

The Roland Consult Fundus EyeTracker (RCFET) software helps to detect all eye movement artefacts during the test. The various electrophysiological functions are:

- multifocal ERG,
- focal flash ERG, focal pattern ERG,
- Pattern VEP,
- focal Pattern VEP and focal Flash VEP.

This device can also be upgraded with the classical electrophysiological stimulators and programs.

Module Angiography - The Angiography Module runs with a blue laser source (488 nm). It generates higher quality fundus images in comparison to alternative white light illumination photo systems and since no flashes are involved, the system is more patient friendly.

At the beginning of an injection the laser source automatically switch to Angiography mode and a video will be recorded with an exact timestamp on every image. This helps the user to concentrate more on the patient during the examination and review the angiography images later. The advantage of the laser system is also the high speed of image acquisition. Instead of watching static images from early, mid or late phase it is easy to observe the dye in the
vessels to localize narrowings and partial blockades.

Is a protein composed of 238 amino acid residues (26.9 kDa) that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range.
