In order to setup the Horus DEC200 for use with the glaucoma algorithm follow this guide.

Why use an alternate flash setting?

The RetinaLyze Glaucoma algorithm relies on the colours in the fundus photo to detect damage to the optic disc, which indicates signs of glaucoma.

In some cases, the camera needs to be calibrated to allow the full spectrum of colours to be present in the fundus photo. This can be achieved quickly on the Horus DEC200 by decreasing the flash using the brightness button on the fundus camera. The RetinaLyze web application will give you a warning, when you need to use the mode:

"The image is too saturated to perform the analysis, please capture a new photo with a lower flash setting."

How to use the alternate flash setting

1. Press '-' on the BRIGHTNESS button on the device until Brightness level 3 is reached

The optimal flash setting varies based on the patient's pupil size. Please try Brightness level 5 or 6, if the image is too dark/you are unable to capture images with Brightness level 3.

2. Capture the image

3. Remember to switch back to Brightness level 10, when you have captured the image for the RetinaLyze Glaucoma algorithm. This is accomplished by pressing '+' on the BRIGHTNESS button until Brightness level 10 is reached.
