General introduction to RetinaLyze
The RetinaLyze® system combines the speed and efficiency of Artificial Intelligence with the guidance and supervision of telemedicine to dramatically lower the cost of eye screening and makes it possible to offer treatment to patients around the world at manageable costs.
The RetinaLyze® system enables retail eye care professionals such, as optometrists, to perform safe and easy eye screenings, thereby increasing the availability of eye-screenings for the general public.
As an optometrist, you can offer RetinaLyze screenings to your customers. Whether you plan to offer the screenings as an independent product or as an add-on to your standard eye exams, the availability of RetinaLyze screenings will enhance the professional brand of your store(s) and help you get a closer and more personal relationship with your customers.
Take a fundus photo/OCT-scan, send it to our service and receive results instantly.

Ensuring reliable results
To ensure reliable results of manual or automated assessment, it is highly important to only use good quality fundus images for the analysis. Be sure that you are familiar with the guidelines for image quality before using the system.
Ask if the customer has been treated for retinal illnesses before the eye exam.
If yes, do capture the image/scan, but do not comment on the state of the retina. Fundus laser treatment/scarring will cause false positives and the patient is most likely actively monitored by their GP/Ophthalmologist already.
If in doubt, always use the eye-specialist backup.
Ask if the customer is aware of any lifestyle/eye diseases already (such as diabetes, DR, AMD, Glaucoma, Cataract)
Only screen customers above 45 years of age for signs of AMD (to avoid false positives from reflections).
Only screen customers above 14 years of age for signs of DR (to avoid too many reflections in the macula/foveola area).
Only screen customers above 40 years of age for signs of Glaucoma (since the risk is especially elevated above 40 years of age).
Always check the image for reflections/shadows in the macula area as well as optic nerve head to avoid false positives and negatives.
If you don’t know if a spot is an artefact or an alteration, check the lens for dust/fat from the nose or other dirt and take a new image.
If the spot is in the same position with regards to the image, it’s probably an artefact.
If the spot is in the same position with regards to the macula and optic nerve head, it’s probably an alteration.
Generally, If in doubt, always use the eye-specialist backup.
How to analyze a retinal photo or OCT scan
Automatic upload/export of images/scans from your camera/OCT-device/software
Capture a fundus image or OCT-scan and export the image to RetinaLyze using the device or device software.
How to manually upload a photo/scan to RetinaLyze
If you do not have a fundus camera/OCT-device integration, you can upload the image to the system by using the formula on the right side.
Choose Fundus Image or OCT scan
Start by selecting "Browse..." and locating and selecting the image/scan on your computer.
Next, input the ID and name of the patient/client
Finally, click "Upload photo".
Running the analysis
When the image/scan has been uploaded you can see it in the list called "Not yet analyzed photos". From this list you can run the analysis by clicking on either "Run DR analysis", "Run AMD analysis", "Run Glaucoma analysis" or "Run OCT Analysis".
If you want to run multiple analyses simultaneously, you can do that by clicking clicking successively.
Finding the result of the analysis/analyses
When the image has been analyzed it will be moved from "Not analyzed photos" to "Analyzed images". In the "Analyzed photos" list you can see the result of the analysis. If your account is setup to use separate pages for Not analyzed and Analyzed photos, go to the Results-page to see the result/Analyzed photos.
Seeing an overlay and manipulating the image
If you wish to see the analyzed retinal picture you can click the ID no. or the picture. Here you will be able to see a bigger image, and be able to zoom in and out.
If RetinaLyze has found alterations, it will mark it with either black markings (signs of DR) or teal markings (signs of AMD). These markings can be removed by pressing either "Toggle DR overlay" or "Toggle AMD overlay". The Glaucoma overlay will show you the measured level of hemoglobin in the optic nerve head and can be toggled using the button "Toggle Glaucoma overlay".
For OCT scans, click on the scan or ID to see the detailed scan results. Individual b-scans will be marked in their respective result colors. Use the scroll-wheel on your mouse or the arrows on the screen to navigate the OCT-scan.
Understanding the results of the automated analysis
The result of the automated analysis is displayed in two parts.
One is a color-representation of the severity of the changes found (see image below), the other is an overlay marking the changes found.
Please read the following articles for an in-depth explanation of the results of the automated analysis:
Understand the results of the Age-related Macula Degeneration screening
Understand the results of the Diabetic Retinopathy screening
Understand the results of the Glaucoma screening
Understand the results of the OCT screening
Using the eye-specialist backup/tele-medicine service
The eye-specialist backup/tele-medicine service can be used to receive a manual assessment of a fundus images (and symptom data). It should especially be used to assess what the required next step is, if the result of the automated analysis indicates changes, if the symptoms of the patient require it or if the operator is in doubt.
Communicating the results to the patient/client
Communicating the results of the automated and/or manual assessment of a fundus image, as well as the recommended next steps, can be daunting task for some. To make it easier for you, we have made some guidelines and examples for communication with the patient/client below:
