Retina Computer-Aided Detection

AI Software for Analysis of AMD, DR & Glaucoma

RetCAD is a computer-aided detection system that detects abnormalities related to Age-related Macular Degeneration (AMD), Diabetic Retinopathy (DR) and Glaucoma.

Software to Detect AMD or DR

RetCAD is a class IIa CE-certified software product using Artificial Intelligence that analyses color fundus images for the presence of Age-related Macular Degeneration (AMD) and Diabetic Retinopathy (DR).

With today’s digital color fundus cameras, one or multiple images can be acquired from a patient within seconds and are presented on the operator’s computer screen. RetCAD will automatically start analysing any acquired color fundus image and provide the user with a score and heat map that indicate referable Age-related Macular Degeneration and/or Diabetic Retinopathy.

Instant Identification and Follow-up

Patients with signs of Age-related Macular Degeneration or Diabetic Retinopathy are instantly identified. These patients require follow-up by an eye-care specialist. Patients with no signs of Age-related Macular Degeneration or Diabetic Retinopathy do not require follow-up and are advised to have an eye examination again in one or two years.

The performance of RetCAD is at the same level as trained certified graders. This means reduced workload for eye-care specialists, which in return can spend more time on e.g. reading abnormal images.

How RetCAD works?

  • Automatic transfer of fundus images to Thirona servers via a secured Internet connection. The image data is anonymized before transfer.
  • Processing/analysis on the Thirona servers with RetCAD AI. This takes approximately 1 minute.
  • Results of the RetCAD software are sent back to the user and imported to the client application. The results can be accessed and viewed directly from within the application or online via the Thirona web application.
