SCREENING TESTS
CE agreed Medical Device, our solution, in its current versions, detects:
Diabetic Retinopathy and Diabetic Macular Edema; Age related Macular Degeneration and Age related Maculopathy; and Glaucoma
Diabetic Retinopathy (DR)
Diabetic Retinopathy and Diabetic Macular Edema together affect 20 to 50% of diabetics, for a total of nearly 150 million people worldwide.
SCREENING TESTS
CE agreed Medical Device, our solution, in its current versions, detects:
Diabetic Retinopathy and Diabetic Macular Edema; Age related Macular Degeneration and Age related Maculopathy; and Glaucoma
Glaucoma
Glaucoma affects about 80 million persons worldwide, and is the first cause of cecity in people over 60.
Age-Related Macular Degeneration (AMD)
Age related Macular Degeneration affects 200 million persons worldwide. Its early form is Age related Maculopathy.
Fundus photography quality check
- OphtAI checks in real time for submitted photos’ quality to verify it can be interpreted.
- Hence, the users know while screened persons are still present and available if they have to capture new images.
- This function allows using any fundus camera on the market, as long as its photos’ quality is sufficient.
Lesion mapping
- Our innovative technology, designed by our scientists, allows lesion mapping.
- This is the so-called heatmaps.
- They display the importance of each pixel in OphtAI’s decision.
- This is graphically represented as a proportionally intense luminosity.
Glaucoma Example – Slide to discover the “gradual borders” type heatmap
Performances
Diabetic Retinopathy | Glaucoma | AMD | |
Sensibility | 99% | 96.5% | 92.5% |
Specificity | 87% | 95.4% | 87% |
Response time | <3s | <3s | <3s |
Classification and Proportion of Similar Cases
- Depending on the proportion of images receiving a given score for each ground truth (usually, healthy or not for a given disease) on a database whose cases are balanced as a function of the disease’s prevalence ratio, we process the confidence level for the image score.
- A confidence level equates Positive predictive value for a positive diagnosis and a Negative Predictive Value for a negative diagnosis.
- So, if the patient is to be refered to an ophthalmologist (CNN output score >= threshold, confidence matches the probability for the patient actually being affected by the disease; this probability is low close to the threshold and reaches 100% when the score increases.
Grading
- OphtAI is able to grade DR’s severity stage
>>This function is very important as it allows knowing the appropriate course of action and the emergency level for the patient to meet an ophthalmologist.
PDF Report
- Our report is a Medical Device certified PDF allowing for diagnosis,
- available from any internet browser without external application,
- it is customizable and allows on demand anonymization, per disease results and confidence levels integration, and lesion mapping and importance integration.
100% cloud, 100% autonomous, easy to use and immediate.
Notice
A major disorder of the transparent media, such as cataract, does not allow reliable analysis of the retina by retinophotography: in this case, use of the device should be contraindicated.
