OdySight® is a medical software intended for self-evaluation of the following visual parameters: near visual acuity and symptoms such as metamorphopsia and scotoma. The test results are transmitted to physician.


OdySight® doesn’t interpret the test results and it is not intended to diagnose but rather to help patients determine if they need to consult a physician for diagnosis and treatment.
Indications: OdySight® is indicated for adult patients aged 18 and over.

OdySight is a remote based medical monitoring system, which can be used by the patient remotely and can report results into a web dashboard at the clinical center, allowing the healthcare professional to identify those patients who need to come in for a visit and examination.

The app is prescribed to the patient by a healthcare professional.

It is intended for patients with eye disease that, from the point of view of the healthcare professional, would benefit from remote monitoring of visual parameters: near visual acuity or presence or progression of metamorphopsia and scotoma. It is to assist with the planning of follow up care between scheduled clinic visits.

OdySight is recommended for patients affected by eye disease requiring regular, close monitoring of vision, such as wet or dry forms of AMD at risk of neovascularization, diabetic retinopathy with or without macular edema, high myopia with risk of neovascularization and other similar, treatable causes of blindness.

OdySight doesn't interpret the test results and is not intended to diagnose. The diagnosis and patient treatment remain the responsibility of the physician.

OdySight does not replace regularly scheduled clinic visits to monitor eye diseases.

OdySight shall be prescribed to adult users who have:

a) Binocular vision equal to or better than 3/10 (0,5 logMAR; (20/63))

b) Access to a compatible smartphone and/or tablet

c) A valid email address and phone number to create an account

The competence to use the app and complete the test modules remotely, without the guidance of a healthcare professional

OdySight app is contra-indicated for:

• epileptic users
  
• users with a binocular visual acuity of less than 3/10 (0.5 logMAR; 20/63)
  
• users with both eyes with monocular visual acuity lower than 1/10

OdySight is a digital technology system composed of two different components: the OdySight app for users and OdySight dashboard for healthcare professional.

The OdySight app is divided into the following modules:

• the Near Visual Acuity (NVA) module allows the user to test their visual acuity; based on the ETDRS (Early Treatment for Diabetic Retinopathy Study);

• the Amsler Grid (AG) module evaluates metamorphosis and scotomas; based on the paper Amsler grid;
• the authentication module allows users to securely connect to the OdySight application;

• the menu module allows for navigation within the OdySight app;

• the game and DLC modules: related to the puzzles which are designed for the retention of the user.

The OdySight online dashboard

Intended for the healthcare professional who prescribes the OdySight app to users. The healthcare professional can then view the results from the medical tests performed by users.

NB: The game module is not considered as a part of OdySight as medical device.

OdySight app

The application consists two parts: visual tests (visual acuity, Amsler grid), and a game (puzzles). The visual tests are intended to collect test results similar to those usually obtained in a medical center using standard methods.

The visual acuity test assesses near vision, while the Amsler grid test assesses the evolution of scotomas (black spots) and / or metamorphosis (deformation).

OdySight Dashboard

The dashboard, intended for use by healthcare professionals, is a secure website for viewing the results of visual tests taken by their patients.

OdySight allows the remote monitoring of visual parameters.

OdySight is a tool intended to complement your standard medical monitoring.

It does not replace visits and examinations prescribed by your physician, which you should continue to attend.

If the results of your tests seem to indicate the need, OdySight will advise you to contact your referring healthcare professional. Their contact details are recorded and can be accessed from the application.

This clinical investigational plan was designed to evaluate visual acuity, an important component of any eye examination and used to establish and monitor a patient's ocular status. Visual acuity is the most used visual parameter to characterize and follow up chronic optical diseases.

The visual tests have been compared and evaluated during a clinical study to standard tests performed in medical centers. The clinical study demonstrated that the visual acuity tests and the Amsler grid of OdySight have a significant accordance to the tests carried out in medical centers (gold standards used - the EDTRS Sloan near visual and distance ETDRS charts and paper Amsler Grid).

NB: Visual acuity alerts will be validated as part of clinical trials.

The color of paint splatters appearing in vision tests (visual acuity) is of purely artistic interest and does not indicate a right or wrong answer.

Every day, OdySight tells you which test has to be done and on which eye. On average, a test takes 5 minutes to complete.

This test allows you to unlock the fun part of the application. These game sessions are designed to be relatively short and not tire your eyes.

Visual acuity test

Visual acuity is the ability to discern the thinnest possible character with maximum contrast. In the monitoring and diagnosis of ocular diseases, we carry out this measure eye by eye using optimal optical correction (corrective lenses).

The international standard for vision tests is the ETDRS. The test used in OdySight is directly inspired by this reference.

For reasons of international compatibility, OdySight uses the version of the ETDRS with the "Tumbling E", which is already used in certain sight tests:

Near visual acuity, as calculated in OdySight, is tested at a set distance of 40 cm, one eye at a time, with glasses for near vision.

IMPORTANT: If the results of your tests seem to require it, OdySight will advise you to contact your doctor. Please follow this advice.

Amsler grid test

The Amsler grid was created by Marc Amsler, a Swiss ophthalmologist, in 1945. It is a self-monitoring tool for maculopathies such as AMD and macula edema.

By staring at the center of the grid with one eye open at a set distance (around 40 cm), a person may see metamorphopsia (wavy lines) or scotoma (white, colored, or black patches) appear, which are symptoms of a change to an optical condition. In this case, monitoring by an ophthalmologist is required.

If, when taking the Amsler grid test on OdySight, you notice the appearance or deterioration of one of these anomalies, contact your doctor immediately.

Personal health data are made available to the physician on a dashboard. Such data including the results of the vision tests are hosted by a certified health data server in the European Union. The transmission of data by the server to the dashboard is secured and encrypted.

The Map

The map is the main menu in the application. It is from here that you can start a vision test, play the puzzle game, change your settings, or find information about OdySight.

To access it, click the Pause (II) button at the top of your screen. To return to the map, click on "Return to the map" at the bottom of the menu.

Menus

OdySight has three menus, accessible from the map:

You can start a test in two ways:

• When you open the application for the first time each day, a window will appear letting you know you need to take your daily test. You can click accept, then follow the instructions shown on the screen.

• When you click on the Visual test menu, a list of tests will appear. Click on a vision test and follow the instructions shown on the screen.

The visual acuity test is presented in the form of a short and interactive test in which the user must indicate the direction of the letter "E" by swiping their finger in the corresponding direction (top, bottom, right, or left).

The Amsler grid test is a digitalized version of the paper Amsler grid. By using their finger as a pencil, the user can draw any irregularities which they see appear.

The results are shown at the end of each vision test:

• The results for the visual acuity test are shown out of 10 (Monoyer scale). The Monoyer scale is a unit of measurement for visual acuity currently used by ophthalmologists. The results shown are for information purposes only.

• The results of the Amsler grid are presented in the form of an image.

⚠️ The color of paint splatters appearing in vision tests (visual acuity) is of purely artistic interest and does not indicate a right or wrong answer.

⚠️ The visual acuity test results may be different from those obtained during an appointment. OdySight measures near vision, nor far, as may be done during an appointment. In addition, OdySight may not use the same system of measurement as your ophthalmologist.

If variations above the threshold determined by the app are detected, an alert is triggered. You are advised to contact your clinic to discuss the possibility of setting up an appointment.

To take the different tests, the screen of your device must admit sufficient light. This is why the phone should be properly charged to avoid it going into "low battery" mode.

If the batter has less than 30% remaining, the application will not let the user start the tests, and if the battery is below 15%, the application will stop entirely; the phone much be recharged to continue.

For the best test performance, it is important that the device's screen is intact and free of any deep scratches or dents and is clean.

OdySight does not replace your healthcare facilities visit and tests prescribed by your healthcare professional as part of monitoring your vision. Continue follow your visits calendar.

OdySight does not provide an interpretation of test results, diagnose or treatment recommendations. It is not intended to provide a diagnosis. Diagnosis remains the responsibility of the physician.

All medical decisions must be made by a healthcare professional.

If you notice a change in your vision and you think there is a need, contact the healthcare professional who prescribed you OdySight. Their contact information is available in the app.

The application should be used only by the patient whom the application has been prescribed to ensure that the data being sent to the healthcare professional.

The test results may differ from those obtained during your medical appointment. They should be considered as relative values.

The OdySight alert system is not intended to have a direct impact or change the clinical care flow for patients suffering from a chronic ocular disease, but it is only intended to help healthcare professionals to improve patient follow-up. The specificity and sensitivity of the alert system for the evaluation of new and/or adverse events in chronic ocular disease has not yet been confirmed.

During your tests, do not force your sight. During visual acuity tests, a "I don't know" button will appear after a few seconds without touching the screen. If you click it, the size of the "E" will increase. This will not distort your results, feel free to use it.

Do NOT use this product to self-diagnose vision problems. Do NOT leave your smartphone or tablet within reach of children while performing your tests.
