OdySight is based on the frequency of tests performed by your patient during the last 31 days to notify visual acuity decreases. This application takes into account the following main parameters:
- Variability, i.e. the propensity of the patient to record more or less constant results. The algorithm thus adapts to the patient's profile: if a patient presents variable results, OdySight will not notice a decrease in Visual Acuity at each change that is considered as normal for this patient.
- Frequency, i.e. how regularly the patient takes tests. For patients who take tests frequently and regularly, the application will consider a larger number when looking for potential changes. Patients who take tests less often will have fewer tests in their analysis, minimizing the time intervals that are too large.
These two elements allow the system to determine a minimum acceptable threshold, above which no decrease in Visual Acuity will be noticed, avoiding the generation of unnecessary notifications in case of insignificant changes. Below this minimum threshold, a decrease in Visual Acuity is triggered. Especially for patients with variable VA, it is important to perform regular and frequent tests.
If a patient presents a decrease in Visual Acuity, no new decrease for the same eye can be triggered for at least 6 days, to account for the first decrease observed.
