DEVICE AND METHODS FOR MONITORING PROGRESSION OF LOSS OF VISUAL FIELD OF USER Russian patent published in 2020 - IPC A61B3/24 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment. Method for determining probability of presence or excess of preset speed or risk of progression of loss of vision field (VFP) in user includes stage (S100) of installation, including placing permanently worn sensor on eye or its implantation into eye of user. Measurement step (S101) involves measuring biomechanical properties of the eye (OBP) by means of a constantly worn sensor placed on the eye or implanted therein. Measurement involves repeated reading of data at regular intervals. Recording step (S102) includes recording biomechanical properties of the user's eye in the form of at least one OBP time series chart in the recording means. At the processing step (S103), one or more OBP parameters are extracted from the recorded schedule of the OBP time series. At calculation step (S104), said one or more extracted OBP parameters are combined with additional user metadata, so that VFP is calculated based on its correlation with OBP parameters. At determination step (S105) determining whether progression of loss of field of vision is at a level of a predetermined threshold value VFP or exceeds it, or the probability that said progression of visual field loss is within a specific range. At prediction step (S106), the probability of developing glaucoma in a patient based on the determined VFP is predicted. Evaluation step (S107) serves to assess the relevance of a particular treatment method based on said prediction result. Disclosed is a system for predicting progression of loss of visual field in a user by performing a method.

EFFECT: technical result consists in reducing time costs of the study and providing individual and clinical use.
