Abstract[English]
An automated system for assessing a subjective severity of a patient-perceived floater in an eye of a patient includes a display screen, a patient-operated feedback device, and a floater assessment system (FAS). The FAS is configured to present a visual target on the display screen at a primary fixation point, and possibly at multiple secondary fixation points arranged radially around the primary fixation point. The FAS also receives feedback signals from the patient-operated feedback device in response to an activation thereof by the patient. The feedback signals are indicative of a location and possible size of the patient-perceived floater in the patient's field of vision. Additionally, the FAS calculates a numeric floater severity score using the feedback signals that quantifies the subjective severity of the floater(s).[French]
Est divulgué un système automatisé pour évaluer la gravité subjective d'un corps flottant perçu par un patient dans son œil, ce système comprenant un écran d'affichage, un dispositif de rétroaction actionné par patient et un système d'évaluation de corps flottants (FAS). Le FAS est conçu pour présenter une cible visuelle sur l'écran d'affichage au niveau d'un point de fixation primaire, et éventuellement au niveau de points de fixation secondaires multiples disposés radialement autour du point de fixation primaire. Le FAS reçoit également des signaux de rétroaction provenant du dispositif de rétroaction actionné par le patient, en réponse à son activation par le patient. Les signaux de rétroaction indiquent l'emplacement et la taille possible du corps flottant perçu par le patient dans son champ de vision. De plus, le FAS calcule un score numérique de gravité de corps flottants au moyen des signaux de rétroaction qui quantifient la gravité subjective du ou des corps flottant(s).
