What changed

The USPTO published a patent application for a visual field testing method and device (Application US20260083318A1, published March 26, 2026). The invention covers display-based visual field testing where a central stimulus point is presented for a first duration, followed by central and peripheral targets displayed according to a preset strategy. Subject responses to trigger operations determine both response results and the target position area for subsequent rounds of testing. The application identifies six inventors and classifies under CPC codes A61B 3/024, A61B 3/0058, and A61B 3/0091.\n\nMedical device manufacturers developing visual field or perimetry testing equipment should review this patent to understand potential intellectual property considerations. Healthcare providers using such diagnostic devices should be aware that new testing technologies may enter the market. No compliance deadlines or penalties are associated with this patent publication as it does not create regulatory obligations.

Abstract

A method and a device for visual field testing are provided. The method is applied to a piece of display equipment which includes a display for presenting a detection interface. Within a preset first duration, a central stimulus point is displayed on the detection interface. Within a preset second duration, a central target and a peripheral target are displayed on the detection interface based on a preset target display strategy. In response to a subject's first trigger operation on the detection interface, a first response result corresponding to the first trigger operation and a target position area of a next round of display of the peripheral target are determined. Further, a testing result of the subject is determined based on the first response results corresponding to a preset number of detections.
