Title: Innovations by Stuart J McKinnon in Visual Field Perimetry
Introduction
Stuart J McKinnon is an accomplished inventor based in San Antonio, TX (US). He has made significant contributions to the field of visual field perimetry, holding 2 patents that focus on innovative methods for visual testing.
Latest Patents
One of his latest patents is titled "Method for establishing fixation in visual field perimetry." This invention provides a method for establishing fixation during computerized visual field perimetry. It requires the subject to fixate on a stationary target while moving a secondary target towards it. The stationary fixation target is designed to be easily identifiable, typically appearing as a small red circle on a monitor. The subject uses a computer mouse to interactively move the secondary target, and when the two targets overlap, a flashing visual test stimulus is displayed for a preset time.
Another notable patent is "Visual test using counter-phase chromatic and achromatic stimuli." This novel psychophysical visual test is based on the eye's response to alternating chromatic complementary colors or achromatic grays. It aims for the early detection of glaucoma and other diseases. The visual stimulus alternates between two complementary colors, such as blue and yellow, against a gray background. As saturation is reduced, individuals with glaucoma find it increasingly difficult to distinguish the visual stimulus, making this test beneficial for early detection.
