Your doctor may also use a machine to measure your peripheral vision. The automatic perimetry machine is used to perform this test. You will be shown some light flashes in and around your field of vision. You will have access to a button that you will have to press as soon as you ...
Peripheral sensitivity was determined simultaneously for light flashes presented at different eccentricities along the horizontal meridian. In general, the results showed no losses in peripheral sensitivity or a "tunnel vision" effect under the experimental conditions employed. Three more experiments have ...
(Holladay & Simpson, 2017). Even if there were no complaints about dark shadows, these evaluations raise questions about vision characteristics in the far periphery. Some IOL patients have also been bothered by “positive dysphotopsia”, where they see bright arcs or flashes of light at night....
However, the majority of these studies have presented stimuli to central vision. The aim of the study presented here was to test the sensitivity of peripheral vision in ASD. This was achieved by asking participants to detect brief flashes of light presented between 30 and 85 degrees away from ...
VisionCutaneous stimulationAn analysis of evoked potentials recorded by gross electrodes in the curarized cat mesencephalic reticular formation by the presentation of light stimuli to the atropinized eye, electrical stimulation of a muscle nerve and skin, and acoustic clicks. A topographical distribution...
