Visual testing method and apparatus |
摘要 |
Method and apparatus for visual testing. In one embodiment, for perimetry testing, the method uses threshold light-stimulus values determined at multiple seed locations in a visual field to calculate expected stimulus threshold values at locations which are nearest-neighbors of the seed locations. The expected values at the nearest-neighbor locations are compared with subject responses at these locations, and the correspondence between the two is used to refine and guide line stimulus level presentations at the nearest-neighbor locations. The test is continued until a selected confidence level of response at nearest-neighbor locations is reached.
