Computer-Based 3D Visual Field Test System And Analysis
Computer-Based 3D Visual Field Test System And Analysis
US Patent:
6578966, Jun 17, 2003
Filed:
Mar 27, 2001
Appl. No.:
09/820283
Inventors:
Wolfgang Fink - Pasadena CA
Alfredo A. Sadun - San Marino CA
Alfredo A. Sadun - San Marino CA
Assignee:
California Institute of Technology - Pasadena CA
International Classification:
A61B 302
US Classification:
351239
Abstract:
A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern is displayed to the patient on an electronic display device and the patients responses to the visual field test pattern are recorded. A visual field representation is generated from the patients responses. The visual field representation is then used as an input into a variety of diagnostic processes. In one embodiment of the invention, a series of visual test patterns of varying contrast are presented to a patient in order to construct a three-dimensional visual field representation wherein contrast sensitivity is plotted against a Z-axis.

US Patent:
6769770, Aug 3, 2004
Filed:

Assignee:
California Institute of Technology - Pasadena CA
International Classification:
A61B 302
US Classification:
351239
Abstract:
A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern including a peripheral fixation point is displayed to the patient on an electronic display device and the patients responses to the visual field test pattern are recorded. A visual field representation is generated from the patients responses. The visual field representation is then used as an input into a variety of diagnostic processes. In one embodiment of the invention, a series of visual test patterns of varying contrast levels or colors are presented to a patient in order to construct a three-dimensional visual field representation wherein contrast sensitivity is plotted as the Z-axis.
Method And System For Detecting, Characterizing And Monitoring Optic Nerve Diseases
Method And System For Detecting, Characterizing And Monitoring Optic Nerve Diseases
US Patent:
4826308, May 2, 1989
Filed:
Dec 31, 1985
Appl. No.:
6/815216
Inventors:
Alfredo A. Sadun - San Marino CA
Assignee:
University of Southern California - Los Angeles CA
International Classification:
A61B 302, G02C 712
US Classification:
351 49
Abstract:
A method and system are provided for detecting, characterizing and monitoring eye diseases and, particularly, optic nerve diseases, by determining the difference in relative brightness sensed by the two eyes. The method utilizes eyeglasses having a pair of cross-polarizing lenses selectively adjustable for blocking or admitting light into each eye. The patient observes an illuminated test object while looking through the eyeglasses at maximum luminance. By adjusting the relative polarization of the lenses for the eye in which the test object appears the brightest, while occluding the other eye, the amount of brightness sensed by that eye can be compared to the other eye. If there is a disparity in brightness-sense between the eyes within certain pre-established ranges, the nature of the eye disease can be detected and specifically characterized, and its progression or resolution can be monitored.

US Patent:
4818091, Apr 4, 1989

Appl. No.:
6/815368

Assignee:
University of Southern California - Los Angeles CA
International Classification:
G02C 712, A61B 307
US Classification:
351 49
Abstract:
A method and system are provided for detecting and monitoring the treatment of eye disease by determining the presence of visual field defects. The method utilizes eyeglasses having a pair of cross-polarizing lenses selectively adjustable for varying the amount of luminance of an Amsler grid as observed by the patient through the eyeglasses. By adjusting the relative polarization of the lenses separately for each eye until the patient is barely able to see the Amsler grid, the sensitivity of the patient's eyes to the presence of scotomas is greatly increased. By having patients record the presence of scotomas while observing the Amsler grid through the eyeglasses, it is possible to screen patients for visual loss associated with various eye diseases, such as atrophic SMD. Recording the existence of scotomas on a periodic basis enables an ophthalmologist to determine whether atrophic SMD may be advancing to hemorrhagic SMD requiring treatment to prevent permanent loss of central vision.
