US 6116736 AAbstract
1. A pupilometer comprising:a CMOS sensor for generating image data representative of a pupil of a patient; and deformation detection means coupled to said CMOS sensor for identifying one or more selected regions within an image of a perimeter of said pupil that exhibit a predetermined amount of regional distortion. 2. A pupilometer comprising:a microprocessor; a memory coupled to said microprocessor; an imaging device coupled to said microprocessor; a visible light source coupled to said microprocessor; an IR light source coupled to said microprocessor; and a display coupled to said microprocessor; said memory having stored therein a program for enabling said microprocessor to cause a plurality of visible light stimulus pulses to be generated by said visible light source, to cause said IR light source to generate IR light for illuminating a pupil, to enable said imaging device to acquire a plurality of images of said illuminated pupil, to process data sets representative of said images of said illuminated pupil to obtain information descriptive of a response of said pupil to said visible light stimulus pulses, and to cause said information to be depicted on said display; said information descriptive of a response of said pupil to said visible light stimulus pulses comprising information indicative of a degree of non-uniform deformation of a selected segment of a perimeter of said pupil. 3. A handheld pupilometer comprising:a housing having a display, microprocessor, memory, imaging device, visible light source and IR light source mounted therein; said microprocessor being electronically coupled to said display, said memory, said imaging device, said visible light source and said IR light source; and said memory having stored therein a program for enabling said microprocessor to cause at least one visible light stimulus pulse to be generated by said visible light source, to cause said IR light source to generate IR light for illuminating a pupil, to enable said imaging device to acquire a plurality of images of said illuminated pupil, and to process a plurality of data sets representative of said plurality of images of said illuminated pupil to obtain information descriptive of a response of said pupil to said at least one visible light stimulus pulse, and to cause said information to be depicted on said display; said information descriptive of a response of said pupil to said at least one visible light stimulus pulse comprising information indicative of a degree of deformation of a selected segment of a perimeter of said pupil. 4. The handheld pupilometer of claim 3, wherein said information descriptive of a response of said pupil to said at least one visible light stimulus pulse comprises information descriptive of a dynamic response of said selected segment of said perimeter of said pupil.
