ABSTRACT:
This invention detects blood flow disorders by comparing the core body temperature, defined by a tympanic membrane measurement, to temperature measurements at various locations within the eye. The differential between the temperature measurement of the core body and that of selected site locations can yield an accurate indication of blood flow disorder within the eye. Areas at the back of the eye can be scanned at selected sites to obtain a temperature measurement profile, and again these temperatures will provide a difference when compared to the core body temperature and that can indicate abnormal blood flow. The use of additional instrumentation via computer technology or photography can be employed to map the fundus area of the eye and produce hard copies of results. The same principle can be utilized to determine abnormal blood flow patterns at subsurface skin locations caused by infections, disease, peripheral circulation, soft tissue intimation due to sprains, arthritis tendinitis, etc., vasodilation, and exposure to external environment.
