1. A method to detect relative inter-ocular pressure where:

  • a first sensor is directed at the tympanic membrane within one ear of a patient, and where said first sensor generates a first signal proportional to a core temperature of said patient; and

    where a first signal processing means converts said first signal into a core output signal, and where a second detector is directed at the macula of one eye of said patient by a directing means; and

    where said second sensor generates a second signal proportional to the temperature of said patient'"'"'s macula, and where a second signal processing means converts said second signal into a macula output signal, and where said core output signal and said macula output signal are compared by a primary comparing means, and where an output from said means is further compared with a preset value by a secondary comparison means, and where when the output exceeds preset values an alarm processing means provides audible, visible, tactile, electronic, or printed warning indicators.
