1. A method of obtaining pressure within the eyeball of a subject, the method comprising the steps of:
- (a) applying a constant known first reference pressure to a first location on the eyelid of the subject, wherein applying the constant known reference pressure to the first location on the eyelid comprises pressing a first applanation disk to the first location on the eyelid;
(b) applying at least a second pressure to an at least second location on the eyelid of the subject, applying the second pressure to the second location on the eyelid comprises pressing a second applanation disk to the second location on the eyelid;
(c) increasing the second pressure until a slight increase in the pressure is detected at the first location beyond the constant known reference pressure; and
(d) noting the second pressure being applied at the time the increase in the pressure is detected at the first location, the noted second pressure being an indication of the pressure within the eyeball.
