A device and method for comparing and correlating two or more disparate types of test data allows a doctor or technician to easily diagnose a condition or defect. A device or method embodying the invention can be used for diagnosing vision disorders by correlating visual sensitivity or acuity data to images or data corresponding to biological structures responsible for vision. Such a method allows a doctor to easily identify defects or conditions of a biological structure that causes a loss of vision. For instance, perimetry data which is indicative of visual sensitivity may be superimposed onto a fundus image of an eye to create a combined presentation of the data. In the combined presentation, the perimetry data overlies corresponding physical structures shown in the fundus image that give rise to the indicated optical sensitivities. The biological structure data may include an image of an eye, or an image of an optic nerve or a portion a brain responsible for processing optical data. The optical sensitivity data can be in the form of numerals indicative of optical sensitivity, isopter lines, or other types of patterns or symbols indicative of optical sensitivity. In one embodiment of the invention, optical sensitivity data and biological structure data may be stored in multiple data layers, and the data layers can be compared to one another to identify pattern matches between data layers. Similar methods can be used to compare and correlate any two or more disparate types of test data. |
