Abstract

An apparatus that can measure images of at least a portion of an eye and record data sets indicative of a neurological condition. A method interrelates an image and a data set to provide an interpretive result. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus and method can be used in an iterative measurement process, in which the apparatus attempts to discern normal health from a state of health that is not normal health. If the interpretive result is consistent with normal health, the process terminates, information is recorded, and an optional report is given. If the interpretive result is not consistent with normal health, the apparatus and method attempts to distinguish which condition is consistent with the data and images used, and can iterate with additional measurements and information to attempt to provide a useful interpretive result.

Dependent claims

An apparatus for obtaining an interpretive result relating to a condition of a person, comprising:

at least one data collection apparatus for collecting from an eye of a person a data set indicative of a neurological disorder;
an analysis module comprising a programmable processor and computer software recorded on a computer-readable medium, said computer software when operating performing the steps of:
attempting to obtain from said one or more data sets an interpretive result relating to said condition of said person;
(a) in the event that said attempt to obtain an interpretive result relating to said condition of said person provides a result representing a state of normal health, recording said result and terminating said analysis;
(b) in the event that said attempt to obtain an interpretive result relating to said condition of said person provides a result representing a state of health that is not normal health, attempting to distinguish a condition represented by said state of health that is not normal health;
(b)(1) in the event that said attempt to distinguish said condition represented by said state of health that is not normal health is successful, reporting an interpretive result of said condition and terminating said analysis.
