Abstract

An apparatus that measures images of at least a portion of an eye and records data sets indicative of a neurological condition. A method of the invention employs a plurality of images, or a plurality of data sets, or at least one image and at least one data set to provide an interpretive result based on the interrelation of the images and data sets, such as by superposition. The apparatus and method thereby provide guidance as to the presence of a medical condition in a patient. The apparatus includes modules that observe images and/or data sets, that analyze the information, and that superpose the information. Modules are provided to store information, to provide data output, to provide reports, and to display information, including superposed images and data. Modules can be provided in hardware, in software, in firmware, or in combinations thereof.

Claims

1. Apparatus for performing multiple procedures involving the retina of the eye, said apparatus comprising:

at least one imager for imaging at least a portion of an eye of a patient, said at least one imager configured to provide image data comprising at least two data types selected from the group consisting of data from ophthalmic images using confocal microscopy data, retinal polarimetry data, optical coherence tomography data, thermal image data, spectroscopic image data, refractometry data, and visible image data; and

a data analysis module that interrelates data from said at least two data types to provide an interpretive result that is indicative of a presence of an abnormality that appears to involve a retinal portion of the eye, and where said abnormality could actually involve, at least in part, an abnormality of the brain.

2. Apparatus as recited in claim 1, further comprising a display module that provides a display of interrelated data to a user.

3. Apparatus as recited in claim 1, further comprising a data output module that reports interrelated data from said at least two data types.

4. Apparatus as recited in claim 1, further comprising a report module that reports said interpretive result.

5. Apparatus as recited in claim 1, further comprising a single output module that reports interrelated data from said at least two data types and said interpretive result.

6. Apparatus as recited in claim 1, further comprising a superposition module for superimposing data obtained from at least two images.

7. Apparatus as recited in claim 6, further comprising a display for displaying superimposed data obtained from at least two images.

8. Apparatus as recited in claim 7, wherein said superimposed data obtained from at least two images comprises data obtained from at least two different data types selected from the group consisting of data from ophthalmic images using confocal microscopy data, retinal polarimetry data, optical coherence tomography data, thermal image data, spectroscopic image data, refractometry data, and visible image data.

9. Apparatus as recited in claim 1, further comprising a memory for storing image data.

10. Apparatus as recited in claim 9, wherein said memory for storing image data is configured to store and to selectively retrieve data from at least one image for determining changes induced in response to an applied stress.

11. Apparatus as recited in claim 10, where said applied stress is selected from the group consisting of intra ocular pressure variation, blood pressure variation, oxygen concentration variation, exercise, flashing light, drug administration, administration of insulin, and administration of glucose.

12. Apparatus as recited in claim 9, wherein said memory for storing image data is configured to archivally store image data.

13. Apparatus as recited in claim 1, wherein said data analysis module is configured to automatically determine a presence of an abnormality.

14. A method of treating a patient, comprising the steps of:

performing an examination of a patient using the apparatus of claim 1; and

treating said patient based at least in part on a result obtained from said examination.

15. The apparatus of claim 1 where said at least two data types include a first data type and a second data type, and where said first data type is optical coherence tomography data and where a second data type is visible image data and where an interpretive result indicates a presence of glaucoma or Alzheimer'"'"'s disease based upon said two data types.
