Abstract

In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data.

First claim

a processor configured to perform at least one ophthalmic functional test using the target display and perform movement tracking of at least one structural element of the eye; and
an output device configured to output on the output device a report based on an analysis of the optical coherence tomography scan,
wherein the at least one ophthalmic functional test comprises a central vison distortion test or a reading speed test.

2. The optical coherence tomography-based system of claim 1 , wherein the at least one ophthalmic functional test comprises the central vision distortion test.

3. The optical coherence tomography-based system of claim 1 , wherein the at least one ophthalmic functional test comprises the reading speed test.

4. An optical coherence tomography-based system comprising:
an optical coherence tomography device configured to obtain a first optical coherence tomography scan of a region of an eye of a user at a first time period and a second optical coherence tomography scan of the region of the eye of the user at a second time period; and
a processor configured to perform movement tracking of at least one structural element of the eye between the first and second optical coherence tomography scans, and the processor configured to perform at least one ophthalmic functional test based on the movement tracking,
wherein the optical coherence tomography device comprises at least one eye piece and a target display visible through the at least one eye piece, the target display configured to display fixation targets during performance of the at least one ophthalmic functional test, and
wherein the at least one ophthalmic functional test comprises a pupillometry test.

5. The optical coherence tomography-based system of claim 4 , wherein the at least one eye piece comprises first and second oculars, and wherein the first and second oculars are configured to receive a pair of eyes of the user.

6. The optical coherence tomography-based system of claim 4 , wherein the optical coherence tomography device includes at least one of an infrared-based imaging system or a scanning laser ophthalmoscope imaging system.

7. The optical coherence tomography-based system of claim 4 , wherein an output is transmitted electronically to a remote location other than a location of the optical coherence tomography-based system.

8. The optical coherence tomography-based system of claim 4 , further configured to output at least one of a risk assessment, a diagnosis, or a differential diagnosis based on at least a result of the at least one ophthalmic functional test.

9. The optical coherence tomography-based system of claim 4 , wherein the processor is further configured to compare a result of the at least one ophthalmic functional test with at least one of a reference value, a normative value, or a previously measured result of the at least one ophthalmic functional test.

10. The optical coherence tomography-based system of claim 4 , wherein the optical coherence tomography device is further configured to enable the user to self-administer the optical coherence tomography scan.

11. The optical coherence tomography-based system of claim 4 , further comprising an output device configured to generate an output on the output device based on the at least one ophthalmic functional test.
