## Abstract

Computer-implemented systems and methods link time-stamped OCT scan data of a patient's retina in a database to a biometric identifier for the patient. An appropriately trained artificial intelligence (AI) computer system determines whether the patient has an eye disease based on the differences between time-stamped OCT scan data for the patient from different time scans.

### Claim 10 (depends on 1)

The system of claim 1, wherein:
the local computer is configured not to transmit a name, a mailing address, a birthday, and a social security number for the patient to the back-end computer system; and
the back-end computer system is configured not to link the patient's name, mailing address, birthday and social security number to the biometric scan data for the patient.

### Claim 11 (depends on 1)

The system of claim 1, wherein the local computer system is configured to encrypt the time-stamped OCT scan data and the biometric scan data for the patient prior to transmitting the time-stamped OCT scan data and the biometric scan data for the patient to the back-end computer system.

### Claim 12
