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.

Optical coherence tomography-based ophthalmic testing methods, devices and systems

Apparatus and methods for eye tracking using an optical coherence tomography (OCT) device are disclosed. Such eye tracking may be performed by using information about the shape of the cornea and the corneal apex or using the iris/pupil border obtained using the OCT device.

Medical devices, systems, and methods for performing eye exams and eye tracking

A mask for performing an eye exam of a subject includes one or more optically transparent sections for transmitting an incident light beam therethrough and incident on the subject's eye. In some embodiments, the one or more optically transparent sections are coated with an anti-reflective coating configured to reduce reflection of the incident light beam by the one or more optically transparent sections. In some embodiments, the one or more optically transparent sections may have a portion thereof that is tilted with respect to the incident light beam when the mask is optically interfaced with the docking portion of an ophthalmic instrument, such that the incident light beam forms a finite angle of incidence with respect to the corresponding portion of the optically transparent sections.

Medical interfaces and other medical devices, systems, and methods for performing eye exams

In accordance with one aspect of the present invention, an optical coherence tomography instrument comprises an eyepiece for receiving at least one eye of a user is provided; a light source that outputs light that is directed through the eyepiece into the user's eye; an interferometer configured to produce optical interference using light reflected from the user's eye; an optical detector disposed so as to detect said optical interference; and electronics coupled to the detector. The electronics can be configured to perform a risk assessment analysis based on optical coherence tomography measurements obtained using the interferometer. An output device can be electrically coupled to the electronics, and may be configured to output the risk assessment to the user through the output device. The optical coherence tomography instrument can be self-administered, and the eyepiece can be a monocular system or a binocular system.

An inflatable mask with two ocular cavities can seal against a user's face by forming an air-tight seal around the periphery of the user's eye socket. The sealed air-tight ocular cavity can be pressurized to take ocular measurements. The mask can conform to the contours of a user's face by inflating or deflating the mask. In addition, the distance between the user and a medical device (e.g. an optical coherence tomography instrument) can be adjusted by inflating or deflating the mask. Also disclosed herein is an electronic encounter portal and an automated eye examination. Other embodiments are also described.
