Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

An optical imaging device includes a support structure and imaging channels, where each imaging channel includes a discrete optical imaging pathway. The imaging channels may be disposed within the support structure, and the imaging channels may be aimed at different angles relative to each other such that each optical imaging pathway is directed towards a pupil of the eye. Additionally, the optical imaging device may include a primary fixation target configured to emit optical signals along a primary fixation target projection path towards the pupil of the eye. Further, an artifact of the primary fixation target may be generated onto a portion of the eye to be imaged.

A device is provided that may include an illuminator operable to interrogate at least a lens of an eye. The illuminator may include at least one light source and a lens positioned with respect to the light source to produce interrogating radiation. The device also may include a detector operable to image the total autofluorescence response of the lens of the eye as viewable through a pupil of the eye, the detector comprising an image sensor. The device can also include a controller operable to control operation of the illuminator and the detector. The controller may interrogate at least the lens of the eye by activating the illuminator for a select time, obtain at least one image of the total autofluorescence response of the lens at the detector during or immediately subsequent to the select time, and transmit the at least one image to a remote device.

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.

[Problem] An object of the present invention is to provide an ophthalmic microscope capable of observing, and acquiring a tomographic image of, an anterior ocular segment and a posterior ocular segment without changing a positional relationship between an objective lens and a subject eye.

Another object of the invention is to provide a function expansion unit capable of incorporating, into an ophthalmic microscope of existing specifications, a function capable of observing, and acquiring a tomographic image of, an anterior ocular segment and a posterior ocular segment without changing a positional relationship between an objective lens and a subject eye.

[Solution] There is provided an ophthalmic microscope including an observation optical system having a first focal point in front of a subject eye; an objective auxiliary lens capable of being set in a position on the subject eye side of an objective lens in the observation optical system or capable of being released from the position, a focal point at a time when the objective auxiliary lens is set being set to a second focal point which is an anterior ocular segment position of the subject eye; and a front lens capable of being set in a position further toward the subject eye side than the first focal point or capable of being released from the position, a focal point through the crystalline lens of the subject eye at a time when the front lens is set being set to a third focal point which is a posterior ocular segment position of the subject eye, the objective auxiliary lens being set and the front lens being released during anterior ocular segment observation, and the front lens being set and the objective auxiliary lens being released during posterior ocular segment observation, without changing a positional relationship between the objective lens and the subject eye.

An immersive display system for eye therapies includes an ophthalmic microscope and: a double video camera, connected to a local network infrastructure; the double video camera oriented for filming the surgery operation; at least one computerized control unit, connected to the local network infrastructure, receiving images from the double video camera and processing them in a three-dimensional digital format; and at least one computerized controller, receiving the images processed by the computerized control unit. Also included is at least one helmet adapted to be worn on the head by the surgeon during the surgery operation, the helmet provided with a viewer arranged before the wearer's eyes, configured for three-dimensional image display, providing virtual reality content; the viewer allows the surgeon exclusive viewing of the three-dimensional images processed by the computerized control unit; the helmet being connected to the local network infrastructure to allow image reproduction in real time.

Optoelectronic binocular instrument for the automatic correction of presbyopia and method for the binocular correction of the presbyopia. The instrument has two optoelectronic lenses (103, 110; 203, 204) and a capturing subsystem for taking images of the eye. By means of the pupil tracking, which performs the processing of the eye's images, the system determines the distance where the subject is looking at. The pupil tracking works at a very high speed, using a high-performance graphic processor and a highly parallelized algorithm for pupil tracking. The method consists of two phases. In the first one a calibration is accomplished, the subject is asked to look at targets at different distances and the size and position of the pupil is measured. In the second phase the correction is performed by the instrument, the system continuously captures and processes images to calculate the correction to apply and, finally, corrects the presbyopia by applying said correction.
