Methods, apparatus, and systems for performing an ophthalmic diagnostic test are disclosed. In one aspect, a head-wearable device for administering an ophthalmic test to a subject can comprise a head-wearable frame for mounting the device onto the subject's head, and a light seal configured for coupling to the frame so as to isolate at least one eye of the subject from ambient light when the device is worn by the subject.

An ophthalmologic examination system that examines a subject's eye with an ophthalmologic apparatus includes an information acquisition portion that acquires a patient's ID determined for each patient and an examination order determined for each patient, an information storage portion that stores the patient's ID and the examination order which are obtained by the information acquisition portion and are linked, an ID reception portion that receives input of the patient's ID, an order read-out portion that reads out the examination order linked to the patient's ID received by the ID reception portion from the information storage portion, and an examination control portion that sets the ophthalmologic apparatus to at least an examination ready state based on the examination order read out by the order read-out portion.

A mobile ophthalmic unit is disclosed. The apparatus is comprised of the following components: a phoropter on an adjustable arm, an extendable slit lamp, an ophthalmoscope with controller, desktop or a laptop computer (or both) with or without a detachable screen or a tablet computer, a WiFi router and an internet hotspot. All of the aforementioned components are connected to a mobile desk having locking caster wheels. An object of the invention is to allow an eye care specialist to visit patients in the field and perform routine eye exams remotely rather than requiring patients to travel in order to obtain eye care. For example, the ophthalmologist can easily roll the apparatus into a cargo van and drive to an underserved population and deliver eye exams where no such facilities exist—thereby enhancing eye care for a community.

A concise representation illustrating essential elements of a subjective refraction eye test that includes choices of optics offered to a test subject, responses by the test subject indicating respective choices among the optics, and time durations of, between, or both of and between, responses by the test subject indicating the respective choices of optics. The concise representation includes a presentation that illustrates the essential elements of the eye test.

A system for capturing one or more eye images includes an eye imaging device having a camera configured to capture the eye images. The system determines a workflow for capturing the eye images using the eye imaging device. The workflow is determined based on a risk score for a given patient. The system performs the workflow on the eye imaging device to capture the eye images, conducts a microvascular assessment based on the captured eye images, and adjusts the risk score based on the microvascular assessment.

The present disclosure provides improved techniques for imaging and/or measuring a subject's eye. Various aspects of the present disclosure relate to relate to an imaging and/or measuring apparatus. Some aspects of the present disclosure relate to an imaging and/or measuring apparatus configured to capture an image and/or measurement of a subject's eye, the imaging and/or measuring apparatus comprising: a plurality of illumination optical components comprising a spatial filter; and an objective lens configured to transmit and/or receive light with a field of view of the subject's eye. Some aspects of the present disclosure relate to a method of imaging and/or measuring a subject's eye, the method comprising: generating an annular illumination profile; attenuating a portion of the illumination profile using a spatial filter; and transmitting the attenuated illumination profile to a subject's retina fundus using an objective lens.

According to a method for determining metamorphopsia based on user interaction disclosed as an embodiment of the present invention, a test chart may be displayed to a user, an input from the user for a part which is perceived as being distorted in the displayed test chart may be received, and a metamorphopsia degree of the user may be accurately determined based on a distortion area selected according to the received input. Further, according to another embodiment of the present invention, a test chart may be displayed to a user, a response (e.g., distance values of points, an area value, etc. in a zone) for each zone for the test chart may be received from the user, and metamorphopsia of the user may be determined based on the received response.

An ophthalmologic information processing apparatus includes an acquisition unit, a tissue specifying unit, and a specifying unit. The acquisition unit is configured to acquire a tomographic image of a subject's eye formed based on scan data acquired using an optical system for performing optical coherence tomography on the subject's eye. The tissue specifying unit is configured to acquire first shape data representing shape of a tissue of the subject's eye by performing segmentation processing on the tomographic image. The specifying unit is configured to specify a low sensitivity component having a small variation with respect to a change in a position of the optical system with respect to the subject's eye from the first shape data, and to obtain second shape data representing shape of the tissue based on the specified low sensitivity component.
