A method is provided for determining the dominant eye of a person using equipment designed to acquire at least one image of the face of the person, then process the image, and finally return information enabling the person to know which eye is the dominant eye thereof. The method uses a sighting device that is identifiable and locatable in relation to the equipment, with the viewing being carried out through a window with both eyes open. The size of the window is such that it does not allow the person to see said target with both eyes at the same time. The equipment acquires at least one image for viewing the position of both eyes of the person, processing the image by performing calculations while taking into account the position of a central point located between both eyes, the position of the target and the position of the window.

A retina viewing system and method of using the same includes an ophthalmic microscope, a disposable lens attachment, and an electronic control unit (ECU). The microscope has an optical head and a set of internal focusing lenses, the latter providing the microscope with a variable working distance or focal length. The disposable lens attachment includes a resilient body with a proximal end connected to the optical head and a distal end connected to a high-power/high-diopter distal lens. The ECU executes instructions for viewing a retina or other intraocular anatomy of a patient eye. Execution of the instructions causes the ECU to automatically adjust the variable working distance or focal length of the microscope when viewing an image of the retina through the distal lens.

In some implementations, a font generator device may receive input text that includes one or more characters. The font generator device may generate a disability-oriented font based on one or more parameters that relate to a vision deficiency, wherein the disability-oriented font is readable by users that have the vision deficiency and unreadable by users that do not have the vision deficiency. The font generator device may transform the one or more characters included in the input text into the disability-oriented font. The font generator device may generate an output that represents the input text using the disability-oriented font based on transforming the one or more characters included in the input text into the disability-oriented font.

An apparatus for OCT-based imaging, a microscopy system and a method for operating a microscopy system, include at least one OCT radiation source and at least one connection device for connecting the apparatus to the microscopy system, an optical connection configured to be established between the OCT radiation source and the light-guide element of the apparatus in a connected state, wherein the microscopy system includes means for detecting a connection state change, and a change-conditional adjustment of the mode of operation of the microscopy system being performable upon the detection of a connection state change.

In a method for testing a disposable on a medical examination appliance, more particularly on a tonometer, wherein the medical examination appliance comprises a disposable holding apparatus, on which a disposable is held and, in particular, able to be brought into contact with a patient's eye for an applanation tonometry measurement, and which comprises a detection device, by means of which a physical property of the disposable can be measured, a measured value of the physical property of the disposable is ascertained by means of the detection device.

Provided are systems and methods for noninvasively assessing intracranial pressure by controllably osculating at least a portion of a subject's ocular globe while applying a force sufficient to collapse an intraocular blood vessel and correlating the collapse pressure to intracranial pressure. Also provided are ophthalmic components useful in ophthalmic imaging applications, such as retinal, corneal, and pupil imaging. The components may include an optical contact surface that has a radius of curvature that is greater than the radius of curvature of a subject's cornea.

An ophthalmic apparatus of an exemplary embodiment includes a storage and a difference processor. The storage stores a plurality of pieces of angiographic image data acquired by applying optical coherence tomography (OCT) angiography to the fundus of a subject's eye a plurality of times. The difference processor generates difference data between the first angiographic image data and the second angiographic image data both read out from the storage.

There is provided a target presentation device for presenting a target to a subject eye. The target presentation device including a format setting means that sets a display format of a visual acuity value of an examination target used in an examination of the subject eye, based on an operation signal, and an output means that outputs a target to be presented to the subject eye, based on the visual acuity value represented in the display format set by the format setting means.
