A radiosurgery system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, other disorders or tissues of a body are treated with the dose of radiation. In some embodiments, the target tissues are placed in a global coordinate system based on ocular imaging. In some embodiments, the target tissues inside the global coordinate system lead to direction of an automated positioning system that is directed based on the target tissues within the coordinate system. In some embodiments, a treatment plan is utilized in which beam energy and direction and duration of time for treatment is determined for a specific disease to be treated and / or structures to be avoided. In some embodiments, a fiducial marker is used to identify the location of the target tissues. In some embodiments, radiodynamic therapy is described in which radiosurgery is used in combination with other treatments and can be delivered concomitant with, prior to, or following other treatments.

A handheld, ocular imaging device and system that employs the camera, processor and programming of a mobile phone, tablet or other smart device coupled to optical elements and illumination elements that can be used to image the structures of the eye in home-based, ambulatory-care, hospital-based, or emergency-care settings, is presented. The modular device provides multi-functionality (fluorescein imaging, fluorescence, brightfield, infrared (IR) imaging, near-infrared (NIR) imaging) and multi-region imaging (retinal, corneal, external, etc.) of the eye along with the added features of image processing, storage and wireless data transmission for remote storage and evaluation. Acquired ocular images can also be transmitted directly from the device to the electronic medical records of a patient without the need for an intermediate computer system.

An eye imaging apparatus can include a housing, an optical imaging system in the housing, and a light source in the housing to illuminate an eye. The optical imaging system can include an optical window at a front end of the housing with a concave front surface for receiving the eye as well as an imaging lens disposed rearward the optical window. The apparatus can comprise a light conditioning element configured to receive light from the light source and direct said light to the eye. The apparatus can further include an image sensor in the housing disposed to receive an image of the eye from the optical imaging system. In various embodiments, light conditioning element includes at least one multi-segment surface. In some embodiments, the housing is provided with at least one hermitic seal, for example, with the optical window. In some embodiments, time sequential illumination is employed.

This patent provides an eyesight improving device which improves ocular imaging adjustment functions and is easy to use. A user puts the eyes on eyepiece parts 10, and sees a figure displayed on a target 12 by both eyes or one eye by opening or closing blocking device 14. In a state where the user focuses the eye on the figure, the target 12 is moved from a far point to a near point by target movement device 18 and is next moved from the near point to the far point, and this is repeated. In this case, the size of the figure is controlled to be changed in proportion to the distance between the eyepiecepart 10 and the target 12. The user can easily concentrate to focus the eye on the figure during the movement of the target 12. This training activates the ocular imaging adjustment functions of a ciliary muscle, a pupil, vergences and the like resulting with their improvement.

An imaging system for examining the interior structure of the eye at high-resolution under ambient light without the need for chemical dilation of the pupil.

A method and apparatus are disclosed for a method for securing a patient for a medical procedure and specifically for an innovative headrest system for securing a patient for an ocular imaging procedure. The approach avoids the need for linkages and sliding rods and such. Instead, it relies on three independently movable face rests (two for the forehead or temples and one for the chin) each with a deformable cushion that is urged into conformity with the patient's head and chin during an adjustment phase of operation. Once a comfortable position and suitable conforming shape is achieved, the positions of the face rests are rigidly fixed and the shape of the cushions are rendered rigid and non-deformable, by application of a light vacuum, for the procedural or imaging phase of operation.
