Stereoscopic display systems and methods for displaying surgical data and information in a surgical microscope are disclosed herein. According to an aspect, a system includes first and second eyepieces. The system includes a display having first and second display portions, configured to display first images in the first display portion, and configured to display second images in the second display portion. The first image and the second image are projected along a first pathway and a second pathway. The system includes a first optical element positioned to relay the first images into the first eyepiece. The system includes a second optical element positioned to relay the second images into the second eyepiece.

The tomographic image capturing device of the present invention includes a tomographic image capturing means that scans measurement light on a subject's eye fundus (E) to capture tomographic images of the subject's eye fundus and an image processing means that compresses a picture of the captured tomographic images in a scan direction to generate a new tomographic picture. The tomographic image capturing means performs scan at a second scan pitch (P.sub.L) narrower than a first scan pitch (P.sub.H) to capture the tomographic images of the subject's eye fundus. The image processing means compresses the picture (B11) of the tomographic images captured at the second scan pitch (P.sub.L) in the scan direction to generate the new tomographic picture (B12). The measurement width in the scan direction of the new tomographic picture (B12) is a width of a picture corresponding to a measurement width in the scan direction of a tomographic picture (Bn (n=1 to 10)) obtained by scan at the first scan pitch (P.sub.H).

The length of an optical fiber from a portion aligned with the rear end of an insertion needle to a fixing portion is a length obtained by adding a predetermined extra length to a linear distance between the rear end of the insertion needle in a case where the insertion needle is located at a protruding position (insertion position) and an optical fiber fixing position of a grip portion. There is provided a fiber feeding adjustment mechanism that suspends the optical fiber with a first suspension portion and a second suspension portion so as to make a detour in a state in which there is no slack, and changes the detour length continuously according to the movement of the insertion needle in a case where the insertion needle moves between the retracted position and the protruding position, thereby maintaining a state in which the optical fiber is suspended without slack.

The present technology relates to an image processing device, a method of image processing, and a surgical microscope that can detect and report a dangerous condition on the basis of a tomographic image during eye surgery. An image processing device includes: a dangerous condition detection unit configured to detect a dangerous condition on the basis of a tomographic image of an eye acquired during surgery of the eye; and a control information generation unit configured to generate and output control information used to manage the detected dangerous condition. The present technology is applicable to, for example, a surgical system used for eye surgery or other surgical procedures.

A method of laser eye surgery including linking retinal vessel architecture to corneal topography. This enables registration of the steep axis of the cornea in order to orient a toric intraocular lens, and/or to place astigmatic keratotomy incisions. First, a detailed pre-operative retinal image of the vasculature of the retina is obtained. In addition, a pre-operative image of the topography of the eye is obtained. The retinal image is then correlated or superimposed on the topography image to provide a reference. After the patient lies down under the laser eye surgery system, and during the surgery, the retinal vasculature is monitored which provides a reference to the surgery system about the topography of the eye. This process enables registration of the steep axis of the cornea in order to orient a toric intraocular lens and/or to place astigmatic keratotomy incisions.

An optical coherence tomography (OCT) system using partial mirrors is generally described. In an example, the OCT system includes a swept light source. The system further includes an interferometer into which light from the light source is directed and a detector configured to produce an imaging sample signal based on light received from the interferometer. The system also includes a partial mirror disposed over an aperture, wherein the partial mirror is configured to transmit light within a first wavelength range and reflect light within a second wavelength range.

The present invention provides compounds and methods for the treatment of LFA-1 mediated diseases. In particular, LFA-1 antagonists are described herein and these antagonists are used in the treatment of LFA-1 mediated diseases. One aspect of the invention provides for diagnosis of an LFA-1 mediated disease and administration of a LFA-1 antagonist, after the patient is diagnosed with a LFA-1 mediated disease. In some embodiments, the LFA-1 mediated diseases treated are dry eye disorders. Also provided herein are methods for identifying compounds which are LFA-1 antagonists.
