Definitions

  • a slit-lamp biomicroscope In ophthalmology, a slit-lamp biomicroscope is generally used as a fundamental diagnostic device to view and assess the anterior and posterior segments of the eye.
  • examination with a slit-lamp biomicroscope must be performed by a specialist, such as an ophthalmologist or optometrist, in person. That is to say, the specialist performing the examination and the patient must be at the same location since the specialist must be able to view into the eye of the patient with sufficient detail and clarity to perform the diagnosis.
  • a remote operator is able to alter the angle between the stereo-microscope and the slit-lamp, a crucial function for adequate ophthalmic examination, and/or is able to control most if not all of the slit parameters (height, width, intensity) and the biomicroscope magnification changer, all functions that are necessary for adequate examination of details in the structures of the eyelid, eyelashes, conjunctiva, limbus, cornea, anterior chamber (cell/flare), its angle, the iris and the crystalline lens or artificial intraocular lens if the patient had undergone cataract extraction with intraocular lens (IOL) implantation.
  • IOL intraocular lens
  • Figure 1 is a schematic representation of the system for ophthalmic imaging of the present invention.
  • Figure 6D is a perspective view of the magnification control of the slit assembly of the ophthalmic device of Figure 3.
  • stereoscopic images including offset polarized images, multi color images and/or other types of 3-D imaging as may be developed, may also be utilized and communicated to correspondingly configured displays capable of displaying such images for three dimensional viewing utilizing corresponding integral, separate or wearable viewers.
  • overlapping image types of stereoscopic viewing must split resolution over the two images and are often difficult to view and/or are distorted if not viewed using a specific viewer from a specific angle.
  • a binocular fusion type of stereoscopic image is presently preferred in the present invention.
  • the viewer 40 comprises at least one prism 42 to enable the combination of two images into a fusion three- dimensional image.
  • the preferred pair of prisms 42 are configured to direct one of the two images to each eye in a manner wherein each eye generally views only a single image and wherein the prisms 42 direct the images onto the eye in a manner that causes the two images to appear in the generally same place and thereby provide the stereoscopic appearance required by the practitioner ( s ) to effectively view the depths of the patient's eye and properly diagnose certain conditions.
  • the image data is transmitted by the processing assembly 60 to the control device (s) 20, where it is presented on the associated display 21.
  • the image data from the image capture member(s) 51 can simply be transmitted by the processing assembly 60 as it is received. Regardless of the embodiment, however, the processing assembly 60 transmits in the aforementioned image data in real-time.
  • a servo interconnects the second positioning member 73 with a slit height adjustment member, discussed in greater detail below.
  • the system for optimized stereoscopic viewing 200 further comprises at least one viewer 40 as described previously.
  • the viewer 40 is disposable at a predetermined distance b, b' from the display 21. More specifically, the viewer 40 is disposable a first predetermined distance b from the display 21.
  • the first predetermined distance b is defined as a short-range distance.
  • the first predetermined distance b is defined as in the range of about 50.8 centimeters to 88.9 centimeters. It should be appreciated that the limits of any range provided herein should not be interpreted strictly, and that distances falling slightly outside the range are still within the intended scope of the invention.
  • first predetermined distance b is defined as in the range of about 55.9 centimeters to 76.2 centimeters.
  • a comfortable viewing distance for a laptop computer is approximately 55.9 centimeters
  • a comfortable viewing distance for a desktop computer is approximately 76.2 centimeters.
  • the first predetermined distance b is the typical distance in which a user sits in relation to a computer monitor, such as a desktop or laptop computer.
  • the first predetermined distance b is defined as less than 50.8 centimeters, such as in the case of viewing a display 21 on a smartphone, tablet device, or other handheld computing device.
  • Formula I demonstrates the relationship between the chief ray angle, prism refractive index, interpupillary .distance, the distance from the eye to the object, and the prism angle for optimized stereoscopic viewing at a number of differen viewing distances:
  • prism angles ⁇ are approximations, such that slight variations therefrom are contemplated.
  • a prism angle ⁇ of 10.2° or 24.7° are within the spirit and scope of the present system 200.
  • prisms 42 made of different materials with different indices of refraction different ranges of prism angles ⁇ will apply.
  • a viewer 40 having a prism angle ⁇ of 16° may also be used in parts of the first viewing area 222 and will produce a fused image, but the stereoimage produced will not have as much depth detail as other prism angles ⁇ could produce in that viewing area. Accordingly, there is an overlap of prism angles ⁇ possible for each viewing area.
  • a viewer 40 having prisms 42 with prism angles ⁇ in the range of 13.6° to 18.4°, but preferably 16°, will optimally enable stereoscopic viewing at predetermined distances falling in second viewing area 224, which is defined as between approximately 8 meters and 10 meters from the display 21.

Abstract

La présente invention concerne un système d'imagerie ophtalmique comprenant un dispositif ophtalmique permettant l'obtention d'images stéréoscopiques de l'œil d'un patient et la transmission en temps réel par un réseau desdites images en direction d'un dispositif d'affichage en vue de leur observation par des praticiens utilisant une visionneuse combinant lesdites images en une seule image stéréoscopique de l'œil. Ledit dispositif ophtalmique comprend au moins un ensemble optique, un ensemble de traitement, un ensemble à fente, par exemple une lampe à fente, et un ensemble de positionnement. Des dispositifs de commande conçus pour commander le dispositif ophtalmique à travers le réseau, par exemple la Toile, peuvent être disposés en plusieurs lieux et être situés à distance du dispositif ophtalmique tout en permettant une commande en temps réel des paramètres du dispositif ophtalmique par le ou les praticiens impliqués.
