Canon CR-2 PLUS AF

The Canon CR-2 PLUS AF Digital Non-Mydriatic Retinal Camera provides Color and Fundus Autofluorescence (FAF) imaging within a small compact design. Features include Auto-Fundus, Auto-Focus, Auto-Capture and Image Error Detection. Geographic Atrophy, Macular Degeneration, Glaucoma, Diabetic Retinopathy and other conditions that can affect vision may also be identified and monitored using FAF mode. Using invisible infrared alignment light, the digital non-mydriatic camera may image patients with pupils as small as 3.3 mm (small pupil mode) without dilation drops. This is especially useful when performing retinal screenings or expediting routine retinal imaging exams during office visits.

 

Key Features

  • Auto-Focus with Manual Alignment Override: Automatically focuses the eye by partially depressing the joystick, or easily switches to manual focus with a twist of the focus ring.
  • Auto-Capture: Automatically captures the image once the eye is properly focused.
  • Auto-Exposure: Automatically measures the volume of infrared light at the retina and adjusts the flash intensity.
  • Auto-Fundus: Automatically switches from the external eye to retinal observation mode when the eye is properly aligned.
  • Image Error Detection: Advanced software automatically confirms both correct alignment and focus.
  • Contrast Enhancement: Provides increased image clarity by emphasizing the difference in ‘redness’ and ‘brightness’ of blood vessel structures relative to their surroundings.

Description

SHORT REACHING DISTANCE

The compact design allows the operator to easily keep the patient’s eye open with one hand and permits an excellent view of the patient’s eye.

 

ERGONOMICS

Specially shaped surface to act as grip; easy handling for quick and efficient image capture.

 

MULTIFUNCTIONAL JOYSTICK

    Up and down movement of optical head (powered) and focus ring.

     

    VARI-ANGLE LCD SCREEN

    For optimized viewing angles, so camera can be operated while seated or standing up.

     

    EXTENSIVE AUTO FUNCTIONS

    • Auto Focus: Fast and accurate automatic focusing.
    • Auto Shot: Once the alignment, working distance and focus are correct, photography is done automatically.
    • Auto Switching from Anterior to Retina: When aligned correctly on the pupil, the camera will automatically switch to retinal observation view.
    • Photometric Auto Exposure: Flash and observation light intensity is set automatically for every examination, based on retina reflectance, for perfect images regardless of pupil size or ethnicity.
    • Full Control: The auto functions will make the procedure much easier. Nevertheless for patients with ocular opacities, involuntary eye movements, lack of co-operation and small pupils, the possibility of full manual control is crucial. Manual operation frequently overcomes the limitations of fully automatic cameras.

     

    PHOTOGRAPHY MODES

    • Color: High quality 45 degrees image. 2 X digital magnification.
    • Digital Red Free and Digital Cobalt: Automatically created from the original RAW color image. Based on the EOS retina technology and Canon proprietary image processing. Image quality comparable with optical filters.
    • Anterior Photography: Quick and easy anterior segment photography to document the cornea, pupil, eyelid and sclera.
    • Fundus Autofluorescence (CR-2 Plus AF only): FAF imaging for the diagnosis of retinal disease is a relatively new diagnostic technique that provides more information on the health of the retinal pigment epithelium. FAF has proven to be very useful for the early detection of Age-related Macular Degeneration (AMD), one of the leading causes of visual impairment. Recent studies indicate that FAF imaging can also aid the diagnosis of a variety of other diseases and even detection of intraocular tumors.

     

    UNRIVALED IMAGE QUALITY

    • Dedicated 32.5 Mega Pixel EOS camera: Canon’s own EOS camera technology, with its renowned image processing capabilities, is adapted exclusively for Canon retinal cameras, it provides optimal retinal imaging.
    • Resolution: Important factor that contributes to a high image quality is the number of pixels per square mm. When comparing our 32.5 megapixel with e.g. a 4 megapixel camera, the illustration clearly shows the additional information that is gained.
    • Contrast Enhancement: Utilizing the EOS retina technology, this contrast enhancement function emphasizes the differences in brightness and redness of blood vessels and their surrounding areas, resulting in clear, high-quality images.

     

    CANON OPACITY SUPPRESSION

    When obtaining retinal images, ocular opacities will cause several problems: the scattering of the light will make the edges of the blood vessels appear blurred. The difference in brightness of the retina will be reduced, making it very difficult to distinguish between structures. And a cataract eye will cause images to appear more yellow.

    With Canon’s unique and sophisticated opacity suppression tool the blood vessels will appear much clearer; the original brightness of the retina will be restored and any change in retinal color will be compensated.

    With Canon Opacity Suppression (COS) the effect of ocular opacities will be largely suppressed: previously unsuitable images could now provide you with essential clinical information!
