The Non-Mydriatic Cobra HD Retinal Camera - examining the ocular retina without the need for pupil dilation.
This digital fundus camera offers a comprehensive solution for the rapid screening of retinal conditions, thanks to its innovative optical system that captures high-quality images of the retina.
The Cobra HD is ergonomically designed to ensure comfortable image acquisition for the patient. It provides a clear and detailed view of the retina with a field of view of up to 50 degrees. Minimal flash exposure allows for quick and detailed retinal imaging while minimizing discomfort for the patient.
This camera uses a high-resolution 5-megapixel CCD sensor for patient alignment (with infrared illumination) and retinal image capture (with white-light flash and infrared LEDs). The USB connection between the device and the computer allows for fast and easy image transfer. Patient data is stored in the Phoenix patient management software, in standalone or network configuration, and it is also possible to enable a DICOM connection for image transfer.
The Cobra HD also offers comprehensive dry eye syndrome analysis based on the Ocular Surface Disease Index (OSDI) questionnaire, assessment of limbal and conjunctival ocular redness, Meibomian gland analysis, tear meniscus analysis, non-invasive tear film breakup time (NIBUT), and tear osmolarity measurement. These evaluations provide a comprehensive assessment of the patient's clinical condition for a complete diagnosis of dry eye syndrome.
The retinal camera can display images at multiple wavelengths on a single screen, including the original image, infrared image, red-free image, as well as choroidal, vascular, and nerve fiber images.
Optionally, the Cobra HD offers an AVR (arteriole-to-venule ratio) assessment module that measures the relationship between arteriole and venule diameters. A low ratio between vessel dimensions may be predictive of cardiovascular issues in adult patients.
The mosaic function of the Cobra HD allows for the acquisition of multiple images to create a panoramic image of peripheral retinal areas.
Infrared image acquisition uses a low flash level and infrared light, producing a highly detailed image of the retina.
Finally, the device allows for cup-to-disk (C/D) ratio measurement for the detection of glaucomatous diseases through measurement tools integrated into the Phoenix software platform.
