Features

The Canon Digital Retinal Camera CR-2 takes digital photographic retinal images of patient’s eyes across an angle of view of 45 degrees, in a naturally dilated state without using mydriatics. The CR-2 has the following features:

Reduced flash intensity

The CR-2 can take images at ISO 800/1600 at the standard flash intensity, and ISO 3200/6400 in low flash intensity mode. This reduces patient discomfort caused by light glare.

Compact, user-friendly design

The CR-2 is designed to be even smaller, more lightweight and compact than the previous model. This makes it easier to assist patients and provides significant ease of operation.

An operation lever has the integrated functions: vertical movement of the main unit, switching between anterior segment and fundus, and manual focusing. This lever significantly improves alignment operability.

Special digital camera

The CR-2 is equipped with a special digital camera using EOS digital technology. This enables the CR-2 to fully maximize Canon technology for shooting high-quality, high-resolution diagnostic images.

Small pupil photography function

The CR-2 captures retinal images through pupils of the normal diameters from 4.0 mm. This small pupil photography function permits image to be captured through pupils from 3.3 mm in diameters.

System optimized for digital photography

With the supplied imaging control software, the photographed images can be browsed, processed, stored, output to the DICOM storage server, exported in DICOM or JPEG format and output to a printer.

In this manual, the operation procedure is described with the Retinal imaging control software NM 2 (referred to as “Rics NM 2” ).

Indications for Use

For USA

The device is intended to be used for taking digital images of the retina of the human eye without a mydriatic.

For European Union

This medical device is intended to observe and record images of retinal fundus through the pupil without making contact with subject’s eye for the purpose of diagnosis by way of producing fundus image information.
