1. Features The Digital Retinal Camera CX-1 is used to observe the retinas of patients’ eyes and take photographs of them. The camera has the following features:

Both mydriatic and non-mydriatic modes in a single unit The CX-1 includes a mydriatic mode and non-mydriatic mode; and each mode can be selected with a single switch. In the mydriatic mode, the optical viewfinder is used for observation. In the non-mydriatic mode, the observation monitor on the special digital camera is used for observation.

Fundus autofluorescence photography Fundus autofluorescence photography is possible in both mydriatic and non-mydriatic modes.

Special digital camera The CX-1 includes a special digital camera using EOS digital technology as a standard accessory. This enables the CX-1 to fully maximize Canon technology for shooting high-quality, high-resolution diagnostic images.

Compact, user-friendly design Panning and tilting functions are provided as standard features in a compact, lightweight design. The compact body makes it easier to assist patients and provides significantly improved ease of operation. Vertical movement of the main body by a motorized chin rest and an operation lever significantly improves alignment operability.

Small pupil photography function The CX-1 can photograph dilated pupils with a diameter of at least 5.1 mm in the mydriatic mode, with 50° of their field angle. It can photograph non-dilated pupils with a diameter of at least 4.3 mm in the nonmydriatic mode, with 45° of their field angle. The CX-1 provides the small pupil photography function for patients whose eyes are difficult to dilate. Using this function, it can take photographs of dilated pupils with a diameter of at least 4.3 mm and nondilated pupils with a diameter of at least 3.8 mm.

System optimized for digital photography With the Retinal imaging control software (called “control software” below), images photographed by the CX-1 can be browsed, processed, stored, output to the DICOM storage server, exported to DICOM files, and output to a printer. The settings for the lighting system filter, flash intensity, and digital camera are automatically optimized for each photography mode – color, red-free, cobalt, fluorescein angiography, or fundus autofluorescence.
