Fundus Camera

2D/3D Non-mydriatic Retinal Camera / Analysis System

Kowa nonmyd WX

Special Contents >>

A new concept retinal camera with "SSP",
Simultaneous Stereoscopic Photography

3 photography modes to choose from: Normal, SP(Small Pupil), and Stereo

2D - Normar & SP -

Normal Field angle:45°

Kowa's exclusive optical design in combination with the digital SLR camera delivers extremely detailed retinal images.
The integrated 9-points internal fixation light allows for mosaic photography covering a large retinal area.

SP(Small Pupil) Field angle:45°

Retinal images can be taken even with smaller pupils. On screen guides indicate if the pupil size is within the sufficient range (above φ3.5 mm) for photography.

Automatic mosaic merge function
Mosaic images are created easily with automatic image rotation & alignment.

3D - Stereo -

SP(Small Pupil) Field angle:45°

Photography
Instant and simultaneous 3D photography is possible in 1-shot.
Retinal observation on 3D images
The shape of the optic disc and cup can be viewed on a 3D image.
Switch between the parallel and cross viewing methods with 1-click when viewed on a 2D monitor.
Time sequential movie
The chronological change of the shape of the optic disc and cup can be viewed on a moving image.

3D Analysis System

Photography
Start up the analysis system at the display of stereo image.
Contour line determination(manual/auto)
Disc and cap are plotted manually or automatically to support contour line determination.
3D analysis
The analysis result is shown by the various parameters in the specified area.
  • ① Depth distribution
  • ② 3D display
  • ③ Numerical data of analysis results
  • ④ Polar coordinates display
  • ⑤ Contour line depth distribution graph
  • ⑥ Follow-up
Report output(PDF/JPEG)
The analysis result can be output in PDF and/or JPEG format.
Depth distribution ①

Color-coded display of the depth distribution in the analysis area, or graphical display of the cross section of an arbitrary position.

3D display ②

Display of 3D image based on stereographic data.

Numerical data of analysis results ③

Display of optic disc parameters including "DDLS".

Polar coordinates display ④

The polar coordinates display of the depth distribution permits visual display of the thin part of the rim. (marginal region of optic disc)

Contour line depth distribution graph ⑤

Graphical display of the depth distribution of disc and cup profiles.

Follow-up ⑥

Graphical display of cup/disc ratio, rim/disc ratio, cup area, and many other parameters.

DDLS(disk damage likelihood scale) Stage

Indexical values defined by the disc size and the rim/disc ratio; which was suggested by Dr. George L. Spaeth as a method to diagnose the optic disc.
