Can EM 935 software handle measurement of endothelium with guttata
Measuring eyes with guttata is a challenge for all specular microscopes as the software has trouble differentiating the difference between a cell and guttata. The best and fastest method is to measur...
- What is the EM 935
EM935 is a slit lamp mounted endothelium microscope designed to make a rapid, automatic analysis of the corneal endothelium and conveniently fits onto most slit lamps. Image capture is automatic and a...
- Can the EM935 do any other high magnification imaging (i.e. lens pathology)
The EM935 has been designed specifically for specular reflectance images of the corneal endothelium. As it is around 200 x magnification it is not much used for anything else. In theory it could be us...
- Possible to use the EM935 for corneal grafts
The EM 935 is designed to measure the corneal endothelium ‘in vivo’ and as such has not been used on graft donor material or eyes. There are instruments available for this specialized wor...
- Can the EM935 do any other high magnification imaging (i.e. lens pathology)
The EM935 has been designed specifically for specular reflectance images of the corneal endothelium. The magnification of ~200 x limits the use for other types of imaging. Some users have expressed...
- What is the accuracy of the EM935
...uracy of the ME 935 is defined
as 747Pix/mm +/- 2.5%.
Best reproducibility is achieved if the
endothelium images are analyzed in a semi automatic manner. This means the
images are taken automat...
- Is it possible to measure the endothelium through swollen or opaque corneas
...ornea is compromised then this will affect the image quality. It may still be possible to image the endothelium through corneal oedema but we advise that you examine the data carefully and check the c...
- Can EM 935 software run on a touch panel pc
The processing power required by the EM935 is minimal and therefore any PC or laptop should be capable. If the Firewire port is not powered (i.e. on most laptops) then the power supply for the camer...
- Can we place the EM935 on the left hand side
No. This is not possible because the software is programmed to search for the corneal reflex on the left of specular endothelial reflex.
- Can I use longer lengths of Firewire cables
The maximum cable length is 5m. Longer lengths will reduce the transfer speed and this will cause problems. Always use a good quality cable.
- Error "This unlicenced copy of IMAQ Vision may be used for demo purposes only" comes up
Please install the runtime license from CD. Look at Folder x:\Run-Time-License and start the Program vision61rte.exe
- Alignment mode, with slit on 0.2 no image does appear, but on 3mm it does
Base plate height is not set correctly. Possibly the wrong base plate used, contact our service department.
- Alignment mode holding hand in front of the lens image is grey
In Alignment mode the image on the screen should be black. If it is otherwise (grey) the sensitivity of the camera is not correct. Please contact our service department.
- In Alignment mode, slit does not become narrow but fades out
Check if the base plate/pin is well connected and unit is centered. If this is the case and you have still problems, please contact our service department.
