I was recently contacted by an old friend who shares the same retinal
imaging system that I do, namely the Digivid 2000 by Helioasis Systems.
Helioasis has gone under and there have been some issues with the
earlier version of its software.  The Helioasis system is a Windows NT
based program that stores the retinal images in one huge collective
file simply called the "image" file.  When we hit our 90 thousandth
retinal image, the software started to crash repeatedly.  The most
common symptom of this crash was that the photographer would create an
image, view it or modify it, and then hit "save" only to find the
program would shut down and drop back to the Windows opening screen.

As it turns out, there is a limitation to the size that a file can be
in Windows NT or 2000, and this ceiling doesn't matter at all for most
software because a well written program organizes its data into folders
and subfolders within the main program file.

I am writing this because I "hit the wall" two years ago, right at the
time that Helioasis was being padlocked by its creditors, and I got a
"work around" solution.  There is a conversion program that
re-organizes the huge "image" file into individual folders that have
each individual patient's names on them.  Once the conversion program
is run, the camera is back to full efficiency and can much more readily
find the patient's past images when you call them up on the screen.

If you have a Helioasis system, or have a friend or employer who uses
one, I am keeping copies of the new software on CDs to help save the
hundreds of thousands of retinal images that could be lost
(collectively) as more and more camera users "hit the wall."

Write to me (doctor_my_eye@msn.com) if you need help patching your
system and I'll burn a CD for you.  A $5.00 solution might save your
$90,000.00 camera.
