File Functions 10-3
The COMPARE TESTS feature subtracts the results of two threshold tests and indicates the decibel
difference at each point. This comparison is useful, for instance, for tracking the deterioration in a
patient’s visual field on tests for which STATPAC is not available. The results are displayed on the
screen and may be printed.
The SPECIFY PATIENT FOLDERS feature provides one of four possible methods that you can use to
create Patient Folders for a network. Patient Folders allow you to organize computerized patient
data in a way that is similar to using manila file folders to organize a file cabinet full of printed out
test results. For further details regarding all the possible methods for creating Patient Folders, please
refer to the Networking chapter section entitled
“Using Patient Folders,” on page 14-25 .
The COPY TESTS command copies any number of tests from one storage medium to another. This
can provide a simple method for moving a small number of files from one perimeter to another.
The MOVE TESTS function transfers tests from one storage medium to another. Unlike the Copy
function, this function deletes the selected test(s) from the source disk at the same time that it
moves them to the destination disk.
The DELETE TESTS function permanently erases tests from a storage medium. A confirmation
window will appear prior to your final deletion of the data. This allows you to cancel the operation if
necessary.
Use the TRANSFER TESTS capability to move tests from an older Humphrey Field Analyzer model
(either the HFA I or an earlier HFA II) to the HFA II-
i
series instruments. You may also transfer tests
between an HFA II-
i
and a second HFA II-
i
. You can do this using the instrument’s network
connection or by connecting a serial cable to the Data Transfer ports of two HFA’s. Once your
network or serial cable connection is made, you can use the TRANSFER TESTS command. The proper
serial cable connection is required to connect the instruments directly. You can transfer
approximately 1,440 tests per hour at a 9600 baud rate, using a direct cable connection between
two HFA’s. For further details, refer to
“Serial Transfer of Tests Between HFA I, HFA II or HFA II-i
Instruments,” on page 10-19 .
The BACK UP/RESTORE function allows you to back up or save tests stored on the hard disk to either
a USB storage device or a network file server. Neither backup method allows the user to pick and
choose which tests should be backed up. The entire database will be backed up. Use this same
feature to restore information to the hard disk from a floppy disk, USB storage device, or network
file server, if necessary. Extensive information on the BACK UP/RESTORE feature is found in
Chapter (11), "Database Management." Be sure you use only formatted disks. It is important to
backup all of your databases regularly, to ensure that you can access all of your tests even if the
originals become damaged or lost.
Note: Backing up tests will erase previous database backup information on the destination and
replace it with the information from the source.
