ORGANIZING
PATIENT FILES
Just as you organize patient tests that are on paper, it is also necessary to organize visual field
tests on floppy disks. The system chosen depends upon the quantity of patients to be tested.
Keep in mind that each floppy holds 100 to 500 tests, depending on test type. Clearly label
every disk and/or magneto-optical disk in your test library.
1. Keep a floppy disk in the drive at all times in order to maintain a chronological copy of all
tests. Each time you press SAVE ON DISK, the results will be stored on both the hard disk
and floppy disk.
2. Organize floppy disks chronologically by leaving the same floppy disk in the drive until it
is full and then replacing it with a new, initialized disk. Clearly label every disk in your file
library with the starting and ending dates contained on that floppy.
3. Always print a hard copy of test results for all tests not saved to disk.
4. Periodically make copies of the floppy disks to protect the data.
Note: It is recommended that you store a copy of your HFA II database outside of the office
to protect your data from unforeseen damage.
Be sure to read the next section: “Database Management” for more information on
the importance of maintaining good data backup techniques.
