Question
The results of my computerized field tests seem to vary drastically based on skills/interest of the technican setting up the test. I would like to verify if the test is being poorly given or poorly taken by me.
I am trying to find out "how to use the field analyzer in clinical practice, including specific directions & instructions for technicans & patients." One source is the book by N.T.Chopin, R.P.Edwards.
Thanks, Dave

You are right. There are several variables which can affect the field outcome. The machince must be properly set with the proper correction used for your glasses (if any). This correction also has to be placed in the correct position. The technician must moniter the test to make sure the machine is working well and that you are paying attention. If the patient looks away are is not performing the test correctly, the technician can identify this and remedy it.
The results are also matched with age controls so if the incorrect age is entered, the statistical analysis is wrong.
The best source is the handbook which acommpanies the field analyzer. I am not sure how you can get one other than maybe borrowing it from your physician's office.
