My GDx Nerve Fiber Analysis Results

Submitted by dave on Wed, 01/21/2009 - 9:02pm

Here are my GDx Nerve Fiber Analysis results from my eye exam today. The results are slightly better than my last GDx exam as well as my GDx exam from about two years ago. At this point I doubt we can say anything concrete about the significance of the positive change except that things are certainly not getting worse! Big Smile

Learning to Interpret My Heidelberg Retina Tomograph (HRT-II) Results

Submitted by dave on Fri, 01/26/2007 - 12:19pm

My doctors are responsible for the real intrepretation of my Heidelberg Retina Tomograph (HRT-II) results. However, being a curious person, I like to understand the results myself. This blog post is my attempt to share what little I know about HRT results so far.

I have made my HRT-II results from 2006 and 2007 available online:

I wonder if it is possible to guess about the rate of progression of my optic nerve damage (in my right eye) using my existing test results. Unfortunately, over the last 2.5 years since my diagnosis, my optic nerve analyses have not all been performed with the same instruments. However, given the available information, I'm wondering if it is possible to guess whether the rate of damage is slowing since the beginning of 2006 or not.

I have had either a GDx or an HRT test on the following dates:

My Heidelberg Retina Tomograph (HRT-II) Results for 2007

These are my HRT results from today, 19-January-2007. This test was performed with an HRT-II, which is the same model used for my HRT test in 2006. However, today's tests were done by a different doctor (and different HRT operator) -- in fact, they were done in a different country.

Upon a quick examination, the doctor didn't seem to think there was much progression over the last year. However, I expect further input in the coming weeks.

All Your Efforts Measuring Pressures Are A Waste

 A friend referred me to a new ophthalmologist who lives in another city. I corresponded with this new ophthalmologist via email. I am not replacing my current ophthalmologists, merely seeking additional input on specific issues where experts are few and far between.

However, I guess many facts did not get communicated clearly in my various emails to the doctor. The doctor sent me this email reply today (and I edited what is posted here):

My Heidelberg Retina Tomograph (HRT-II) Results for 2006

These are my HRT results from 2-January-2006. Look for my next HRT results around the end of January 2007.

This test was performed with an HRT-II. The HRT is a Heidelberg Retina Tomograph (also called scanning laser tomograph). It is made by Heidelberg Engineering, a German company.
