May 7th, 2009
Today, we received the results of Carver's VEP (visual evoked potential). This was an eye test that told whether or not anything was getting from the eye to the brain. We were looking for the lowest level wave form - P100 wave form. There was no wave form present in either eye. What does this mean? If the P100 wave form is not present, there is no vision. However, for the test to be accurate, the front of the eye has to be in tact and in good shape. Well, Carver's right eye looks really good and should be a good eye - retina is fully attached with minimal scar tissue, the lens is clear, and the cornea is clear. The problem with this eye is a bad optic nerve. Our last report from Michigan mentioned a pallor optic nerve - meaning a damaged optic nerve. It is hard to tell how much damage is there. The VEP confirmed that the damage is severe enough to cause him to have no vision is this eye. Carver's left eye is not in good shape - the retina is only attached around the edges, the lens is developing a cataract, and there is a sponge behind the eye. So, the VEP on the left eye can not be validated. You need a clear path to the optic nerve in order to get a clear path to the brain. So, we can dismiss the test for now. We believe that Carver is at least seeing lights and shadows from this eye. The VEP can not confirm or deny this. We will continue to work on this eye until something changes that indicates no vision.
Monday evening Carver is going in for a sleep study. It will be nice to figure out what's going on with all of these apnea spells. The good news is that the Neurologist does not believe the apnea spells are related to anything neurological or any of the medicines that he is taking. It will take a couple of weeks to get the results of the test.
We're counting the days till CI activation #2 on May 27th!!
Kinnick's big news..... today she said bye bye! I hope this is the beginning of words.

I have been waiting for you to post the results of this test. Do you basically have to wait until he is old enough to tell you what he sees? That is easier said than done.
