Vision Setback

We recently had a vision appointment for Savannah.  Well actually it was two within two weeks.  The first appointment showed that the optic nerve does not show any further damage in the last year.  However, the visual acuity was lower, about 20/100. 

The second one was to check her glasses.  We were hoping that we just needed an adjustment on her prescription but in reality the prescription was just fine.  There was no indication of any other eye issues that would cause a vision loss, so it looks like we have just lost some vision...  I don't think it is the last time I am going to have to say that....
