I had a very detailed talk with the neurologist about next steps. While we can't rule out a shunt issue, the visual impairment presentation is not typical of a shunt malfunction in that both pupils are equally dilated and abnormally responsive to light. Because the shunt is only in one ventricle you would expect to see a more asymmetrical presentation. Also Sprite isn't exhibiting any other typical symptoms of a shunt malfunction. We talked about other causes. It could be the history of severe hydrocephalus and seizures. It could be a brain bleed, infection etc. Sprite's temp is normal and there are no obvious signs of infection and no typical symptoms. The first step to get more info would be another MRI which may or may not help. Then depending on results if it is the shunt she would need a partial or complete revision (replacement). We have to absorb this new info and decide on the way forward for Sprite. I'm obviously cutting out a lot of details but this is the gist of it. I'm inclined to let things be and just love her until her time comes. Our family will need to get educated about supporting a visually impaired dog and she has her fur sisters to help lead the way for her. Thanks again to all of you for your amazing support!! |
