Update on Ruffin's eyesight problem

I took Ruff to see the Ophthalmologist today and after a few tests he confirmed what I had noticed, that Ruff's eyesight has gotten worse than it was on the last visit two weeks ago. He stressed the importance of the CT Scan as being the only way to know what's going on. 

There is a new wrinkle to this problem. Since the first visit I have been taking Ruff outside on a leash to guide him. I have also been talking to him to have him follow the sound of my voice. But lately it appears he is suffering from hearing loss, as well, and either he cannot hear me or he cannot locate the direction my voice is coming from. He darts his head up and down and side to side when I talk to him. The only thing he responds to is when I touch him on his head or on his nose with a piece of food. And of course, he enjoys hugs, kisses and ear scratches. 

I mentioned the hearing problem to the doctor today and he said it may indicate the tumor is on his brain affecting both his eyesight and his hearing. 

I talked to the veterinary hospital that does the CT Scan and they said it would require sedation and take several hours from start to finish. This poses a problem for me since this place is an hour's drive away and I will need someone to stay with my wife for at least 5 hours. 

One good thing I learned today, if you can call it that, when I spoke to the place that does the CT Scans they told me that the tumors can be treated with 2 or 3 sessions of radiation instead of surgery. In spite of the cost of the CT Scan, I ruled out surgery anyway since Ruff is more than 10 years old. I didn't ask about the cost of the radiation treatment but if its anywhere near what it costs for humans it is not affordable.

Please say a prayer for Ruff. He is more important to me now than ever before.

UPDATE: 9 PM Friday.
Just found out tonight that an emergency animal clinic 20 miles away has acquired their own CT Scanner only 3 months ago. I am thrilled at the prospect of being able to have this done locally since I won't need to find anyone to come and sit with Jacqueline. Instead of a 5 hour round trip it now should take only 2 hours and I will be taking Ruff in for the scan on Tuesday afternoon.  

Prayers seem to be helping already.
