Update

My youngest, Emily, of whom I've written about many times here, is the reason for my extended absence here and extended time away from Montana.

A couple months ago, she suddenly started having persistent vision disturbances, she describes it as a overlay of static-type as from an old tv, over everything she sees, and a few other vision issues. A ophthalmologist confirmed her eyes were normal. That leaves brain.  After a negative CT, she had an MRI which showed a meningnoma near the optic center, and the carotid artery. This is the most common type of brain tumor. It also showed a chiari malformation, which can also affect vision, among other things. Another possibility is a type of migraine vision issue, in her case without the headaches. It's also atypical in that it is 24/7 for the last couple months, but not unheard of. 

She's currently going through a series of appointments, second opinions, etc. Next up is a neurosurgeon. 

Pretty much that's all I know for now. She is taking it remarkably well, considering she had to drop out of university because she can't read, so she's on medical leave as a student. 

More at some other point. I still read your posts once in a while. I'm staying with the oldest, alas on the opposite side of Seattle, so I have a long commute some days. 

Take care.
