Hi,
How nice it is for you to take care of your Mom the way you do. Your Mom really raised you right .

Anyway I dont know about RSD in the eyes, but have her have them take a swab from her eye & send it in to see exactly whether or not it could be some type of obscure eye infection. The spring/summer before RSD actually went into the deep bone burning pain I had alot of trouble with my eyes. They thought I had herpes in my eye, yes a cold sore they called it. Of course I looked it up on the computer & yes that can most definitely happen. But my Opthamologist took a swab & sent it into the lab to see if something would show up so they could atleast treat it with the correct eye drop solution. Turned out I had what they called an "Obscure eye infection". Of course they did tell me at the time they took the swab that 9 times out of 10 nothing every showed up when they sent it in. I Lucked out, they treated it with the correct eye antibiotic & I finally got over it.

Good Luck,
