Hi Claudia (that’s my wife’s name too)
A good eye doc can often tell by looking at you if there is eye involvement. One of the main indicators according to my first doc is glaucoma when you look up. Mine skyrocketed when my eyes went up. Aother thing that showed up (I hadn’t realized it) when the nerve is involved is degradation of color vision, so it is good to get that checked. If your eyes are dry he can do a “Shermers” which checks for the rate of tearing. Basically they hang a little rag off your eyelid and see how fast it wets. What a thrill.
Good luck at the doc’s!
