Glaucoma test tomorrow

Rob's pressure test is tomorrow a.m. so I am taking a sick day to stay home with the little ones while he and K go to the specialist for the testing. The last test was in March and was good, I am hoping this one is too. I worry each time because vision is such a fragile thing. I can't imagine not being able to see. Or rather I can't imagine him not able to see. Rob has such keen eyesight and such a love for athletics. I am grateful that our regular eye doctor was so discerning that he caught the very very earliest indicators for glaucoma many years ago. But I still worry at each and every pressure check. And I am positively anal about making sure the eye drops that he must use twice daily go in on time every time.
