My mom, 79yrs old, had a benign meningioma surgically removed from her left frontal lobe this past Tuesday 3/6/07. The surgery was very successful. My mom has glaucoma and the doctors have her on steroids and Dilantin to prevent swelling and seizures post surgically. How dangerous is that for the glaucoma, since she should be on these meds for a while? Also since she went on these medications before surgery I noticed that her balance has been compromised as well as her speech very slow. These occurances were not like this before she started these meds. Can you help and answer these questions for me? Thank you
