I go to Dr. Kastl because Tulane Opthamology has the glucoma pen. This pen is used to test glucoma by just touching your eye after numbing drops have been placed in your eye. Since I have trouble leaning close enough in the glucoma machine for my eyes to be tested, this is a perfect solution. Dr. Kastl and his nurses are nice and informed. However, I hate his interns. The interns tend to treat the patients like guinea pigs. Being in a wheelchair, the intern seemed thrilled she gotta to see "a strange case". She tried to tell me I was going blind because she was too ignorant to understand that my physical condition had nothing whatsoever to do with my eye sight. I had to tell her she was wrong and get out. If the interns wouldn't exist there, it'd be perfect.
