we all must quit smoking and make a law which prohibits all type of smoking or taking any drug etc.....
Hi,
I assume that they also did a fundoscopic exam and looked at the back of your eyes for bleeding or lack of blood flow(if not, they should do this right away). Other concerns would be a pituitary mass which can press on the optic nerve and cause some defects in vision. Be sure to follow up with your doctor about this soon, and see and ophthalmologist as well. As it seems to be progressing, you should not wait too long between appointments to discover and treat the cause.
Take care.
