There was a story about a 62 year-old lady, who was born w/ congenital cataracts. She needed 11 surgeries on her right eye and three on her left, and had resulting problems with glaucoma. Her last surgery resulted in hemorrhaging and loss of vision.

By 1976, her intraocular pressure was out of control with all available drugs, many of which caused significant side-effects. Then she started eating and smoking cannabis (but initially had personal issues with the concept of smoking).

Her intraocular pressure went from the 50's to teens & 20's.
