Recommendation for a 93 year old woman who has severe glaucoma? Still has 20/20 vision and healthy.

Quite frankly, with current medication and her age, I would not recommend cannabis in a person this age. Though cannabis has been shown to help in glaucoma, most of the time the effect lasts only a few hours so cannabis needs to be consumed often. There are many eye medications that last a good deal longer than that and are probably more effective.
