Glaucoma?

[LibertyMom]

Ok, before you say it, I know that marijuana can be used to lower intraocular pressure in people suffering from glaucoma. Other than that does anyone know of anything else that might be useful to have around if prescription meds become unavailable? My daughter takes eyedrops in both eyes a couple times a day & I do try to keep extras around, but I was sort of hoping there might be more for me to do in that area.

Thanks!

Edited to add: Just wanted to make it clear that I'm not planning on giving my daughter marijuana.
