Is there a natural remedy to treat glaucoma rather than taking the medication prescribed?

I do not want to take the eye drops the Ophthalmologist prescribed. First of all it's too expensive. Even the co-pay is $100.00 a month. I can't afford it. And second of all I want to avoid the dark pigmentation around the eyelids that's caused due to the drops. This reason by the way is the least of all my concerns. Is there any type of alternative medicine that will do the same as the eye drops so that I can avoid using them? Thanks!
