hey Piff i have glaucoma as well. all it is is the nerves in the patients eyes are enlarged which in turn causes pressure, to much pressure and one can go blind. i have found that a potent sativa is best for me. i particularly like ICE, Kali Mist, or NL5 x haze. these are all sativa dominant plants and are a total head buzz. i have found that upon inhalation of a nice bowl of either of these strains, the first thing i feel is a rush of warmth and relaxation across my face. its either that im so stoned or that i can actually almost fee the prssure relieved in my eyes, might just be in my head tho. at any rate if he is not open to the marijuana idea i was prescribed an eye drop called epifrin SP? which really helps me out if i cant burn a fat one. good luck to you and your father.
