... in response to Glaucoma Symptoms

    You need to correct your opening sentence.  "There are several types of glaucoma and all of them are characterized by raised intraocular pressure."  Normal tension glaucoma sufferers have intraocular pressure in the "normal" range (less than 21).  Normal tension glaucoma is found in approximately one fourth of all glaucoma sufferers.  It would be highly misleading to suggest to people that if they have "normal" intraocular pressure, they won't develop glaucoma.
