Ninety to 95% of glaucoma cases are of the chronic open-angle type. There are no symptoms in the early stages of open-angle glaucoma. The best means of detection is by routine tonometry and ophthalmoscope inspection of the optic disk in all persons over 20 years of age. Chronic glaucoma comes on insidiously and causes slowly progressive loss of peripheral vision by interference with the blood supply of the optic nerve. The response to antiglaucoma eye drops is usually good, and surgery is seldom necessary.


Acetazolamide and other carbonic anhydrate inhibitors (e.g., dichlorphenamide) have been shown to be extremely effective in inhibiting the production of aqueous by the ciliary body. Consequently, they are most valuable as preoperative adjuncts in the treatment of acute glaucoma and in the management of secondary glaucoma. Because of their side-effects (particularly renal calculi) long-term therapy of open-angle glaucoma with such drugs is not always feasible. Epinephrine, 0.5-2%, when instilled as drops into the conjunctiva sac, lowers the intraocular pressure.

Timolol is a beta-adrenergic agent effective in lowering the intraocular pressure by decreasing aqueous production. It is available as drops containing 0.25% and 0.5%.
Pilocarpine continues to be the most widely used antiglaucoma drop. It is essential to diagnose glaucoma before significant visual loss has occurred, since visual field loss is not reversible. Tonometry, ophthalmoscope, visual field tests, and gonioscopy are the most important procedures in evaluating and treating a glaucoma patient.

Approximately 5% of cases are angle-closure glaucoma, which produces pain, injection, and blurred vision. The patient seeks treatment immediately because of the pain. Acute glaucoma is treated surgically. The surgery is preceded by intensive miotic therapy and carbonic anhydrate inhibitors over a period of hours to lower the pressure in order to minimize complications during surgery.

 Depending on which kind of Glaucoma you have the treatment will vary. Doctors may treat it with beta blockers, or with laser treatment, or a surgical procedure where they may put in a permanent drain tube.

 I'm afraid to say it is a disease of the eye that has no cure - although - it gradually happen.

People with diabetic always are the ones that have this disease due to uncontrolled high blood sugar.

Too little sugar in the blood could also affect the eyesight.
