As the second most common cause of blindness world wide (depending on the race), glaucoma comprises a very severe disease. The retinal neuroepithelium, that is the tissue which receives and transports all the visual stimuli to the brain, is progressively destroyed, without being perceived from the patient even in the advanced stages.
The most common form of glaucoma, in the Caucasians of Europe, is Chronic Open Angle Glaucoma.
Nowadays, the advances in pharmaceutical technology has led to the establishment of the medical treatment of glaucoma in the form of eye drops, with very simple dosage schemes. In some cases, the patient undergoes additional therapies, with special Laser or/and implantation of drainage valves which drain the aqueous humor from the anterior chamber.
In the resistant forms of the disease as well as in some special cases of other forms of glaucoma, the patients undergo several forms of surgical therapies, commonly, trabeculectomy.
