One of the diseases that you can treat with eye drops, is one of the diseases that you can treat with eye drops glaucoma, glaucoma. Glaucoma glaucoma also is called and is one of the most common diseases of the optic nerve. She brings a continuous loss of nerve fibers with it, which becomes visible in the optic nerve head (optic) as increasing erosion (trench). It has the typical for glaucoma Visual field failures (scotomas) resulted, which ultimately can continue up to the blindness in the eye. The most important risk factor for a disease to a glaucoma is a high intraocular pressure. According to anatomical criteria, one distinguishes between open angle glaucoma and narrow angle glaucoma, depending on the angle between the cornea back area and anterior surface of the IRIS.
The trot disgust plant, which drains the aqueous humor from the eye is located in this Chamber angle. The open angle glaucoma are the far more common form. They are mostly chronic and long unnoticed by the patient. Often, the patient noticed that Field failures in open-angle glaucoma are late because they start outside the Center and thus compensated for the losses by the other eye. The rarer narrow angle glaucoma, however, can lead to a painful attack of glaucoma. Here, within a short time, the blindness threatens if left untreated.
The glaucoma is one of the most common causes of blindness in industrialized countries as well as in developing countries. Approximately 500,000 Germans suffer from an increased intraocular pressure, and the blindness threatens ten percent of them. However, the number of unreported cases is very high. One can assume that in Germany a total of about one million people suffering from glaucoma. If typical glaucoma damage to the optic nerve, a lasting reduction of intraocular pressure must be brought about. There is damage to the optic nerve typically chronic exceeding of a critical eye pressure. This critical or target pressure varies and must be individually set first, before he then through a treatment as possible permanently lower than. The value is usually around 15 mm Hg. Only the progression of the disease can be stopped through the therapy. Existing damage, such as Visual field defects, can be again undone. Eye drops, initially as a monotherapy, so alone, and later as a combination therapy is the first step in a glaucoma Therpie. Following medicines, mostly as eye drops, a glaucoma medication related to: beta blockers such as timolol and Levobunolol; Cholinergika such as Carbachol and pilocarpine; Alpha-2-Adrenorezeptor agonists such as clonidine and Brimonidine; Carboanhydrasehemmer, either as eye drops as Brinzolamid and Dorzolamide or in tablet form as acetazolamide; and prostaglandins such as latanoprost, Travoprost and Bimatoprost Tafluprost. Beta blockers, Alpha agonists and Carboanhydrasehemmer work by reducing the production of Chamber water from the ciliary body. Prostaglandins increase the permeability of the ciliary body and promote the so-called non-conventional Drain or Uveoskleralen drain. Cholinergika open trot disgust work by contraction of the ciliary body. If the target pressure will not reach through eye drops can, must be operated.
