Glaucoma is a chronic eye disease that causes damage to the optic nerve. This damage results from an excessively high intraocular pressure. Due to the loss of optic nerve fibers, blind spots arise in the field of vision. Glaucoma is worldwide a common cause of visual impairment. The final stage of glaucoma is blindness.


The exact cause of glaucoma is not known. However, there are factors that increase the risk of glaucoma:


There are two types of glaucoma: chronic and acute. The signs and symptoms of glaucoma depend on the type of glaucoma:


The diagnosis of glaucoma is made by an ophthalmologist, using tonometry. But that’s not the only examination. The optic nerve is also examined with a special microscope. In addition, visual field measurement is carried out in order to see which parts of the field of vision are affected.


There are several treatments available for glaucoma:


The objective is to normalize intraocular pressure and prevent further damage. Therefore, lifelong treatment and checks are necessary. Early detection of glaucoma is very important. By early intervention, damage might be limited. However, damage to the optic nerve that has already occurred, is beyond repair. If glaucoma is not treated, it can lead to blindness.
