Glaucoma or Blue Water is a disease in which the optic nerve is damaged by factors such as increased intraocular pressure. Since the optic nerve is responsible for transmitting vision information to the brain, damage to it gradually causes visual field defects, and if the disease is not treated and progressed, it can ultimately lead to complete blindness. The disease has several types: congenital glaucoma, open- angle glaucoma, and closed -angle glaucoma. Glaucoma Subspecialty Clinic of Noor Eye Hospital offers theses services with experienced ophthalmologists and the use of advanced diagnostic and therapeutic tools, including the latest OCT imaging devices, as well as laser and surgical treatments.
