Glaucoma is caused by a number of different eye diseases, which in most cases produce increased pressure within the eye. This elevated pressure is caused by a backup of fluid in the eye. Over time, it causes damage to the optic nerve. Through early detection, diagnosis and treatment, the progression can be slowed down and vision can be preserved.
There are two main types of glaucoma:
Primary Open Angle Glaucoma (POAG)
This is the most common form of glaucoma, affecting about three million Americans. It happens when the eye’s drainage canals become clogged over time. The inner eye pressure (also called intraocular pressure or IOP) rises since the fluid cannot drain out of the eye. Most people have no symptoms and no early warning signs. If open angle glaucoma is not diagnosed and treated, it can cause a gradual loss of vision. This type of glaucoma develops slowly and sometimes without noticeable sight loss for many years. It usually responds well to medication, especially if caught early and treated.
Angle Closure Glaucoma
This type of glaucoma is also known as acute glaucoma or narrow angle glaucoma. It is not as common and is very different from open angle glaucoma because the eye pressure can drastically increase in a short amount of time. With angle closure glaucoma, the iris and cornea is not as wide and open as it should be. The outer edge of the iris bunches up over the drainage canals, when the pupil enlarges too much or too quickly (i.e. when entering a dark room). This will cause a blockage of the opening of the drainage canal. Symptoms of angle closure glaucoma may include headaches, eye pain, nausea, rainbows around lights at night, and very blurred vision.
Glaucoma surgery is sometimes necessary for uncontrolled glaucoma treated with medications. SLT/MLT laser is a special laser used especially for glaucoma patients.Please call our office if you require a second opinion or require consultation and treatment for glaucoma at 972-331-1590.
