Glaucoma
Glaucoma is the name of a group of eye diseases which damage the optic nerve. It is often caused by increased intraocular pressure (IOP). This pressure is typically the result of a malfunction or malformation of the eye’s drainage systems. Untreated, increased IOP causes permanent damage to the optic nerve and retina and the result is progressive, irreversible loss of vision. However, early detection and treatment of glaucoma can slow, or even halt its progression.
What Causes Glaucoma?
The eyes have a clear fluid called aqueous humor, (or just “aqueous”), which fills the space between the cornea and iris. Your eyes filter this fluid using a complex drainage system. The balance between the production and the drainage of aqueous is what determines intraocular pressure (IOP). For most, the IOP level is between 8 and 21. When it rises above this range, glaucoma becomes a concern.
However, in some glaucoma cases, IOP is normal. The determining diagnostic factor for glaucoma is damage to the optic nerve.
Glaucoma Symptoms
The most common type of glaucoma is a dangerous disease because it seldom causes symptoms and glaucoma warning signs are not always immediately detected. Early detection of glaucoma is important in preserving vision and can be done during routine eye examinations.
However, certain types of glaucoma do cause symptoms:
• Congenital Glaucoma Symptoms: tearing, enlarged cornea, and light sensitivity
• Angle Closure Symptoms: extreme eye pain, sudden decrease of vision, nausea/vomiting
Glaucoma Treatment
Most patients with glaucoma require only eyedrops to control the IOP. Surgery is necessary only when medical treatment cannot lower the pressure. Surgery enables fluid to drain from the eye more efficiently. Some procedures involve lasers and can be done in-office and others must be performed in an operating room.
Dr. Carter will take the necessary time to discuss your options and help you with any questions you may have. If you would like to discuss your options, please contact our eyecare office in Dallas, Texas.
