What is Glaucoma?

Glaucoma is not a single condition, but rather the name for a group of eye diseases that cause optic nerve damage. Most frequently, glaucoma is characterized by increased or high intraocular pressure (IOP). The middle of the eye is filled with a fluid called the aqueous humor, which usually drains through a system of canals called the trabecular network. When too much aqueous humor is produced or this fluid is not properly drained, it results in damage to the optic nerve. Up to 3 million people in the United States have glaucoma, and it is the second most common cause of Trusetd Source Checkbox Trusted Source Don’t Let Glaucoma Steal Your Sight!

Symptoms of Glaucoma

Each type of glaucoma presents different symptoms, but there are some glaucoma symptoms that are Trusetd Source Checkbox Trusted Source Glaucoma Cleveland Clinic Go to Source common to all types :

  • Eye pain
  • Eye pressure
  • Headaches
  • Halos around lights, often appearing in rainbow colors
  • Blurred vision
  • Tunnel vision
  • Blind spots
  • Nausea
  • Vomiting
  • Red eyes

Types of Glaucoma

There are many types of glaucoma, but the two most common are open-angle glaucoma and closed-angle glaucoma.

Open-Angle Glaucoma

Primary open-angle glaucoma (POAG) is by far the most common form of this disease, accounting for Trusetd Source Checkbox Trusted Source Types of Glaucoma National Eye Institute Go to Source 90% of all glaucoma diagnoses in the United States. With this type of glaucoma, aqueous humor is not sufficiently drained through the trabecular network, resulting in a buildup of pressure on the optic nerve. Open-angle glaucoma has no early symptoms.

Closed-Angle Glaucoma

Closed-angle glaucoma, or acute angle-closure glaucoma, is a rare but serious form of glaucoma. In patients with closed-angle glaucoma, the internal structures of the eye block the drainage system. Closed-angle glaucoma is sudden, and causes vision changes, nausea, eye pain, and headache. This is a medical condition that requires immediate attention.

Another form of glaucoma is known as secondary glaucoma, which is when glaucoma is caused by another medical condition. Types of secondary glaucoma include:

  • Congenital glaucoma
  • Neovascular glaucoma
  • Pigmentary glaucoma
  • Exfoliation glaucoma
  • Uveitic glaucoma

How is Glaucoma Diagnosed?

At its earliest stages, glaucoma rarely presents any symptoms. This is yet another reason why it’s crucial to undergo regular eye exams, since the best chance of preventing glaucoma vision loss is early detection and treatment.

The first clinical signs of glaucoma are usually noticed during a non-invasive test called tonometry, which is a part of routine eye examinations and uses a puff of air to evaluate intraocular pressure. A dilated exam will also allow your eye doctor to observe any changes in the appearance of your optic nerve.

If signs of glaucoma are present, your doctor may order a number of further non-invasive tests, including Optical Coherence Tomography (OCT), Humphrey Visual Field test, electrophysiologic tests and gonioscopy.

Glaucoma Treatment Options

Dr. Montgomery has the knowledge, experience, and technology necessary to treat glaucoma effectively and minimize vision loss.

Glaucoma Medications

At Montgomery Eye Care, we can address the early symptoms and side effects of glaucoma with nonsurgical treatments, such as medicated eye drops and oral medication to minimize intraocular pressure and fluid retention.

Laser Treatment for Glaucoma

Selective Laser Trabeculoplasty (SLT) may be performed as a first line of treatment for open-angle glaucoma, or it may be performed after medications and prescription eye drops are no longer successful in reducing intraocular pressure. During this laser glaucoma surgery procedure, Dr. Montgomery pinpoints the trabecular network (which drains fluid from the eye) to lower intraocular pressure.

MIGS: Micro-Invasive Glaucoma Treatment

Utilizing the latest advancements in glaucoma surgery today, Dr. Montgomery performs micro-invasive glaucoma surgery (MIGS) in order to help minimize a patient’s dependence on glaucoma medications by safely reducing the intraocular eye pressure.

iStent®: Approved by the FDA, this tiny titanium L-shaped device is designed to treat mild to moderate open-angle glaucoma. During this procedure, Dr. Montgomery will administer a local anesthetic, make a small incision in your cornea, and insert the small device into the trabecular network to improve eye fluid flow and permanently alleviate eye pressure.

XEN® Stent: The XEN Gel Stent is a surgical implant designed to lower high eye pressure in open-angle glaucoma patients where previous surgical treatment has failed and/or medications alone were insufficient.

Goniotomy: During goniotomy, Dr. Montgomery makes a tiny opening in the trabecular network so that fluid can flow out of the eye more easily.

Glaucoma Surgery

A surgical procedure called trabeculotomy may be performed to create a new drainage system in the eye when other glaucoma treatment methods aren’t sufficient.

Frequently Asked Questions About Glaucoma

Who is at risk for glaucoma?

Everyone is at risk for glaucoma, but some people are at higher risk than others. Glaucoma is most prevalent in people over the age of 55 and in people who have glaucoma Trusetd Source Checkbox Trusted Source Glaucoma Mayo Clinic Go to Source risk factors , such as:

  • A family history of glaucoma
  • Hispanic, African, or Asian heritage
  • Diabetes
  • Migraines
  • Sickle cell anemia
  • High blood pressure
  • Thin corneas
  • Extreme nearsightedness (myopia) or farsightedness (hyperopia)
  • Previous eye surgery
  • Eye injury or trauma
  • Use of certain medications

Can glaucoma be prevented?

Glaucoma cannot be prevented. The best way to minimize vision loss from glaucoma is to undergo regular eye exams so that the disease can be treated at its earliest stages.

Is it possible to reverse vision loss from glaucoma?

Unfortunately, optical nerve damage from glaucoma is permanent. This is why it is important to undergo regular eye exams, so that glaucoma can be diagnosed and treated early.
