Glaucoma Care

What is glaucoma?

Glaucoma is a group of diseases that cause progressive and irreversible damage the optic nerve (the bundle of nerve fibers that carries information from the eye to the brain). Glaucoma is the second leading cause of blindness and is known as the “silent thief of sight” because symptoms most often don't occur until considerable damage is done.

Fortunately, glaucoma is highly treatable if detected early. The key to preventing serious vision loss or blindness from glaucoma is annual, dilated eye examination. Schedule an annual eye exam with Hauser-Ross to have our team assess your vision and recommend next steps.

What are my treatment options?

The effects of glaucoma are permanent, but with early treatment, the loss of vision can be minimized. In some patients, damage occurs very slowly and treatment may not be necessary. However, most patients do require treatment, such as eye drops, to prevent or delay loss of vision.

Glaucoma Frequently Asked Questions

Am I at risk of getting Glaucoma?
Everyone is at risk for developing Glaucoma, but certain groups have a higher risk, including:
  • African-Americans – Glaucoma is 6 to 8 times more common than in Caucasians
  • Hispanic Americans in older age groups
  • Eye injury patients
  • All individuals who are over the age of 60
  • Diabetics or those with high blood pressure
  • Those with a family history of Glaucoma
  • Steroid users – recent evidence links Glaucoma and high steroid use
  • People with high myopia (severe near-sightedness)
Your best defense is to have regular eye exams and a Glaucoma screening test, especially if you fall into a high risk group.
How common is Glaucoma?
Worldwide, Glaucoma is the leading cause of irreversible blindness. In fact, as many as 6 million individuals are blind in both eyes from this disease. In the United States alone, according to one estimate, over 3 million people have Glaucoma. As many as half of the individuals with Glaucoma, however, may not know that they have the disease. The reason they are unaware is that Glaucoma initially causes no symptoms, and the loss of vision on the side (periphery) is hardly noticeable.
What causes Glaucoma?
Glaucoma is usually caused by an increase of fluid pressure in the eye. The front part of the eye contains clear, nourishing fluid called aqueous which constantly circulates through the eye. Normally, this fluid leaves the eye through a drainage system and returns to the blood stream.

Glaucoma occurs from an overproduction of fluid or when the drainage system becomes blocked, causing fluid pressure to increase. The high pressure causes damage to the optic nerve, resulting in permanent vision loss. The exact reason the fluid system in the eye stops functioning properly is not completely understood. However, research is constantly being done to further our understanding of Glaucoma.
What are the signs and symptoms of Glaucoma?
Glaucoma can progress slowly and those who present with the disease may already have severe vision loss. Consequently, your best defense is to have regular eye exams and a glaucoma screening test, especially if you fall into a high risk group.


    Open angle glaucoma – the most common form of the disease, has no initial symptoms. It isn’t even evident until the optic nerve becomes damaged and peripheral (side) vision is lost through the slow build up of pressure in the eyes.

    Acute closed-angle glaucoma happens more suddenly when blockage occurs in the normal flow of eye fluid between the iris and the lens. This type of glaucoma is a medical emergency and if not treated immediately, blindness could occur in one to two days. Acute closed-angle glaucoma symptoms include:
    • Severe pain
    • Nausea
    • Vomiting
    • Blurred vision
    • Seeing halos around lights
    Another type of glaucoma is called chronic closed-angle glaucoma. This type is similar to open-angle glaucoma, in that it progresses more slowly and can damage the optic nerve without prior symptoms.
