Glaucoma symptoms and causes

The most common types of glaucoma open-angle and angle-closure,have completely different symptoms.

Symptoms of Open-Angle Glaucoma

Most people who develop open-angle glaucoma don’t experience any noticeable symptoms at first. That’s why it’s critical to have regular eye exams, so that your eye doctor can detect problems early on.

Most people who have open-angle glaucoma feel fine and do not notice a change in their vision at first because the initial loss of vision is of side or peripheral vision, and the visual acuity or sharpness of vision is maintained until late in the disease.

By the time a patient is aware of vision loss, the disease is usually quite advanced. Vision loss from glaucoma is not reversible with treatment, even with surgery.

Because open-angle glaucoma has few warning signs or symptoms before damage has occurred, it is important to see a doctor for regular eye examinations. If glaucoma is detected during an eye exam, your eye doctor can prescribe a preventative treatment to help protect your vision.

In open-angle glaucoma, the angle in your eye where the iris meets the cornea is as wide and open as it should be, but the eye’s drainage canals become clogged over time, causing an increase in internal eye pressure and subsequent damage to the optic nerve. It is the most common type of glaucoma.

 Symptoms of open-angle glaucoma are:

  • Gradual loss of peripheral vision, usually in both eyes
  • Tunnel vision in the advanced stages

Acute angle-closure glaucoma is a medical emergency and must be treated immediately or blindness could result in one or two days.

Acute angle-closure glaucoma signs and symptoms include:

  • Severe eye pain
  • Nausea and vomiting (accompanying the severe eye pain)
  • Sudden onset of visual disturbance, often in low light
  • Blurred vision
  • Halos around lights
  • Reddening of the eye

Symptoms of Chronic Angle-Closure Glaucoma

This type of glaucoma progresses more slowly and can damage the optic nerve without symptoms, similar to open-angle glaucoma.

Similarly, people with normal-tension glaucoma will not experience any symptoms until they begin to lose peripheral vision.

if you are diagnosed with glaucoma, it is important to set a regular schedule of examinations with your eye doctor to monitor your condition and make sure that your prescribed treatment is effectively maintaining a safe eye pressure.

Glaucoma and its symptoms can have a life-changing impact on anyone. Our education efforts and research updates help glaucoma patients adjust to new realities, live a full and fulfilling life, and manage symptoms, as we work to one day find a cure. Your continued financial support makes this education, and these breakthroughs, possible.

Glaucoma suspects

Some people have no signs of damage but have higher than normal eye pressure (called ocular hypertension). These patients are considered "glaucoma suspects" and have a higher risk of eventually developing glaucoma. Some people are considered glaucoma suspects even if their eye pressure is normal. For instance, their ophthalmologist may notice something different about their optic nerve. Anyone who is considered a glaucoma suspect should be carefully monitored by their ophthalmologist. An ophthalmologist can check for any changes over time and begin treatment if needed.

 

10 common question about glaucoma symptoms

1What is the first sign of glaucoma?
If the entire optic nerve is destroyed, blindness results. Other symptoms usually are related to sudden increases in IOP, particularly with acute angle-closure glaucoma, and may include blurred vision, halos around lights, severe eye pain, headache, abdominal pain, nausea, and vomiting.
2What are the main causes of glaucoma?
What Causes Glaucoma? It's the result of an intrinsic deterioration of the optic nerve, which leads to high fluid pressure on the front part of the eye. Normally, the fluid, called aqueous humor, flows out of your eye through a mesh-like channel. If this channel gets blocked, the liquid builds up.
3Can glaucoma be cured?
In general, glaucoma cannot be cured, but it can be controlled. Eye drops, pills, laser procedures, and surgical operations are used to prevent or slow further damage from occurring. With any type of glaucoma, regular eye examinations are very important to detect progression and to prevent vision loss.
4How do I know if I have glaucoma?
Dilated eye exam. After the exam, your close-up vision may remain blurred for several hours. Tonometry is the measurement of pressure inside the eye by using an instrument called a tonometer. Numbing drops may be applied to your eye for this test. A tonometer measures pressure inside the eye to detect glaucoma.
5What does glaucoma pain feel like?
The eye pain can be severe, and may cause headache, and even nausea or vomiting. In an acute angle-closure glaucoma attack, the eye pressure rises rapidly, causing pain, and also causes the cornea to become cloudy, thus patients also notice their vision has decreased.
6How do you check eye pressure?
Tonometry measures the pressure within your eye. During tonometry, eye drops are used to numb the eye. Then a doctor or technician uses a device called a tonometer to measure the inner pressure of the eye. A small amount of pressure is applied to the eye by a tiny device or by a warm puff of air.
7What are the 3 types of glaucoma?
Types of glaucoma. There are four main types of glaucoma: primary open angle glaucoma, primary angle closure glaucoma, secondary glaucoma and developmental glaucoma.
8Can glaucoma be caused by stress?
The literature suggests that stress may play a part in the precipitation of acute closed-angle glaucoma because intraocular pressure (IOP) can be affected by the emotional state of the patient. ... There is some evidence that glaucoma induction is associated with psychophysiological stress.
9Can glaucoma go away?
By the time a patient is aware of vision loss, the disease is usually quite advanced. Vision loss from glaucoma is not reversible with treatment, even with surgery. Because open-angle glaucoma has few warning signs or symptoms before damage has occurred, it is important to see a doctor for regular eye examinations.
10Is glaucoma a disability?
Social Security will grant disability benefits for glaucoma that has severely affected central and/or peripheral vision. Glaucoma is not a disease by itself, but refers to a group of optic nerve diseases that can cause blindness.
