When should you start glaucoma treatment?
If glaucoma is present, patients with intraocular pressure above 14 mmHg should be treated, as in such cases there is always a "pressure risk factor".
What happens after a glaucoma diagnosis?
The increased pressure in your eye, called intraocular pressure, can damage your optic nerve, which sends images to your brain. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years. Most people with glaucoma have no early symptoms or pain.
Is glaucoma treatable if caught early?
There is no cure (yet) for glaucoma, but if it's caught early, you can preserve your vision and prevent vision loss. Taking action to preserve your vision health is key.
What is the treatment for early stage glaucoma?
The treatment options for early glaucoma have expanded in recent years and fall into three categories: medications, laser, and incisional surgery. Medications or laser are both considered first-line treatments. It is not imperative that you start with medications and then proceed to laser treatment.
How quickly does glaucoma progress?
Glaucoma is a slowly progressing problem. On an average, untreated Glaucoma takes around 10-15 years to advance from early damage to total blindness. With an IOP (Intraocular Pressure) of 21-25 mmHg it takes 15 yrs to progress, an IOP of 25-30 mmHg around seven years and pressure more than 30 mmHg takes three years.
Should I be worried if I have glaucoma?
While anyone can have glaucoma, adults are more likely to develop it. There are no warning signs for most types of glaucoma, which is why it's something to worry about. The effects of glaucoma can be so insignificant that you might not notice any changes to your vision.
What is considered early stage of glaucoma?
Loss of peripheral or side vision: This is usually the first sign of glaucoma. Seeing halos around lights: If you see rainbow-colored circles around lights or are unusually sensitive to light, it could be a sign of glaucoma. Vision loss: Especially if it happens suddenly.
Can you stop glaucoma from progressing?
Glaucoma cannot be cured, but you can stop it from progressing. It usually develops slowly and can take 15 years for untreated early-onset glaucoma to develop into blindness. However, if the pressure in the eye is high, the disease is likely to develop more rapidly.
What is early stage of glaucoma?
Initial symptoms of closed-angle glaucoma include sudden severe eye pain, blurred vision, bright halos appearing around objects, eye redness, or tenderness. To diagnose this type of glaucoma, an ophthalmologist will examine your eyes, ask questions about your condition, and measure your eye pressure.
What is considered dangerously high eye pressure?
Most eye doctors treat if pressures are consistently higher than 28-30 mm Hg because of the high risk of optic nerve damage.

Is intraocular pressure normal for glaucoma?
Glaucomatous changes in the optic nerve may arise even when the intraocular pressure is within normal limits (normal-pressure glaucoma). Among persons of European ancestry, the intraocular pressure is normal in 30% of all cases of glaucoma (10), with regional variation in prevalence. This disorder is apparently caused by an intraocular pressure ...
What causes glaucoma in the eye?
Glaucoma is a common condition that is usually caused by a fluid build-up in the front part of the eye, which increases pressure within the eye.

For eye drop medications, the positives include the following: They are an effective treatment option. When one of the first-line medications are used, eye pressure can be lowered by 20-35 percent. The drugs are safe and well tolerated in a large proportion of patients. Negative factors to consider include:
Can you start eye drops with laser?
If you decide to start with medications, but find that you are missing doses or have intolerable side effects, you can opt for the laser at a later date. Moreover, while the laser is not reversible, if it turns out to be ineffective you can always start eye drops later.
Is laser eye surgery a cure?
The laser procedure is not a “cure,” and the effect does wear off over time. There are potential side effects from the procedure, including an eye pressure spike around the time of the procedure. Your ophthalmologist will ask you to wait after the procedure so that you can be checked for this potential complication.
Does cataract surgery lower eye pressure?
Indeed, in some patients, cataract surgery alone may even lower eye pressure. However, by combining cataract surgery with MIGS, the eye pressure typically lowers to approximately 15 mmHg (millimeters of mercury) with the need for fewer eye drops.

Even with treatment, about 15 percent of the time glaucoma can lead to blindness in at least one eye over a period of 20 years.
What happens if your eye drainage angle is blocked?
If the drainage angle in your eye gets blocked, the aqueous humor fluid level rises. This puts pressure on the optic nerve. Over time, this is what causes vision loss and eventual blindness. Glaucoma is a group of eye diseases that is caused by damage to the optic nerve related to high intraocular eye pressure (IOP).

Risk Factors for Developing Glaucoma 1 Age: Glaucoma is most common in Americans over age 60. 2 Race: It is more common in African American, Asian, and Hispanic individuals over age 40. 3 Family history: Glaucoma has a genetic component. 4 Medical/biological conditions: Some medical conditions, like diabetes and high blood pressure, increase the risk for glaucoma. Thin corneas and chronic eye inflammation also increase the risk. 5 Trauma: An injury to the eye can increase eye pressure. 6 Medications: Prolonged use of corticosteroids increases the likelihood of glaucoma.
Why is it important to have regular eye exams?
This is why it is important to undergo regular eye exams to test your IOP and make sure things are within the normal range. Once you have been diagnosed with glaucoma, vision loss progresses slowly, particularly if you begin treatment in the early stages of the condition.
What is the function of the optic nerve?
This can push on the optic nerve at the back of the eye. The optic nerve is what sends information to your brain about what you are seeing. Your optic nerve is made up of many small nerve fibers, and high fluid pressure can kill them. As the nerve fibers die, your vision can be impaired.
