Recently diagnosed w/open angle glaucoma and being treated w/ 1 drop. In general, how long is it before you know if glaucoma is under control?

Recently diagnosed w/open angle glaucoma and being treated w/ 1 drop. In general, how long is it before you know if glaucoma is under control?

Quickly: Presumably you had elevated pressure in your eye. The drop given should lower the pressure within a week. Your ophthalmologist (you are seeing an ophthalmologist for such a diagnosis?) will have you come back soon to see if the eye pressure responded to normal with your drop. ...Read more

Glaucoma (Definition)

A condition that causes damage to your eye's optic nerve and gets worse over time. It's often linked to a buildup of pressure inside your eye. Without treatment, glaucoma can cause total permanent blindness ...Read more

How does open-angle glaucoma damage the optic nerve?

How does open-angle glaucoma damage the optic nerve?

Slowly over time: Typically open angle glaucoma causes loss of ganglion cells with progressive thinning of the retinal nerve fiber layer faster than age-related loss slowly over time (thus generally asymptomatic), eventually leading to an enlarged optic nerve cup seen on eye exam. The optic nerve appears pale with loss of tissue and remodeled laminar changes. ...Read more

What are the most common symptoms of open angle glaucoma?

What are the most common symptoms of open angle glaucoma?

No symptoms: One of the things about open angle glaucoma is that the peripheral vision loss "sneaks up" on folks. There are no symptoms, and the sign of peripheral vision loss is not noticeable until the vision loss is advanced. If there is a suspicion or family history, have a proper evaluation by an eye doctor. ...Read more

In monitoring open angle glaucoma, if oct test results taken 1 yr. Apart are different, can it mean glaucoma isn't stable? No change in visual field.

Open angle glaucoma: By definition will diminish your retinal nerve fiber layer (rnfl) over time if not well controlled. Serial rnfl scans are highly sensitive and can detect small changes prior to a formal visual field test demonstrates changes. Questions if loss is occurring can be answered by looking at serial scans of the rnfl over time and looking for trends. So, yes, it may not be stable and requires follow up. ...Read more

Have open angle glaucoma in early stage. Can it affect night driving? I seem to not be able to see curbs, lines & turning lanes as well as I should.

Have open angle glaucoma in early stage. Can it affect night driving? I seem to not be able to see curbs, lines & turning lanes as well as I should.

Glaucoma affects: Your peripheral vision, your symptoms are due to a slight amount of nearsightedness that occurs at night, "night myopia", this happens to everyone and is not related to glaucoma. Glaucoma vision deficits come with uncontrolled or advanced glaucoma, not in the early stages. ...Read more

How many times can slt be repeated to treat an eye with early stage open angle glaucoma? Need pressure lowered by 30%.

How many times can slt be repeated to treat an eye with early stage open angle glaucoma? Need pressure lowered by 30%.

Depends: If a reasonable response to slt has been determined (15 to 30% reduction in iop) then I consider repeating it if the duration of effect is at least over a year, but preferably over 2-3 years. If the effect falls off rapidly, I don't repeat it. I move on to other treatment modalities if glaucomatous progression is noted or if the target range of iop has not been achieved. ...Read more

Treated w/laser glaucoma open angle, unsuccessful. Now on Xalatan generic and timoptic (timolol). Is there any new treatment? 83 y.O. Male w/ open angle glaucoma; 40 years chronicity. Reccomendation?

Treated w/laser glaucoma open angle, unsuccessful. Now on Xalatan generic and timoptic (timolol). Is there any new treatment? 83 y.O. Male w/ open angle glaucoma; 40 years chronicity. Reccomendation?

Yes: This is a very good but complicated question. You have not given me nearly enough information to render an opinion. If you are hoping to discontinue your eye drops there are several newer surgical procedures which might work. Talk to your eye doctor about these options. ...Read more

Any new treatment for open angle glaucoma?

Yes: The latest surgical treatment approved for open angle glaucoma and cataract is called istent. In this procedure, the surgeon inserts a tiny stent inside the eye to bypass a portion of the eye's natural drainage system. New drugs for glaucoma are close to approval, but not available yet. ...Read more

Why is it that in some patients w/open angle glaucoma, the treatments aren't successful in slowing nerve damage and preventing substantial field loss?

Why is it that in some patients w/open angle glaucoma, the treatments aren't successful in slowing nerve damage and preventing substantial field loss?

Frustrating: Some individuals just don't quite respond well enough to conventional treatment strategies. This implies that the iop-reduction philosophy is not always the only factor beneficial to stabilizing the disease. Other factors may be genetic, blood flow, pressure-perfusion imbalances. This is when off label approaches may be attempted: ca2+ channel blockers, statins, ginkgo, limit activity that inc iop. ...Read more

Can you cure an open angle glaucoma by surgery?

Can you cure an open angle glaucoma by surgery?

Stabilizable: Unfortunately, we don't have a surgical/medical cure for glaucoma. The current treatments are very effective and provide a tremendous stabilizing influence on glaucomatous disease. Glaucoma requires chronic and diligent life long care to assure that visual function remains as high as possible throughout life. I remain optimistic about medical/surgical research on better treatment strategies. ...Read more

I've got "open angle glaucoma" what is it? Is it heriditary?

Optic nerve damage: Open angle glaucoma is a group of disorders in which there is characteristic and progressive damage to the optic nerve. This results in loss of peripheral vision and can cause blindness. Glaucoma has numerous causes, some of which are genetic and not all of which are fully understood. While having family members with glaucoma increases your risk of getting glaucoma, it does not guarantee it. ...Read more

Who is at risk for open-angle glaucoma?

Risk factors are...: Family/ethnicity are important. Those at highest risk for open-angle glaucoma have a sibling with glaucoma; or a parent. African-americans and hispanics are at higher risk than caucasians. Asians have a higher risk for angle-closure disease (e.g., chinese); others are at for risk low-pressure glaucoma (japanese.)

other risks include a serious eye injury, or long exposure to Prednisone therapy. ...Read more

What is open-angle glaucoma?

Open angle glaucoma: This is the most common type of glaucoma in which the drains of the eye interior gradually become obstructed (like plumbing obstruction in your house) leading to elevation of the interior eye pressure. This squeezes the nerves and blood vessels at the back of the eye causing gradual loss of vision over time. Treatment (drops, laser, surgery) will lower pressure and protect the eye. ...Read more

How long can open angle glaucoma go untreated?

How long can open angle glaucoma go untreated?

Never good: Unfortunately, undiagnosed glaucomatous disease & failure to adhere to recommended prescribed treatments for those diagnosed are two of the biggest issues of managing an otherwise very treatable & stabilizable Disease. The best advice is to have a comprehensive eye exam before age 40, particularly if you are in a a high risk group. ...Read more
