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?

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 can I cure primary open angle glaucoma naturally by exercise or alternative safety ways please?

Not possible: There are no natural products, no natural treatment, no exercises etc. That will modify glaucoma in any way. There is effective pharmacologic and surgical treatment and you should follow the advice of your ophthalmologist for the preservation of your important vision. Naturopaths and chiropractors have no role to play at all in this condition. ...Read more

I have open angle glaucoma I have A fresh herb garden was told to be careful on herbs I use. Can you give me a list of herbs to avoid using. Thank you?

No problems: While the actual effects of most herbs is dubious, none that I am aware of will have an effect one way or the other on glaucoma. If you are in active treatment with the pressure normalized, and you feel herbs are useful in other regards, then you can use them. You might consider saving that money to make sure you can pay for your anti-glaucoma medication. ...Read more

Could u please explain what is the mechanism in the angle clossure glaucoma and open angle glaucoma.?

Elevated IOP: Angle closure glaucoma is an acute elevation of intraocular pressure secondary to mechanical blockage of the trabecular meshwork (the drainage area of the eye) by the peripheral iris. Open angle glaucoma is usually caused by a chronic elevation of intraocular pressure caused by blockage and resistance to outflow within the trabecular meshwork leading to an optic neuropathy in susceptible eyes. ...Read more

If open angle glaucoma is uncontrolled despite a reduction in pressure from 31 to 12 is it considered normal tension glaucoma.

No: Because your IOP was considerably higher than the "normal upper range", your glaucoma would be considered high tension open angle glaucoma (presumably your angles are open). Your IOP did decrease nicely, but you indicate that your disease is progressing. Despite medications, laser & incisional surgery are possibly helpful at producing a 'more' stabilizing effect.? results of ur Neuroophtho eval? ...Read more

Are there surgeries for open angle glaucoma that will stop its progression permanently?

Unlikely: It is unknown if it would stop it permanently, but probably not. What is known is that surgeries can very adequately control the damaging pressures and thereby presumably reduce or slow progression, which is a critical component to prevent permanent vision loss including blindness from poorly controlled glaucoma. ...Read more

What is reduced contrast sensitivity in vision & at what stage in open angle glaucoma can it occur?

What is reduced contrast sensitivity in vision & at what stage in open angle glaucoma can it occur?

Ability to disting-: Uish an image or object from its surrounding space is the contrast sensitivity. It is typically not measured in routine exam. Contrast sensitivity is affected by type of correction. There is a loss of contrast sensitivity at all stages of glaucoma. Some feel that the earliest loss occurs in the blue yellow spectrum. Multifocal lenses can also result in loss of contrast sensitivity. ...Read more

Early stage open angle glaucoma, on average how long does drop stabilize the disease before 2nd drop needed to control the pressure?

Time is of essence: This is a great question with a variety of meaningful responses. Clinicians may vary a bit on target iop range but the real goal is to preserve visual function as best as possible. An iop target range is initially set to be about 25-30% lower than presentation iop, a pressure that was causing optic nerve damage. Visual fields, oct, iop, and optic nerve exams aid in deciding on another med. ...Read more

I have open angle Glaucoma. Is it safe to take lexapro (escitalopram) 10mg.

Risky: Lexapro has been associated with exacerbation of glaucoma. It is unclear whether this is due to increase in serotonin or anticholinergic effects. Most antidepressants do have some anticholinergic effects which definitely can increase symptoms of glaucoma. If you need an antidepressant Wellbutrin (bupropion) would be a much safer alternative ...Read more
