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)

Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve, the nerve that carries visual information from the eye to the brain. In many cases, damage to the optic nerve is due to increased pressure in the eye, also known ...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

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

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
