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

Narrow angle glaucoma---who gets it? What is that?

Narrow angle glaucoma---who gets it? What is that?

Serious eye problem: Angle closure is when the outflow of aqueous humor is completely blocked and the eye pressure builds up to dangerous levels potentially causing blindness sometimes within 24 hours. It is more common in asian and native american populations particularly in alaskan eskimos. ...Read more

I have narrow angle glaucoma can I take zrytec?

Yes: Zyrtec (cetirizine) will not affect this condition. If you have had this diagnosis, hopefully you have seen an ophthalmologist who can apply a curative laser treatment and take away any risk you might have. ...Read more

What are some early signs of narrow angle glaucoma?

Pain, blur: Intermittent or early angle closure may have no symptoms, or may manifest with pain, aching over the brow, blurred vision, seeing haloes around lights. Other things can also cause these symptoms, but if you are having them, they warrant evaluation with a complete exam. ...Read more

Why Valium cannot be used if you have narrow angle glaucoma?

Why Valium cannot be used if you have narrow angle glaucoma?

Valium: As muscle relaxant, it widens opening behind eye which increases pressure inside the eye which is a term for glaucoma. ...Read more

Why shouldnt Valium be used if you have narrow angle glaucoma?

Could cause pressure: Valium is a muscle relaxant which selectively affects skeletal muscle fibers more than smooth muscle fibers found in the iris and pupil. The thinking would be that if valium or diazepam relaxes the iris muscles it could trigger angle closure glaucoma -a medical emergency. I've never seen that happen to a patient on valium and if you have a laser iridotomy it will prevent this. ...Read more

Is there a drug for anxiety that I can take with narrow angle glaucoma?

Anxiety & glaucoma: Anxiety is a serious disorder. Treatment should be carefully monitored by a physician. A "quick fix" is not wise. Probably the safer group of anxiety drugs would be the beta blockers, but they are best indicated for phobias, fears and frights. They make work for a while but tend to be less effective with time. The moral is simple, your doctor can help better with a more comprehensive approach, . ...Read more

How is it that Valium should not be used if you have narrow angle glaucoma?

How is it that Valium should not be used if you have narrow angle glaucoma?

It depends: Valium belongs in a class of medications that, in theory, could precipitate an angle closure attack (as a weak anticholinergic). In practice, this is not an absolute contraindication. What is more important is to ensure that your narrow angles are managed by your ophthalmologist (either with laser+/-medication). ...Read more

What is narrow-angle glaucoma?

What is narrow-angle glaucoma?

Anatomical Proble: Angle closure glaucoma is far less common than open angle glaucoma. The pathology is based on an anatomical narrowing of the drainage site where fluid made inside the eye drains out. Think plumbing: a clogged drain backs up, and in the eye the pressure increases dramatically. Very painful and vision can be lost entirely in a few hours. High risk patients should be treated, but only if high risk. ...Read more

What is the difference between narrow-angle glaucoma vs closed-angle glaucoma?

Glaucoma: The angle is defined by the cornea and the iris. If the angle is narrow, there is less space for aqueous fluid to leave the eye through an area called the trabecular meshwork. A closed angle is completely blocked from aqueous egress. The treatment for this is a simple laser procedure. Contact your ophthalmologist if you are concerned about this condition. ...Read more

What is the difference between narrow-angle glaucoma and other types of glaucoma?

Glaucoma types: Most glaucoma is open angle - the fluid drainage space in the front is wide and the drains within it are obstructed leading to increased pressure over time. Narrow angle, mostly in hyperopes (those with eyeglass lenses that act as magnifiers), can in older folks (over 50 or so), quickly within hours mechancially block fluid flow causing an acute glaucoma attack. This is an emergency! ...Read more

Can you tell me what is the difference between narrow-angle glaucoma and closed-angle glaucoma?

Spectrum: A narrow angle vs. A closed angle is a spectrum from partially closed to completely closed as seen on gonioscopy or other angle imaging methods. A closed angle often has scarring, though it can be appositionally closed and thus still able to open. The angle status affects treatment of glaucoma, and sometimes narrow angle configuration is a precursor or risk factor for developing glaucoma. ...Read more

Can people who have narrow angle glaucoma use contact lenses?

Can people who have narrow angle glaucoma use contact lenses?

Of course: If you know you have narrow angle glaucoma, you probably have had the diagnosis made and the treatment (laser peripheral iridotomy) already administered. There is no relationship between these features and the ability to wear contacts. So if that is your wish, discuss with you ophthalmologist to get the proper design and fit. ...Read more

Why is glycopyrrolate contraindicated if narrow angle glaucoma?

Why is glycopyrrolate contraindicated if narrow angle glaucoma?

Open angles are okay: Glycopyrrolate is an anticholinergic, which has a potential effect on patients with NARROW angle glaucoma. The effects can transiently dilate the pupil, which in turn can congest the angle where the natural drainage system is. This effect can be too much in a narrow angle eye where the angle is already compromised. This can lead to acutely increased eye pressures and worsen glaucoma. Good luck! ...Read more

Is glycopyrrolate contraindicated in narrow angle glaucoma? Why?

Is glycopyrrolate contraindicated in narrow angle glaucoma? Why?

Maybe: Glycopyrrolate is an antimuscarinic agent and could make your pupils dilate. If you have an angle prone to acute angle closure, this drug could induce an attack. I am curious why you ask about this drug, as it is not something normally prescribed by any clinic doctor and commonly only used by anesthesiologists during general anesthesia. ...Read more

Why is diphenhydramine contraindicated in narrow angle glaucoma?

It can increase IOP: http://answers.yahoo.com/question/index?qid=20090328145710aa3jfbq it has anti-cholinergic properties that can cause intra-ocular pressure in the eye to increase, due to obstruction of the normal flow of fluid out of the eye. The link above explains it in more detail. ...Read more

Can people with acute narrow-angle glaucoma take xanax (alprazolam)?

Yes and no: After a thorough eye exam with gonioscopy, it my be determined by your ophthalmologist that a prophylactic laser iridotomy will free you to use medications that otherwise would be contraindicated with a narrow angle. ...Read more
