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.

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).

Why should Valium not be used if I have narrow angle glaucoma?

Valium can be used. I am not aware of any connection between glaucoma and the use of valium.
Pressure can rise. Valium is in a class of drugs that the fda has listed as a contraindication because of a potential further reduction in the angle of the eye responsible for passage of the eye fluid. If that angle is already narrow, any further narrowing may result in blockage of fluid flow causing the eye pressure to build up and cause redness, pain, and glaucoma damage to the eye nerve, which can be permanent.

Define narrow angle glaucoma?

Fluid obstruction. Narrow angle glaucoma is the condition in which the lens and iris are too far forward in the eye, and when pupillary dilation occurs some of these will have obstruction of the fluid outflow tract (meshwork) causing a dangerous elevation of the eye pressure (narrow angle glaucoma or acute glaucoma) which is a medical emergency.
A type of glaucoma. Typically, a shorter eye or anteriorly rotated ciliary body with a lens that is taking up room in the anterior chamber causing a narrow spacing from the iris to the trabecular meshwork drain of the eye. There is a spectrum of open, narrow and closed.
Narrow angle highiop. Narrow angle glaucoma is a condition where the eye pressure is elevated due to mechanical blockage of the trabecular meshwork by the peripheral iris.

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.
Narrow angles. Narrow angle glaucoma is more common in persons of asian or inuit descent, females, those with family history of narrow angles or narrow angle glaucoma, far-sighted individuals, and older patients. It causes closure of the fluid drainage system of the eye and high pressures in the eyes which can cause optic nerve damage and loss of vision if not treated.

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.
None usually. Narrow angles is an anatomical condition that increases the risk for an attack on angle closure glaucoma. Laser treatment (iridotomy) is the advised treatment and can prevent an acute, painful attack that can cause severe loss of vision. Rarely, narrow angles can partially occlude, intemittently, causing headache, eye pain, and blurred vision.
