Narrow Iridocorneal Angle
Antidepressants: Many safe for glaucoma. Note: over-the-counter and prescription medications account for 33% of acute angle-closure glaucoma. These have been reported to associated with glaucoma: Celexa, prozac, lexapro, zoloft, wellbutrin, (bupropion) and lamictal. Best to consult to give details. ...Read more
Little: These are terms used for the type of glaucoma that is caused by anatomical obstruction by the iris of the fluid outflow from the eye. Both terms are commonly used. This causes an acute attack and this is an ophthalmological emergency. You should see your ophthalmologist immediately as treatment is very effective. ...Read more
I have just been diagnosed with anatomic narrow angle. No glaucoma. What medicines should I not take?
Look on the labels: The majority of medications that list warnings about glaucoma have to do with the concern of people with narrow angles. There are components of medications, like antihistamines, that have a dilating effect on the pupil of the eye. This can congest the area where eye fluid naturally drains and cause an increase in eye pressure. Your doctor should advise you more closely on this. Good luck! ...Read more
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
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
Yes: Just need a correct corneal fitting, doesn't affect the drain of the eye. ...Read more
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
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
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
My dr says I have "narrow angle" in my eye, but there are no signs of glaucoma. What could I have?
Rarer form: This is a type of problem that occurs in older persons (usually over age 45-50 that are hyperopic (eyeglasses act like a magnifying glass) in which the iris can dilate and block the fluid outflow tracts in the angle of the eye, and the pressure can acutely rise. You are a little young form this but might have some issue in the future. A second opinion with ophthalmologist can be helpful. ...Read more
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
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
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
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 are narrow angles in my eyes? I am 63 and dr. Said I was born with this. Why was it never diagnosed before? I do not have pressure in my e
Glaucoma suspects: Narrow angle is an anatomical configuration formed by the insertion of the iris as one side and the curve or the inner cornea on the other. People who have small eyes (usu far sighted), of certain ethnicities such as chinese, vietamese, korean may HAV higher risk for sudden elevations of eye pressure resulting from this narrow angle which can lead to acute glaucoma attack and loss of vision. L. ...Read more
With narrow angle glaucoma, raised pressure causes decreased visual acuity and sometimes pain and redness. Treatment may consist of a quick laser surgery to allow the pressure to subside. An alternate treatment may be oral medicine or eye drops.
Let your eye provider help you decide when to treat. There is no magic number. It is important to keep the pressure within normal to prevent damage. ...Read more
Sinus congestion: Will not cause angle glaucoma. In patients who have narrow anterior chamber angles (which would be diagnosed by an ophthalmologist), taking medications to treat a sinus infection could lead to an angle closure glaucoma attack. If you have narrow angles, you should avoid decongestants and anti-histamines until you are told by your ophthalmologist that it's ok to use them. ...Read more
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
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
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
It can increase IOP:

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
Laser: Have you had laser peripheral iridotomy and/or goniotomy to prevent closure? The medications that can exacerbate angle closure are anything that dilates the eye, Antihistamines and decongestants; Asthma medicines; Motion sickness medicines, and some medicines used to treat depression (tricyclic antidepressants) ...Read more
