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

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

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?

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?

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

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
