Open-angle glaucoma is the most common, occurring when the angle between the cornea and the iris is wide enough to facilitate drainage of the aqueous humour. This indicates there may be some kind of blockage or build-up in the drainage ducts.
Open-angle glaucoma develops slowly over a long period of time. This type of glaucoma is rare but dangerous. When the angle between the iris and the cornea suddenly closes, the aqueous humour becomes trapped and suddenly fills the space, causing damage to the optic nerve as the IOP rises. Acute angle-closure glaucoma happens very suddenly, and unlike the other types of glaucoma, causes intense symptoms. These symptoms include nausea, vomiting, extreme headache, extreme eye pain, excessive tears, blurred vision, and glare or halos around lights.
This type of glaucoma is a medical emergency and requires immediate attention. If you experience these symptoms, seek medical help right away. Normal tension glaucoma is also quite rare, and is easily the most baffling type of glaucoma. In normal tension cases, the angle between the iris and the cornea is wide enough to facilitate drainage, and the ducts appear to be functioning properly; the aqueous humour is flowing properly, and IOP seems to be normal, but the optic nerve still sustains damage.
Doctors continue to research this condition, but no concrete explanation has yet been found. The name glaucoma refers to a group of eye diseases which cause damage to the optic nerve. These diseases are usually associated with intraocular pressure or IOP, but not always.
The space between your cornea and your iris is filled with a fluid called the aqueous humour. The aqueous humour should always be flowing; filling and draining from the space simultaneously.
As ordered, I closed my right eye to start the eye exam. The doctor said, "Read the chart please. I was losing my field of vision and didn't know it.
That's the way glaucoma works, and why it is so important to get tested. Not until , after a game of basketball. My right eye was pulsing and there was a halo around the lights. So, I went quickly for an exam and was told, "Mr. Klose, you have severe glaucoma. They worked for a while, but by I'd lost the sight in my left eye. It was devastating at first, but I hardly notice the left eye is gone now.
I still have about half the vision in my right eye, so I can read and get around. But no more ball sports, I'm afraid. Glaucoma is a silent blinder. Fortunately, most people are never going to get it. But everyone needs to be tested. Especially if they have a family history of it—a parent or grandparent, brother or sister.
