Acute Glaucoma
Acute glaucoma comprises slightly less than 5% of all glaucoma cases. However, it is important to recognize the symptoms
since they come on very suddenly and are associated with extreme and rapid loss of vision, redness and pain. The aqueous
humor drains into Schlem's canal, which is located in the area of the eye called the anterior chamber angle. This angle can
be examined only with a special lens utilizing a technique called gonioscopy. When this angle suddenly closes off and blocks
the flow of fluid, the pressure rises suddenly, and if left untreated the rapid loss of vision could become a permanent
condition. Other important tests are visual fields and measurement of the retinal nerve fiber layer, and the contour of the
optic nerve.
The pressure needs to be relieved as quickly as possible, since any vision loss will most likely be permanent. It is usually
treated medically, followed as soon as possible with either laser or regular surgery.
