Glaucoma is one of the leading causes of blindness in the United States today. There are two major types of glaucoma, primary open angle glaucoma and narrow angle or chronic angle closure glaucoma. We will discuss primary open angle glaucoma first. Primary open angle glaucoma is a disease of the optic nerve that if left untreated, leads to permanent vision loss. Risk factors for glaucoma include age, family history, and patients of African descent. There are other risk factors as well, but the others can only be detected through a complete eye exam.
The bad news about glaucoma is that patients often times have no symptoms until severe vision loss has occurred. It has been nicknamed “sneak thief of sight”. The reason is that glaucoma affects peripheral vision initially and central vision is typically unaffected until late in the disease process.
Therefore, glaucoma screening is very important. The Khanna Institute offices at Corona, Westlake Village and Valencia have the latest equipment needed for diagnosis of glaucoma including optic nerve photography, GDx nerve analysis, visual field exam, and corneal pachymetry.
In addition, we are proud to be able to offer selective laser trabeculoplasty (SLT) using the laser from Lumenis; as a treatment for glaucoma. The SLT is the latest technology in glaucoma lasers.
The second major type of glaucoma is narrow angle or chronic angle closure glaucoma. With this type of glaucoma, the drainage channel for fluid leaving the eye becomes progressively narrower and can completely close off, resulting in an acute glaucoma attack. Symptoms of a glaucoma attack include severe pain, photophobia, and blurry vision. An acute glaucoma attack needs to be treated immediately.
Diagnosis of narrow angle or chronic angle closure glaucoma can be done in the office using a special lens to directly observe the trabecular meshwork. We also can perform laser peripheral iridotomy with the YAG Laser; which is a treatment for narrow angle or chronic angle closure glaucoma.
