Glaucoma is a very serious eye disease. It’s the leading cause of irreversible blindness worldwide. Patients with glaucoma will need to see their Optometrist in Houston more often than the average patient. To determine if a patient has glaucoma, an experienced optometrist like ours at West U Vision will need to perform several tests.
Typically, vision loss from Glaucoma is due to high pressure in the eye. This is a result of the problems with draining fluid in the eye; it can’t get out very well. Glaucoma is a sneaky disease because it remains hidden until it has advanced. The central vision doesn’t go until the very late stages of the diseases and until then it could go undetected due to unnoticeable symptoms or complete lack of symptoms. Early diagnosis of glaucoma, is extremely important because glaucoma causes irreversible blindness. Once vision is lost, it cannot be regained. Determining is a patient has glaucoma requires several visits to the Optometrist in Houston because many tests need to be performed to determine if a patient has glaucoma. The tests that are usually performed to diagnose glaucoma include: intraocular pressure test, an optic nerve exam, a visual field test to see if there is loss of peripheral vision, and gonioscopy test (angle exam). Intraocular pressure can be tested by using an air puff test or the Gold Standard that ophthalmologists uses; which is involves a split lamp. Once the patient places his head in the slit lamp, a probe comes to the eye. After a drop is put into the patient’s eye, the probe touches the eye and counterbalances the pressure in the eye. The eye doctor looks at the optic nerve to see if it’s healthy or if there are signs of glaucoma. The gonioscopy distinguishes between the two types of glaucoma: open angle and closed angle.
