Many serious threats to the health of your eyes and your vision come without warning, silently damaging the delicate tissues and structures of your eyes. You may not realize something is wrong until the eye disease has reached an advanced stage when treatment does not work quite as well. Glaucoma is one such disease, quietly robbing people of their vision.
Glaucoma develops as the result of damage to the optic nerve. Light carries information about images into the eye. This light strikes the light-sensitive tissue lining the interior wall at the back of the eye. The information travels from the retina through the optic nerve to the brain for processing. Damage to the optic nerve prevents the information from traveling from the retina to the brain, resulting in poor vision.
Fluid helps the eye keep its shape. Too much fluid, however, causes excessive pressure inside your eye and this high-pressure damages the optic nerve.
One part of the eye produces this fluid, while another part of the eye drains the liquid. The fluid drains out through angled canals known as trabecular meshwork.
In most cases of glaucoma, damage to the optic nerve develops when the eye does not regulate its fluid pressure correctly. The eye may produce too much fluid or have trouble draining it.
Vision loss usually starts with peripheral vision, which is what you can see out of the sides of your eyes when looking straight ahead. Because you do not rely on peripheral vision as much as you do straight-ahead vision, you may not notice changes in your vision before extensive damage occurs.
There are several types of glaucoma, categorized according to their causes. The most common type of glaucoma, wide-angle glaucoma, is the result of partial blockages in the trabecular meshwork that slowly block the draining of fluid from the eye. Narrow-angle glaucoma is the result of a sudden and total blockage of the eye’s drainage system.
Glaucoma is a progressive and irreversible condition, which means it gets worse over time and treatment does not restore lost vision. Treatment can slow the rate of progression, fortunately, and even halt vision loss. To be effective, however, treatment must start as early as possible. Our eye doctors at Space Center Eye Associates, Dr. Manuel or Dr. Robinson, provide potentially sight-saving glaucoma diagnosis and treatment services.
Glaucoma Diagnosis and Treatment from Your Houston Optometrist
Patients know when they need emergency treatment for narrow-angle glaucoma – sudden onset of eye pain prompts them to seek care right away. Patients do not always know when they have wide-angle glaucoma, though – only regular eye exams can reveal that.
During a routine eye exam, our optometrist performs tonometry to measure the pressure inside your eye. If your pressure is higher than the normal range, our optometrist will view your optic nerve under magnification and check your peripheral vision. We can perform additional testing and treatment in our Space Eye Center Associates office.
