Glaucoma is an eye illness that can cause optic nerve damage. The optic nerve transfers visual information from your eyes to your brain. Glaucoma San Antonio is typically, but not always, caused by unusually high intraocular pressure. The increasing pressure can damage optic nerve tissue over time, resulting in vision loss or possibly blindness. Furthermore, if detected early, you can be able to avoid further vision loss.
Causes of glaucoma
The back of your eye constantly produces a clear fluid known as aqueous humor. This fluid fills the front region of your eye when it is made. It then exits your eye via channels in your cornea and iris. If these channels become completely or partially blocked, the natural pressure in your eye, known as intraocular pressure (IOP), may rise. Your optic nerve may be injured if your IOP increases. As nerve damage continues, you may lose vision in one eye. It is not always clear what causes increased ocular pressure. Doctors believe one or more of the following variables may be involved:
- Blocked or hindered drainage in the eye.
- Dilating eye drops.
- High or elevated blood pressure.
- Medications, like corticosteroids.
- Poor or decreased blood flow to the optic nerve.
How to diagnose glaucoma
Your ophthalmologist will want to do a thorough eye examination to detect glaucoma. They will look for indicators of degeneration, such as nerve tissue loss. They may also employ one or more of the tests and procedures listed below:
- Comprehensive medical history: Your physician will want to hear about your symptoms and whether you have a personal or family history of glaucoma. They will also request a general health examination to see if you have any other health issues affecting your eye health, such as diabetes or high blood pressure.
- Tonometry examination: This test examines the inside pressure of your eye.
- Pachymetry examination: People with thin corneas are more likely to acquire glaucoma. A pachymetry exam can notify your specialist if your corneas are thinner than typical.
- Perimetry exam: This examination, also called a visual field test, can inform your doctor if you have glaucoma by testing your peripheral or side vision and central vision.
- Monitoring the optic nerve: If your doctor wishes to watch for subtle changes in your optic nerve, they may take images of it to compare side by side over time.
What to expect if you have glaucoma
Blindness is an uncommon consequence of glaucoma when discovered early. Conversely, glaucoma is a chronic and progressive illness that frequently results in some degree of visual loss over time. The earlier you detect glaucoma and begin treatment, the greater your chances of preserving your eyesight. Treatments can delay disease development and prevent eyesight loss. Additionally, regular eye examinations are vital if you are at high risk for glaucoma.
While there is no cure for glaucoma, therapies can manage eye pressure and prevent visual loss. Eye examinations can detect the condition early and help you keep your sight. If you are at high risk for glaucoma, ask your eye doctor how frequently you should be screened. If you have glaucoma, you must take daily eyedrops as directed. Inquire with your provider about laser treatments and surgical possibilities. You may prevent glaucoma from progressing and suffering permanent vision loss or blindness by taking regular care.
