Glaucoma is an eye condition that affects the connection between the brain and the eye called the optic nerve. When damage occurs at the optic nerve, it can lead to loss of vision and in later stages blindness. To detect glaucoma, your eye care provider will perform screening tests, a thorough assessment of the optic nerve, and next steps if you are diagnosed as a glaucoma suspect or glaucoma.
Like most diseases or conditions, early detection is very important in preventing vision loss and blindness. Although there is no cure for glaucoma, your eye doctor will recommend treatment and management options to slow the process of the advancement of glaucoma.
Depending on the type of glaucoma, there are different signs/symptoms of the disease. The most common form, primary-open angle glaucoma, does not have many symptoms for the patient to readily notice. This reinforces the need for regular eye health visits with your eye doctor.
In the front of the eye, there is a liquid known as aqueous humor that is produced by a structure called the ciliary body that travels from the back of the iris (colored part of the eye) to the anterior chamber (front compartment of the eye). Although well studied, the actual process leading to glaucoma is not totally elucidated.
The most accepted theory is that the outflow of aqueous humor (fluid inside of the eye) decreases. Therefore, an increase of fluid is maintained in the same area, which causes an increase in intraocular eye pressure (level of pressure inside the eye – not related to blood pressure). When this happens, the elevated intraocular pressure damages the optic nerve (connection between the eye and the brain). Long-term, this has significant consequences for vision.
There are many treatments available depending on the patient’s diagnosis. It is important to maintain a relationship with your eye doctor to discuss the best option for you. Some of the mainstays of treatment are as follows:
Medications (eye drops): Eye drops are prescribed to reduce intraocular eye pressure. If your eye disease is worsening or changing, your eye doctor may prescribe one or more eye drops to manage your condition.
There are many specific tests completed to build a comprehensive eye health profile to show relative risk or existence of glaucoma for a patient. Some tests may include the following:
The diagnosis of glaucoma can sometimes take several tests in a short period of time or years depending on the stage of the condition. For example, a small puzzle with larger puzzle pieces may be easy to put together; however, a very complicated puzzle with small pieces may take weeks, months, or even years. Luckily, there have been many modern advances to allow your eye doctor to build a comprehensive eye health profile to make the determination whether a patient has glaucoma.
It is not uncommon for patients to inform their eye doctor that tests have been completed in the past. Or patients informing their eye doctor that all the tests were “normal” and there was no sign of glaucoma. Unfortunately, we are dynamic or ever-changing and tests may need to be updated from time to time. Please check with your eye doctor for the next best steps.
