Understanding Glaucoma: Causes, Symptoms, and Prevention

Glaucoma is a condition that affects the eyes’ optic nerves. Over time, glaucoma gets progressively worse due to a buildup of pressure within the eye. Having an adequate awareness of glaucoma is very important to ensuring continuous good eye health. By having a good understanding of its causes and symptoms, it becomes easier to pinpoint preventive measures, as well as the necessary treatments.

To this effect, Eye Health Centres has compiled for you some information about the causes, symptoms, preventive measures, and treatment options regarding glaucoma. You can also visit our website to learn more about our eye care and health services.


Causes of Glaucoma

The main cause of glaucoma is due to an obstruction in the channel that allows a fluid known as the aqueous humor to flow out of the eye. Such a blockage can cause this fluid to accumulate within the eye, thus causing glaucoma and impaired eye health.

Other less common causes include the following:

  • Eye injuries due to blunt trauma or chemicals

  • Severe eye infections and inflammations

  • Blocked blood vessels in the eyes

  • Rare side effect of corrective eye surgeries


Risk Factors of Glaucoma

There are also risk factors that may increase a person's likelihood of developing this disease, hence the need for proper glaucoma awareness. People who are at a higher risk include the following:

  • Adults over the age of 40

  • People with a family history of glaucoma

  • Patients suffering from pre-existing conditions such as diabetes, high blood pressure, heart disease, sickle cell anemia and high eye pressure, among others


Symptoms of Glaucoma

  • Blurred vision

  • Throbbing eye pain

  • Severe headaches on the same side as the affected eye

  • Nausea and vomiting

  • Eye redness

  • Halos around light sources

  • Gradual loss of side vision

  • Dilated pupil

  • Increasing loss of vision


Glaucoma Awareness and Prevention

In most cases, people suffering from glaucoma have no early telltale symptoms or pain. Such symptoms won’t usually develop until later stages of the disease, increasing the risk to the patient’s eye health. This is why it is so important to have proper glaucoma awareness. Also, by visiting your eye doctor regularly, you will be able to take the right steps to prevent the occurrence of glaucoma and reduce the risk of long-term vision loss.
