Understanding Glaucoma: Symptoms, Causes, Diagnosis, Treatment, and Prevention

What is Glaucoma?

Glaucoma is an eye disease that can damage the optic nerve. This nerve sends signals from your eye to your brain. Often, high eye pressure causes this damage. Over time, glaucoma can lead to vision loss or even blindness. However, early detection and treatment can help protect your sight. According to the World Health Organization, glaucoma is a leading cause of blindness worldwide.

Common Symptoms of Glaucoma

Many people with glaucoma do not notice symptoms at first. In fact, the disease often develops slowly. Still, it is important to know the warning signs. Early treatment can prevent serious vision loss. Watch for these common glaucoma symptoms:

  • Blurred vision
  • Loss of side (peripheral) vision
  • Seeing halos around lights
  • Eye pain or pressure
  • Redness in the eye
  • Nausea or vomiting (with severe eye pain)
  • If you notice any of these symptoms, see an eye specialist right away. Sometimes, glaucoma can cause sudden vision changes. Quick action can help save your sight.

    Causes and Risk Factors

    Glaucoma often happens when fluid builds up in the front part of your eye. This extra fluid increases eye pressure. Over time, high pressure can damage the optic nerve. Yet, some people get glaucoma even with normal eye pressure. Several risk factors can raise your chances of developing glaucoma:

  • Age over 40
  • Family history of glaucoma
  • High eye pressure
  • Diabetes
  • High blood pressure
  • Thin corneas
  • Previous eye injury
  • Being of African, Asian, or Hispanic descent
  • Because these risks add up, regular eye exams are important. Early checks can catch glaucoma before it harms your vision.

    How Glaucoma is Diagnosed

    Eye doctors use several tests to diagnose glaucoma. First, they measure your eye pressure. This test is called tonometry. Next, they check your optic nerve for damage. They may also test your side vision. Sometimes, doctors use special images to look at your eye’s structure. These steps help find glaucoma early. Early diagnosis means better treatment and less risk of vision loss.

    Treatment Options for Glaucoma

    Glaucoma treatment aims to lower eye pressure. This helps prevent further damage to the optic nerve. Treatment options for glaucoma include:

  • Prescription eye drops to reduce eye pressure
  • Oral medications if drops are not enough
  • Laser therapy to improve fluid drainage
  • Surgery for severe cases or when other treatments do not work
  • Your doctor will choose the best treatment based on your needs. With regular care, many people manage glaucoma and keep their vision.

    Lifestyle Tips and Prevention

    Although you cannot always prevent glaucoma, healthy habits can help. Here are some tips to lower your risk:

  • Get regular eye exams, especially if you have risk factors
  • Maintain a healthy weight
  • Exercise regularly, but avoid activities that raise eye pressure
  • Control blood pressure and diabetes
  • Wear eye protection during sports or risky activities
  • Take prescribed eye drops as directed
  • By following these steps, you can help protect your eyes. Early action makes a big difference in preventing glaucoma-related vision loss.

    When to See an Eye Specialist

    If you notice any changes in your vision, do not wait. See an eye specialist as soon as possible. Even if you have no symptoms, regular eye exams are important. Early detection of glaucoma can save your sight. Remember, many people do not notice symptoms until the disease is advanced. Therefore, routine checks are the best way to catch glaucoma early.
