What to Look Out For: Recognizing the Symptoms of Glaucoma


Glaucoma is a group of related eye disorders that can slowly or suddenly cause damage to the optic nerve, which can eventually lead to vision loss or even total blindness. Early detection and treatment can prevent or slow down the vision loss caused by glaucoma. Understanding the symptoms of glaucoma can help you recognize the disease and seek medical intervention when needed.

Common Symptoms of Glaucoma

The symptoms of glaucoma can vary depending on the type and severity of the condition. Some of the most commonly experienced symptoms include:

  • Redness of the Eye: The eye may become red or bloodshot due to increased pressure within the eye or inflammation caused by glaucoma.
  • Severe Eye Pain: Acute angle-closure glaucoma can cause intense pain in the eye due to the rapid increase in intraocular pressure.
  • Nausea and Vomiting: Rapid increases in eye pressure can also cause nausea and vomiting, often accompanied by severe eye pain.
  • Blurred or Distorted Vision: Glaucoma can cause difficulty focusing on objects, which may manifest as blurriness or distortion in the affected eye(s).
  • The Appearance of Rainbow-Colored Circles around Lights: This phenomenon, known as halos, occurs when light is refracted due to increased fluid pressure in the eye.
  • Rapid Loss of Vision: In acute angle-closure glaucoma, vision loss can occur suddenly and progress rapidly.

Differences in Symptoms Based on Types of Glaucoma

Open-Angle Glaucoma

  • Gradual peripheral vision loss, often starting in just one eye
  • Tunnel vision in advanced stages

Angle-Closure Glaucoma

  • Sudden symptoms, such as eye pain, redness, and blurred vision
  • Severe headache, not necessarily limited to the area around the affected eye
  • Rapid vision loss (this is considered a medical emergency)

Normal-Tension Glaucoma

  • No unusual eye pain or redness
  • Limited vision in the dark
  • Drastic optic nerve damage, even with normal eye pressure

Risk Factors for Glaucoma

The risk of developing glaucoma increases with factors such as age, family history of glaucoma, certain medical conditions (diabetes and hypertension), eye injuries or conditions, and ethnic background. If you fall into a high-risk group, it is crucial to attend regular eye check-ups and monitor any changes in your vision.

What Happens If You Ignore These Symptoms?

Early detection is vital in treating glaucoma and preserving vision. Ignoring symptoms, delaying medical intervention, or skipping regular eye examinations can lead to irreversible vision loss or even total blindness. Timely treatment can significantly slow down or halt the progression of the disease, allowing you to maintain your vision and lifestyle.

When to Seek Medical Help

Acute angle-closure glaucoma requires immediate medical attention as it can lead to permanent vision damage in just a few hours. If you experience severe eye pain, redness, sudden vision changes, or any combination of these symptoms, seek emergency care.

For those at high risk or displaying signs of other types of glaucoma, scheduling regular eye check-ups is crucial. Consult with your optometrist, ophthalmologist, or primary care physician if your symptoms persist or worsen.

Understanding and recognizing the symptoms of glaucoma is essential for early detection and effective treatment. Do not ignore any changes in your vision or eye health, and take the necessary precautions to protect your eyesight before irreversible damage occurs.

If you suspect that you or someone you know may have symptoms of glaucoma, do not hesitate to reach out to your optometrist or healthcare provider. Early intervention and proper care can make a notable difference in protecting your vision. Remember, your eye health should never be taken for granted!
