Glaucoma is one of those eye conditions that can sneak up on you. Often called the “silent thief of sight,” it can progress quietly until noticeable vision loss occurs.
But it doesn’t have to be that way. Open angle is asymptomatic. Here are 5 signs that might indicate angle closure glaucoma:
- Blurred vision
- Seeing halos around lights
- Experiencing eye pain or pressure
- Eye redness
- Gradual loss of peripheral vision
If any of these sound familiar, it’s time to schedule an eye exam and protect your sight.
What Is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, which is crucial for good vision. Damage is often accompanied by abnormally high pressure in your eye, but may still occur with normal eye pressures. Over time, glaucoma can lead to permanent vision loss or even blindness if not treated.
Types of Glaucoma
There are 2 main types of glaucoma:
- Open-Angle Glaucoma: The most common form, where the drainage angle formed by the cornea and iris remains open, but there is still damage to the optic nerve.
- Angle-Closure Glaucoma: Less common but more urgent, involving a rapid increase in eye pressure due to a blockage in drainage of the fluid in the eye.
Why It’s Called the “Silent Thief”
Glaucoma earned this nickname because it often has no symptoms in its early stages. The vision loss usually starts with a peripheral or side vision, making it easy to go unnoticed until significant damage has occurred.
What Causes Glaucoma?
Intraocular Pressure
Elevated intraocular pressure (IOP) is the most significant risk factor for glaucoma, which can damage the optic nerve. When pressure builds up, the eye’s fluid (aqueous humour) doesn’t drain properly.
Genetic Factors
Genetics can also play a big role. If you have a family history of glaucoma, your risk can increase significantly. Regular eye exams are essential for early detection if glaucoma runs in your family.
Early Signs of Glaucoma
Blurred Vision
One of the signs of angle-closure glaucoma is blurred vision. Blurred vision may occur because increased eye pressure affects the optic nerve or due to fluid buildup that disrupts the normal function of the eye.
Blurred vision might be temporary at first, making it easy to dismiss. However, if you experience it frequently, it’s time to visit an optometrist for a thorough check-up.
Keep a diary of your symptoms. Note the time of day and activities associated with episodes of blurred vision. This information can be valuable for your healthcare provider.
Halos Around Lights
Seeing halos around lights is another warning sign of angle closure glaucoma. Halos are bright circles surrounding a light source, often displaying various colours.
Halos can occur due to corneal edema, or swelling of the cornea, caused by increased eye pressure. This affects the way light enters the eye, creating the halo effect.
If you notice halos around lights, especially when combined with other symptoms like blurred vision or eye pain, consult an optometrist immediately.
Eye Pain or Pressure
Eye pain or pressure is a more alarming symptom that should never be ignored. You may feel a dull ache or a sharp, stabbing pain. Some people describe it as a feeling of heaviness or fullness in the eye.
Discomfort or pain can result from elevated intraocular pressure affecting the optic nerve and other eye structures. In severe cases, it can indicate angle-closure glaucoma, which requires immediate medical attention.
Eye pain coupled with blurred vision or halo symptoms is a red flag. Seek medical advice as soon as possible to prevent further damage.
Redness in the Eyes
Red eyes occur when the blood vessels on the eye’s surface become swollen or irritated. Irritation can happen due to increased eye pressure or inflammation.
Occasional redness might not be a cause for alarm. However, chronic redness, particularly if accompanied by other symptoms, should be evaluated by an optometrist.
While waiting for your appointment, avoid rubbing your eyes and try using over-the-counter artificial tears to relieve discomfort. But remember, these are temporary measures and not a replacement for professional medical advice.
Gradual Loss of Peripheral Vision
One of the most telling signs of glaucoma is the gradual loss of peripheral vision. You might find that you’re bumping into objects more often or that your side vision seems to be narrowing.
You can do a simple self-test by covering one eye and focusing straight ahead. Note how much you can see out of the corners of your eyes. Repeat with the other eye. If you notice a significant difference, seeing an optometrist is time.
Early detection is crucial because vision cannot be restored once it is lost. Regular eye exams can catch these subtle changes before they become severe.
How to Treat Glaucoma
While glaucoma can’t be cured, it can be managed effectively with the proper treatment.
Medications
The most common treatment is prescription eye drops designed to reduce eye pressure. These drops can either decrease the fluid the eye produces or improve drainage.
Surgical Options
If medications aren’t enough, surgical options are available. Procedures like trabeculectomy or laser therapy can help improve fluid drainage and reduce eye pressure.
