January is Glaucoma Awareness Month, making it the perfect time to focus on this sight-threatening condition that affects millions of Americans. Did you know that in 2022, an estimated 4.22 million people in the U.S. had glaucoma? Of those, 1.49 million people had vision-affecting glaucoma, meaning their quality of life was significantly impacted.
Glaucoma is often called the “sneak thief of sight” because it develops slowly and without symptoms in its early stages. By the time you notice changes in your vision, irreversible damage may already be done. Regular eye exams and understanding the risks are your best defenses against this silent vision thief.
Read on to know what glaucoma is, its symptoms, underlying causes, and how treatments like glaucoma laser surgery and LASIK eye surgery can help manage this condition.
What Is Glaucoma?
Glaucoma is an eye condition that damages the optic nerve, often due to increased pressure inside the eye (intraocular pressure). This damage disrupts the transmission of visual information to the brain, leading to vision loss and, in severe cases, blindness.
- How It Progresses: Glaucoma usually begins without symptoms. Most people don’t realize they have it until peripheral (side) vision is affected.
- Who’s at Risk: While glaucoma primarily affects adults over 40, it can also occur in younger adults, children, and infants.
Glaucoma is often confused with other common eye conditions like cataracts. While both can impact your vision, they are fundamentally different. Read our blog to learn more about the differences between cataracts and glaucoma.
Key Symptoms of Glaucoma
1. Open-Angle Glaucoma Symptoms
This is the most common type of glaucoma. Symptoms are usually late to appear, which is why regular eye exams are critical.
- Gradual loss of peripheral vision.
- Tunnel vision in advanced stages.
2. Angle-Closure Glaucoma Symptoms
This less common form can come on suddenly and requires immediate medical attention. Symptoms include:
- Severe eye pain and headache.
- Blurred vision and halos around lights.
- Nausea and vomiting.
3. Normal-Tension Glaucoma Symptoms
Even with normal eye pressure, damage to the optic nerve can occur, leading to:
- Blurred vision.
- Blind spots in your field of vision.
4. Congenital Glaucoma Symptoms
Seen in infants, this type includes:
- Cloudy corneas.
- Excessive tearing.
- Sensitivity to light.
What Causes Glaucoma?
The exact cause of glaucoma isn’t always clear, but most cases result from fluid buildup in the eye due to blockages or overproduction. This increases pressure, damaging the optic nerve.
Common Causes Include:
- Blocked Drainage Channels: Prevent fluid from leaving the eye.
- Injury or Inflammation: Trauma or infection can lead to secondary glaucoma.
- Genetics: A family history increases your risk significantly.
- Underlying Conditions: Diseases like diabetes or high blood pressure can contribute to glaucoma.
Types of Glaucoma
Understanding the type of glaucoma you have is crucial for determining the best treatment:
- Open-Angle Glaucoma: The most common type where drainage channels become less effective over time.
- Angle-Closure Glaucoma: A sudden blockage that raises eye pressure quickly—a medical emergency.
- Normal-Tension Glaucoma: Optic nerve damage occurs despite normal intraocular pressure.
- Secondary Glaucoma: Caused by another condition, such as cataracts or diabetes.
- Congenital Glaucoma: A rare condition in infants due to abnormal development.
Glaucoma Risk Factors
Are you at risk? Certain factors increase your likelihood of developing glaucoma:
- Age: Over 40, especially if over 60.
- Ethnicity: African Americans, Hispanics, and Asians are at higher risk.
- Family History: A strong genetic link.
- Other Conditions: Diabetes, high blood pressure, and certain eye conditions.
If you’re in any of these groups, it’s essential to schedule regular comprehensive eye exams.
Treatment Options for Glaucoma
Glaucoma can’t be cured, but treatments can manage it and preserve your vision. Options include:
1. Medications
Eye drops and oral medications help lower intraocular pressure by either reducing fluid production or improving drainage.
2. Glaucoma Laser Surgery
This minimally invasive procedure helps reduce eye pressure by increasing fluid drainage or creating a new drainage pathway.
- Types of Laser Surgery: Trabeculoplasty, Iridotomy, and Cyclophotocoagulation.
- Benefits: Quick recovery time and minimal discomfort.
3. Microsurgery
In advanced cases, procedures like trabeculectomy create new channels for fluid drainage.
4. Minimally Invasive Glaucoma Surgeries (MIGS)
These newer techniques are less invasive, often combined with LASIK eye surgery for patients with multiple conditions.
How to Prevent Glaucoma Progression
Early detection is your best defense against vision loss. Here’s what you can do:
- Get Regular Eye Exams: Especially if you’re over 40 or in a high-risk group.
- Follow Your Treatment Plan: Whether it’s eye drops or glaucoma laser surgery, consistency is key.
- Adopt a Healthy Lifestyle: Eat a nutrient-rich diet, stay active, and avoid smoking.
Protect Your Vision Before It’s Too Late
Glaucoma is a leading cause of blindness, but it doesn’t have to be. With early detection, regular check-ups, and treatments like glaucoma laser surgery or LASIK eye surgery, you can preserve your sight and maintain your quality of life.
Don’t wait for symptoms to show up—by then, it might be too late. January is Glaucoma Awareness Month, so take the first step today. Schedule your eye exam and ensure your eyes are healthy for years to come.
Your vision matters. Take action now!
