Understanding Glaucoma
Glaucoma is one of the leading causes of vision loss worldwide, and it often progresses without apparent symptoms. At Treasure Coast Eye Specialists, we’re committed to empowering you to protect your vision with early detection and advanced treatment options tailored to your unique needs. By being proactive and getting regular eye exams, you can take control of your eye health and potentially prevent vision loss.
Glaucoma refers to a group of eye conditions that damage the optic nerve, typically due to elevated intraocular pressure. Left untreated, this pressure can lead to partial or total vision loss. While glaucoma is more common in people over 60, it can affect adults of all ages—and even infants in rare cases.
What Causes Glaucoma?
The root cause of glaucoma is often increased intraocular pressure. Your eye naturally produces a fluid called aqueous humor, which should flow out of the eye through a drainage system near the cornea and iris. If this drainage system becomes blocked or functions poorly, fluid builds up, raising the pressure inside the eye and placing stress on the optic nerve.
Although the exact cause isn’t always known, several factors may raise your risk:
- Age (especially 60+)
- Family history of glaucoma
- High or low blood pressure
- Diabetes or heart disease
- Eye injuries or past eye surgeries
- Long-term corticosteroid use
- Thin corneas
- Extreme nearsightedness or farsightedness
- Ethnicity (increased risk for Black, Asian, and Hispanic populations)
Types of Glaucoma
Several forms of glaucoma exist, each requiring a different approach to treatment:
- Open-Angle Glaucoma: The most common type in the U.S., characterized by slow, symptomless progression.
- Normal-Tension Glaucoma: Damage occurs even with normal eye pressure levels—possibly linked to low blood pressure.
- Angle-Closure Glaucoma: A medical emergency. Symptoms include severe eye pain, redness, nausea, and blurred vision. Seek immediate care.
- Congenital Glaucoma: Present at birth due to abnormal eye development.
- Secondary Glaucoma: Develops as a result of another condition, like diabetes or uveitis.
- Pigmentary and Exfoliation Glaucoma: Caused by pigment or debris blocking fluid drainage.
Early Signs of Glaucoma
Glaucoma often develops quietly. Many patients don’t realize they have it until vision loss begins. The earliest sign is usually a gradual loss of peripheral (side) vision.
Watch for these symptoms:
- Blurred vision
- Halos around lights
- Headaches
- Eye pain or redness
- Nausea or vomiting
- Dilated pupils
How Is Glaucoma Treated?
There’s no one-size-fits-all approach to treating glaucoma. The goal is to lower intraocular pressure and preserve your vision. Depending on your diagnosis, treatment may include:
Prescription Eye Drops
- Improve fluid drainage or reduce fluid production
- Medications include prostaglandins, beta blockers, alpha-adrenergic agonists, and more.
Oral Medications
- Used when eye drops alone aren’t effective
- Can enhance drainage or reduce pressure
Laser Procedures
- Non-invasive, in-office treatments to improve fluid outflow
- Often used for open-angle or angle-closure glaucoma.
Surgical Options
- Trabeculectomy: Creates a new drainage path by removing part of the eye’s meshwork
- Drainage Implants: Small devices inserted to regulate eye pressure
- Often used when medication and laser therapy aren’t enough.
Can Glaucoma Be Prevented?
While glaucoma can’t always be prevented, early detection and consistent care make a huge difference in managing the condition. Regular eye exams are your best defense against vision problems. By understanding the importance of regular eye exams and making them a priority, you can stay informed and aware of the best practices for managing your eye health.
During your exam, you can expect:
- Eye pressure testing (tonometry)
- Dilation and optic nerve evaluation
- Visual field tests to assess peripheral vision
- Drainage angle assessments
- Detailed review of your personal and family medical history
Take Charge of Your Eye Health
If you’re at risk for glaucoma—or simply due for a comprehensive eye exam—don’t wait. Early detection could mean the difference between preserving your vision and losing it.
