What Are the Signs and Symptoms of Glaucoma, and When Is Surgery Recommended?

Glaucoma is a group of eye diseases that can damage the optic nerve, most often because of elevated intraocular pressure (eye pressure). Left untreated, glaucoma can gradually lead to permanent vision loss, making it one of the leading causes of blindness worldwide. Fortunately, a variety of glaucoma treatment options are available. While many patients successfully manage glaucoma without surgery, it may be recommended when eye pressure remains elevated or optic nerve damage continues to progress. At North Carolina Specialty Hospital, our experienced ophthalmologists provide surgery for glaucoma and other advanced treatment options designed to lower eye pressure, help preserve remaining vision, and support your long-term eye health.

What Are the Signs and Symptoms of Glaucoma, and When Is Surgery Recommended?

In its early stages, glaucoma often develops without noticeable signs and symptoms, which is why it’s sometimes called the “silent thief of sight.” Depending on the type of glaucoma, as the disease progresses, some people may experience:

• Gradual loss of peripheral (side) vision
• Blurred vision
• Halos around lights
• Eye pain

Because these symptoms may not appear until permanent damage has occurred, routine eye exams are essential for early detection.

One common question patients ask is, what are signs of optic nerve damage? Unfortunately, optic nerve damage usually cannot be seen or felt without a comprehensive eye examination. Your ophthalmologist looks for changes in the optic nerve and measures intraocular pressure to detect glaucoma before significant vision loss occurs. Early diagnosis and treatment remain the best way to help prevent vision loss from glaucoma.

Surgery is typically recommended when other glaucoma treatment options are no longer enough to control the disease.

Who Benefits From Glaucoma Surgery?

You may benefit from glaucoma surgery if you:

• Have uncontrolled intraocular pressure despite medications or other treatments.
• Cannot tolerate glaucoma medications because of side effects or difficulty using them consistently.
• Continue to show signs of optic nerve damage or vision loss despite treatment.
• Have moderate to advanced glaucoma that requires more aggressive pressure reduction.
• Are undergoing cataract surgery and may benefit from minimally invasive glaucoma surgery (MIGS) at the same time.
• Want to help preserve your remaining vision and slow the progression of glaucoma.

Types of Glaucoma Surgery

Several types of glaucoma procedures are available at NC Specialty Hospital. The right treatment depends on the type and severity of your glaucoma, your overall eye health, and how well previous treatments have controlled your eye pressure. Your ophthalmologist will recommend the option that offers the best opportunity to preserve your remaining vision.

Minimally Invasive Glaucoma Surgery (MIGS): This surgery is often recommended for patients with mild to moderate glaucoma, particularly those who are also having cataract surgery. These procedures use tiny incisions and specialized devices to improve the eye’s natural drainage system and lower intraocular pressure.

Glaucoma Laser Surgery: This surgery may be recommended early in treatment or when eye drops alone are not providing adequate control of intraocular pressure. One common procedure, Selective Laser Trabeculoplasty (SLT), uses laser energy to improve fluid drainage from the eye, helping to lower eye pressure. For some patients, glaucoma laser surgery can reduce the need for daily medications or delay the need for more invasive surgical procedures.

Traditional Glaucoma Surgery: For patients with moderate to advanced glaucoma or glaucoma that continues to progress despite other treatments, procedures such as trabeculectomy or tube shunt surgery may be recommended. These procedures create a new pathway for fluid to drain from the eye, providing a greater reduction in intraocular pressure than less invasive treatments.

What To Expect After Glaucoma Surgery

Recovery afterward varies depending on the procedure performed. MIGS and glaucoma laser surgery often have shorter recovery times than traditional glaucoma surgery. Your ophthalmologist will provide detailed recovery instructions based on your individual treatment plan.

Following your procedure, you can expect:

• Follow-up appointments to monitor healing, measure intraocular pressure, and ensure your eye is responding well to treatment.
• Prescription eye drops to help reduce inflammation, prevent infection, and support healing.
• Temporary activity restrictions, such as avoiding heavy lifting, strenuous exercise, rubbing your eyes, or swimming until your surgeon says it is safe.
• Gradual recovery, with many patients resuming normal daily activities within a few days to a few weeks, depending on the procedure.

Even after successful surgery, ongoing glaucoma care remains essential. Regular eye exams allow your ophthalmologist to monitor your intraocular pressure, evaluate your optic nerve, and determine whether additional treatment or medication is needed to help protect your vision over time.

Frequently Asked Questions About Glaucoma Surgery

Is Glaucoma Surgery Permanent?

Glaucoma surgery is designed to lower intraocular pressure and help slow or prevent further damage to the optic nerve, but it is not a cure for glaucoma. In some cases, the effects of surgery may lessen over time, and additional treatment or medication may be needed to continue managing the disease.

How Successful Is Glaucoma Surgery?

Success depends on several factors, including the type and severity of glaucoma, the procedure performed, and how your eye heals. Many patients experience a significant reduction in intraocular pressure, helping preserve their remaining vision and reduce the risk of further optic nerve damage. Your ophthalmologist can discuss the expected outcomes for your specific condition.

How Long Does Glaucoma Surgery Take?

Most procedures take between 30 and 90 minutes, depending on the type of surgery being performed. Many patients return home the same day, although your recovery time will vary based on the procedure and your individual healing process.

Can Glaucoma Come Back After Surgery?

Glaucoma itself does not go away after surgery, so ongoing monitoring is essential. Some patients may eventually require additional medications, laser treatment, or another procedure to keep glaucoma under control. Regular follow-up appointments help your ophthalmologist monitor your eye health and recommend treatment if needed.

Is Glaucoma Surgery Painful?

Most patients experience little or no pain during surgery because the eye is numbed with local anesthesia, often with medication to help you relax. After surgery, it is common to have mild discomfort, irritation, or blurred vision for a short time, but these symptoms typically improve as your eye heals. Your surgeon will provide instructions and medications to help keep you comfortable during recovery.
