Glaucoma

This is the most common type of glaucoma, affecting about 90% of people with the disease. In open-angle glaucoma, the drainage angle where fluid exits the eye remains open, but the drainage system becomes less efficient over time. This type usually develops slowly without symptoms and is often discovered during routine eye exams.

In angle-closure glaucoma, the iris blocks the drainage angle, preventing fluid from leaving the eye. This can happen suddenly, causing severe eye pain, headaches, nausea, blurred vision, and seeing halos around lights. Acute angle-closure glaucoma is a medical emergency that requires immediate treatment to prevent permanent vision loss.

Some people develop optic nerve damage even when their eye pressure is in the normal range. This type is often detected by finding characteristic optic nerve changes and visual field loss despite normal eye pressure. This type of glaucoma may be related to poor blood flow to the optic nerve or increased sensitivity to pressure.

This type develops as a result of another eye condition or medical treatment and refers to any glaucoma with an identifiable underlying cause. Causes can include eye injuries, certain medications like steroids, eye inflammation, or other eye diseases. Treatment focuses on addressing both the underlying cause and managing the glaucoma.

Most people with early open-angle glaucoma notice no changes until peripheral vision becomes subtly reduced. Over time, untreated damage can constrict the visual field and eventually affect central vision. Any sudden onset of severe eye pain, headache, halos, or vision loss should be treated as an emergency.

Most glaucoma treatment starts with prescription eye drops that either reduce fluid production in the eye or improve drainage. Prostaglandin analogs are typically preferred as first-line treatment due to their effectiveness, once-daily dosing, and generally good tolerability. Different types of drops work in various ways, and many people need more than one medication for effective pressure control.

• Prostaglandin analogs improve uveoscleral outflow and are often used once nightly
• Beta-blockers reduce aqueous production and are commonly dosed once or twice daily
• Carbonic anhydrase inhibitors and alpha agonists lower pressure via complementary mechanisms
• Rho kinase inhibitors enhance outflow through the trabecular pathway and are typically used as additional therapy

Selective laser trabeculoplasty or SLT targets the trabecular meshwork to enhance fluid outflow and lower pressure without making an incision. It can be used as initial or additional therapy in appropriate cases. It is performed in our office, has a favorable safety profile, and may be repeated if the effect wanes over time.

iDose TR is an FDA-approved intracameral travoprost implant indicated to reduce intraocular pressure in patients with open-angle glaucoma or ocular hypertension. As a long-duration implant placed inside the eye, it provides continuous prostaglandin therapy and can reduce reliance on daily drops in appropriate candidates. This is a relatively new treatment option, and long-term data on its use are still emerging.

MIGS procedures use microscopic instruments and tiny devices to improve drainage with minimal tissue trauma. These procedures are generally best for patients with mild to moderate glaucoma. They are often performed at the same time as cataract surgery and typically involve faster recovery than conventional glaucoma surgeries. Options include microscopic stents that create new drainage pathways and devices that enhance the eye's natural drainage system.

When other treatments are not sufficient, traditional surgery creates a new drainage channel for fluid to leave the eye. Procedures like trabeculectomy and glaucoma drainage implants are highly effective at lowering eye pressure but carry higher risks and longer recovery times than MIGS. They are more effective for advanced or difficult-to-control glaucoma. Our experienced eye doctors carefully evaluate each patient to determine the best surgical approach for their specific situation.

Clinicians establish an individualized target pressure that balances disease severity, risk factors, and treatment tolerance to minimize progression risk. A practical initial goal often aims for at least a 20 to 30 percent reduction from baseline, with lower targets for advanced disease or documented progression.

Most people with glaucoma who receive proper treatment maintain good vision throughout their lives. While glaucoma can cause blindness if left untreated, early detection and consistent treatment are highly effective at preventing severe vision loss. The key is following your treatment plan and keeping all scheduled appointments with our eye doctors. Remember that vision loss from glaucoma is permanent and cannot be restored, which is why prevention through treatment is so important.

Glaucoma itself cannot be fully prevented, but early detection and timely pressure-lowering treatment can greatly reduce the risk of vision loss. Regular comprehensive dilated eye exams are the most effective way to find glaucoma early and start treatment before significant damage occurs.

Not always - some people have ocular hypertension without nerve damage, while others develop glaucoma at lower pressures, so a complete exam is essential. Risk and diagnosis depend on optic nerve health, angle anatomy, corneal thickness, and visual field findings in addition to pressure measurements.

Glaucoma damage is permanent and irreversible, and treatment works to prevent further loss rather than restore lost vision. Starting therapy early and maintaining follow-up offer the best chance to preserve remaining sight for life. This is why early detection is so important.

Many people with glaucoma can be successfully managed with eye drops alone. Surgery is typically recommended when medications cannot adequately control eye pressure, when side effects from drops are problematic, or when the disease continues to progress despite treatment. Our eye doctors will discuss all options and recommend the approach most likely to preserve your vision.

SLT and many glaucoma procedures are performed with numbing medicine and are usually well tolerated with only mild, temporary discomfort. The care team reviews risks, recovery, and drop schedules so healing and pressure control stay on track.

Having a parent with glaucoma does increase a child's risk, but it does not guarantee they will develop the disease. Children of people with glaucoma should have comprehensive eye exams starting in their teens or early adulthood. Early detection through regular screening is the best protection against vision loss from inherited glaucoma.

Like all medications, glaucoma eye drops can cause side effects, though most people tolerate them well. Common effects include eye irritation, redness, and changes in eye color or eyelash growth. Some drops can affect heart rate or breathing in sensitive individuals. Our eye doctors monitor for side effects and can often switch medications if problems occur.

Frequency depends on risk and findings, with many higher-risk adults advised to have exams every 1 to 2 years or as directed by their eye doctor. Those with glaucoma need individualized follow-up intervals to confirm stability or adjust treatment early. People at higher risk should prioritize routine comprehensive eye exams.

iDose TR is indicated to reduce intraocular pressure in open-angle glaucoma or ocular hypertension, but candidacy depends on anatomy, disease stage, and overall plan. Not all practices offer this relatively new implant. A comprehensive exam can determine whether a sustained-release implant, drops, laser, or surgery best matches treatment goals.

Regular exercise may help lower eye pressure and is generally beneficial for people with glaucoma. However, avoid activities that involve hanging upside down, holding your breath, or sudden jarring movements. Always discuss your exercise plans with our eye doctors to ensure they are appropriate for your specific condition.

If you miss a dose of your glaucoma medication, take it as soon as you remember unless it is almost time for your next dose. Do not double up on doses. Consistency is important for effective pressure control, so setting up reminders can help you maintain your medication schedule.

While rare, glaucoma can affect infants and children. Congenital glaucoma is present at birth, while juvenile glaucoma develops in childhood or adolescence. Signs in babies include enlarged eyes, cloudiness of the cornea, and excessive tearing. Early diagnosis and treatment are crucial for preserving vision in pediatric glaucoma cases.

These are forms of secondary open-angle glaucoma. Pigmentary glaucoma occurs when pigment from the iris clogs the drainage system, often seen in nearsighted young adults. Pseudoexfoliative glaucoma involves a flaky material that deposits throughout the eye and blocks drainage. Both types can be more aggressive than primary open-angle glaucoma and may require closer monitoring.

Follow-up frequency varies based on your specific situation. Newly diagnosed patients, those with changing treatment, or advanced disease may need visits every few weeks to months. Stable patients with well-controlled glaucoma might be seen every 3 to 6 months. Your eye doctor will determine the right schedule based on your individual needs and risk factors.
