Top 10 Modern Glaucoma Treatments

Written by Andrew Le, MD

UpdatedMay 29, 2024

Glaucoma, affecting over 3 million people in the US, is a leading cause of vision loss, often with few early symptoms. This eye condition increases pressure on the optic nerve and can lead to irreversible damage if not managed effectively.

Traditional methods for treating glaucoma typically involve lowering intraocular pressure. This is done through medication, laser therapy, or surgery. However, these methods can have potential risks and require long recovery times. This highlights the importance of modern glaucoma treatments.

These newer methods, including advanced medications and minimally invasive surgeries, offer a safer, more effective approach with quicker recovery, revolutionizing how we manage this challenging condition.

This article will explore the top 10 modern glaucoma treatments, examining their efficacy, safety, and patient-specific considerations. We will also discuss the challenges in evaluating these interventions and the importance of considering factors like patient preferences and treatment selection costs.

Understanding Glaucoma

Glaucoma causes slow loss of peripheral vision and can eventually lead to loss of central vision.

Glaucoma predominantly affects about 3% of the population over 50 years old, standing as a leading cause of irreversible visual impairment in older individuals. The disease often remains undetected in its initial stages due to its asymptomatic nature, leading to substantial vision loss before diagnosis.

Risk factors such as age, ethnicity, family history, genetic factors, and physical eye conditions cause this silent progression.

Glaucoma develops slowly, and initial symptoms are not noticeable, so a comprehensive dilated eye exam and measuring intraocular pressures are required for diagnosis.

Now that we know more about glaucoma, let’s look into its types.

Types of Glaucoma

Glaucoma is classified into open-angle and angle-closure glaucoma, each with distinct characteristics and implications for eye health.

  1. Open-angle glaucoma is the more common form that develops gradually, which impairs the eye's ability to drain fluid effectively. This leads to increased eye pressure and subsequent optic nerve damage.
  2. Angle-closure glaucoma, also known as closed-angle or narrow-angle glaucoma, develops when the iris is too close to the eye's drainage angle, potentially leading to blockage.

Both types of glaucoma highlight the need for regular eye examinations to prevent irreversible vision loss due to these often asymptomatic conditions in their early stages​​.

🩺 Health Note

Having certain medical conditions, such as diabetes, high blood pressure, migraines, and sickle cell anemia can also increase the risk of developing glaucoma.

Surgery and Laser Treatments

Other treatment options for glaucoma involve laser and surgical procedures to help lower the intraocular pressure in the eyes. Here are the options available in detail to help manage glaucoma.

SLT is designed to lower eye pressure effectively, providing an alternative to conventional glaucoma treatments. SLT reduces IOP by about 20% to 30% and is effective in about 80% of patients, with results visible within three months.

The procedure's effects can last up to five years, with the option for repeat treatments. It involves applying laser energy to the eye's drainage tissue (trabecular meshwork), which is the natural fluid drain. This process stimulates a chemical and biological change in the tissue, enhancing fluid drainage and subsequently lowering IOP.

This cold laser technique results in less scar tissue formation and minimal pain. However, the full effect of the treatment might take one to three months to manifest. The estimated cost of this procedure is around $2000.


  • Results are typically visible within three months.
  • Effects can last up to five years, with options for repeat treatments.
  • Cold laser technique results in minimal scar tissue and pain.


  • Full effect may take one to three months to manifest.
  • High cost might be a consideration for some patients.

Femto Laser-Assisted Trabeculotomy, commonly referred to as FLIGHT is a non-invasive procedure. It enhances aqueous humor outflow in glaucoma patients by creating a precise channel connecting the anterior chamber to Schlemm's canal.

This is achieved using ViaLase® Laser technology, which delivers femtosecond laser pulses through the cornea and into the iridocorneal angle.

FLIGHT has shown promising results in reducing intraocular pressure (IOP). In a study, the mean IOP was reduced by 34.6% from 22.3mm Hg to 14.5mm Hg over 24 months. Additionally, 82.3% of eyes in the study achieved a 20% or greater reduction in IOP.

The procedure's safety profile is favorable, with no serious device-related adverse events reported after two years​. Further research is necessary to fully understand its application across different patient profiles, particularly in cases of narrow-angle glaucoma.


  • Non-invasive and does not require opening the eye.
  • Showed significant reduction in intraocular pressure over 24 months.
  • High safety profile with no serious adverse events reported in studies.
  • Treats a small portion of the angle, reducing potential harm.


  • Effectiveness in narrow-angle glaucoma cases requires further research.
  • Challenges in visualizing the trabecular meshwork in certain eyes.
  • Risk of iris incarceration following channel creation in some cases.
Minimally Invasive Glaucoma Surgery (MIGS)

MIGS techniques reduce intraocular pressure (IOP) by enhancing the eye's natural aqueous outflow. The procedures include bypassing the trabecular meshwork with stents, dilating Schlemm's canal, augmenting uveoscleral outflow with microstents, or decreasing aqueous production through ciliary body ablation.

These procedures are typically performed through a small incision in the cornea. MIGS stands out due to its high safety profile, minimal disruption of normal ocular anatomy, and effectiveness in lowering IOP. These surgeries are less invasive, carry a much lower risk of serious complications, and offer rapid recovery for patients.

MIGS, while safer, may offer less IOP reduction compared to traditional surgeries. Also, the effectiveness varies based on the specific technique and the patient's condition.


  • High safety profile with lower risk of complications like hypotony or hemorrhages.
  • Minimal alteration to normal ocular anatomy.
  • Meaningful IOP reduction, potentially reducing the need for medications.
  • Quick postoperative recovery.


  • May provide less IOP reduction compared to traditional glaucoma surgeries.
  • Effectiveness varies based on technique and patient condition.

The Future of Glaucoma Treatment

Advancements in glaucoma treatment are on the horizon, offering new hope for managing this condition. Three innovative areas stand out: nanotechnology, neuroprotection and regenerative medicine, and gene therapy.

  • Nanotechnology: Nanomedicine introduces nano-delivery systems for glaucoma treatment, offering sustained medication release and improved bioavailability. This technology promises more effective drug delivery with lower dosages and the development of continuous IOP monitoring implants.
  • Neuroprotection and Regenerative Medicine: This approach uses neuroprotective agents and stem cells to slow disease progression and potentially regenerate damaged optic nerves.
  • Gene Therapy: Genetic research aims to identify glaucoma-linked genes to develop personalized therapies. Recent studies have successfully reversed glaucoma-induced vision loss in animal models by restoring youthful gene function in retina cells.
  • NCX 470 (Nicox SA): In animal studies, this nitric oxide-donating prostaglandin analog has shown superiority over bimatoprost in lowering intraocular pressure (IOP). In Phase II trials, it demonstrated significant IOP reduction compared to latanoprost, potentially offering a stronger IOP-lowering effect with once-daily dosing​​.
  • Cromakalim prodrug 1 (CKLP1): As an ATP-sensitive potassium channel opener, CKLP1 targets the reduction of episcleral venous pressure (EVP). This mechanism could allow for IOP reduction comparable to surgical interventions, potentially achieving lower IOP levels without the need for surgery. While still in the preclinical stage, it has shown promising results in animal studies​​.
  • QLS-101 (Qlaris Bio): Another ATP-sensitive potassium channel modulator, QLS-101, is intended to reduce EVP-like CKLP1. Currently, in Phase II trials, it may offer an alternative noninvasive treatment to surgery and could spare patients from side effects commonly seen with prostaglandins.

Final Thoughts

The effective management of glaucoma is crucial for preserving vision and preventing blindness. Modern glaucoma treatments like Iyuezeh's preservative-free drops, Rhopressa's drainage-enhancing mechanism, and minimally invasive surgeries through small incisions like MIGS are revolutionizing care.

While safer and personalized, ongoing assessments through eye exams and field testing are vital to monitor progression and treatment efficacy while offering improved efficacy and safety profiles, it’s vital to have ongoing assessments to monitor disease progression and treatment effectiveness through comprehensive eye examinations and visual field testing.

FAQs on Modern Glaucoma Treatments

Can you get glaucoma in both eyes?

Yes, it is possible to develop glaucoma in the other eye if only one eye is affected initially. Some with closed-angle glaucoma in one eye can have a 40% to 80% chance of getting the same glaucoma. Each eye must be monitored and treated to prevent vision loss.

Can glaucoma be treated permanently?

No, glaucoma cannot be permanently cured. It requires ongoing management as there is currently no treatment for glaucoma that helps reverse damage or permanently eliminate risks that cause elevated eye pressure.

Is glaucoma treatment lifelong?

Yes, glaucoma treatment is a lifelong commitment in most cases. Patients need regular monitoring and adjustments to therapy over time to preserve vision and prevent progression.

Does laser treatment cure glaucoma?

Laser treatment for glaucoma works very well for most people but it doesn't work for everyone. Most people will still need to keep taking glaucoma medications even after laser treatment. One will need to wait 4 to 6 weeks after laser treatment to find out if it worked.
