What Is Glaucoma and Why Is Treatment Important?

Glaucoma is a group of eye conditions that can lead to optic nerve damage, often caused by increased intraocular pressure (IOP). Without early diagnosis and proper treatment, glaucoma can result in permanent vision loss and is one of the leading causes of blindness worldwide. However, timely glaucoma treatment can help preserve your sight.

At Mudgil Eye Associates, we specialize in the early detection and management of glaucoma to safeguard your vision and maintain your quality of life.

Types of Glaucoma

Glaucoma can present in various forms, and each type requires a unique approach to diagnosis and treatment:

1. Open-Angle Glaucoma

The most common form, open-angle glaucoma, occurs when the eye's drainage system malfunctions, leading to a gradual increase in eye pressure. Since symptoms may be absent in the early stages, regular eye exams are crucial for early detection.

2. Angle-Closure Glaucoma

In this form, the drainage angle closes, preventing fluid from draining and causing a sudden increase in pressure. Symptoms include severe eye pain, blurred vision, headaches, and nausea. Angle-closure glaucoma is a medical emergency that requires immediate treatment.

3. Normal-Tension Glaucoma

Even with normal eye pressure, normal-tension glaucoma can cause damage to the optic nerve. While less common, this type can still result in significant vision loss if untreated.

4. Congenital Glaucoma

This rare type affects infants and young children due to abnormal eye development. Early intervention is crucial to prevent permanent vision impairment.

Symptoms of Glaucoma

Often called the "silent thief of sight," glaucoma progresses slowly, and symptoms may not appear until significant vision loss occurs. Be on the lookout for these signs:

Peripheral vision loss: One of the earliest symptoms.
Blurred vision or tunnel vision: Common in advanced stages.
Eye pain: Particularly in angle-closure glaucoma.
Halos around lights: Rainbow-colored halos around lights can signal increased eye pressure.

Since symptoms often develop late, regular eye exams are critical—especially for individuals over 60 or those with risk factors such as a family history of glaucoma, diabetes, or high blood pressure.

Glaucoma Risk Factors

Several factors increase the likelihood of developing glaucoma, including:

Age: People over 60, particularly African Americans, are at higher risk.
Family History: Glaucoma can run in families.
High Eye Pressure (IOP): Elevated intraocular pressure is a major risk factor.
Ethnicity: African Americans, Hispanics, and Asians are at increased risk for certain types of glaucoma.
Medical Conditions: Conditions like diabetes, hypertension, and heart disease can increase the risk of glaucoma.

How Is Glaucoma Diagnosed?

At Mudgil Eye Associates, we employ state-of-the-art diagnostic tools to detect and manage glaucoma early, including:

Tonometry: Measures intraocular pressure.
Optic Nerve Imaging: Detects damage to the optic nerve.
Visual Field Testing: Assesses peripheral vision loss.
Gonioscopy: Examines the eye’s drainage angle for blockages.

Glaucoma Treatment Options

Though glaucoma cannot be cured, early intervention can slow its progression and protect your vision. The goal of glaucoma treatment is to lower eye pressure and prevent further damage to the optic nerve.

Glaucoma Eye Drops: The First Line of Defense

Eye drops are commonly prescribed to reduce intraocular pressure by improving fluid drainage or reducing fluid production. Types include:

Prostaglandin Analogs: Increase fluid outflow (e.g., Xalatan, Travatan Z).
Beta-Blockers: Reduce fluid production (e.g., Timoptic).
Alpha Agonists: Decrease fluid production and improve drainage (e.g., Alphagan).
Carbonic Anhydrase Inhibitors: Lower fluid production (e.g., Trusopt).‍‍
Rho Kinase Inhibitors: Enhance drainage (e.g., Rhopressa).

Using eye drops consistently as prescribed is crucial for controlling eye pressure and preventing further damage.

Selective Laser Trabeculoplasty (SLT): Non-Invasive Laser Treatment

Selective Laser Trabeculoplasty (SLT) is a laser treatment used to lower intraocular pressure in patients with open-angle glaucoma. SLT stimulates the eye’s drainage system, improving fluid outflow.

It’s a quick, outpatient procedure with minimal recovery time.Advantages of SLT include:

Non-invasive: No incisions or cuts.
Fewer side effects: Minimal damage to surrounding tissue.
Repeatable: SLT can be repeated if necessary.

Minimally Invasive Glaucoma Surgery (MIGS): A Modern Approach

Minimally Invasive Glaucoma Surgery (MIGS) is a cutting-edge treatment designed for patients with mild to moderate glaucoma. MIGS procedures create new drainage pathways to lower eye pressure with minimal trauma. The advantages of MIGS include quicker recovery, fewer risks, and less discomfort than traditional surgery.

Common MIGS procedures include:

iStent®: A small device inserted to improve fluid outflow.
Hydrus® Microstent: Widens the drainage canal.
Xen® Gel Stent: Creates a new drainage channel for fluid.
Trabectome®: Removes a small piece of tissue to enhance fluid drainage.

Surgical Options for Advanced Glaucoma

In cases where glaucoma doesn't respond to eye drops, laser treatments, or MIGS, traditional surgeries like trabeculectomy or glaucoma drainage implants may be required to create new pathways for fluid drainage.
