Understanding Glaucoma
Glaucoma is often called the “sneak thief of sight” because it typically develops without noticeable symptoms until significant vision loss has occurred. This group of eye diseases damages the optic nerve—the vital connection between your eye and brain—most commonly due to elevated pressure within the eye (intraocular pressure or IOP).
Types of Glaucoma
Several types of glaucoma exist today, presenting a risk of vision loss. Of the many types of glaucoma, angle-closure, normal-tension, and open-angle glaucoma are among the most common forms.
Open-Angle Glaucoma
The most common form of glaucoma occurs when fluid drainage from your eye becomes gradually inefficient over time. This slow-developing condition causes pressure to build up inside your eye, eventually damaging the optic nerve. Most patients experience no symptoms until peripheral vision begins to deteriorate.
Angle-Closure Glaucoma
This less common but more urgent form develops when your eye’s drainage canals become suddenly blocked. The rapid pressure increase can cause severe eye pain, headaches, blurry vision, and nausea. Angle-closure glaucoma is considered a medical emergency requiring immediate treatment to prevent permanent vision loss.
Normal-Tension Glaucoma
In this unique form, optic nerve damage occurs despite normal eye pressure levels. The exact cause remains unclear but may involve poor blood flow to the optic nerve or structural weaknesses. People with cardiovascular conditions face a higher risk for this type, which progresses without obvious symptoms.
Benefits of Glaucoma Treatment
Preserved Peripheral Vision
Early glaucoma treatment helps maintain your peripheral vision, which is typically the first affected by optic nerve damage. At Clear Lake Eye Center, our comprehensive glaucoma screening catches these changes before you notice them. Preserving peripheral vision allows you to continue driving safely, navigate confidently in crowded spaces, and stay aware of your surroundings during daily activities.
Reduced Risk of Emergency Situations
Proper glaucoma management significantly reduces your risk of experiencing acute pressure spikes that can cause severe pain and rapid vision deterioration. Regular monitoring of your intraocular pressure identifies concerning patterns before they develop into emergencies. Preventative glaucoma care provides peace of mind knowing you’re protected from sudden sight-threatening complications.
Protection for Both Eyes
Glaucoma often affects both eyes, though frequently at different rates. Our specialized glaucoma testing evaluates each eye individually, allowing for customized treatment approaches that address the specific needs of each eye. This tailored glaucoma management strategy protects your overall visual field and maintains balanced vision between both eyes.
Minimized Treatment Side Effects
Modern glaucoma therapy offers increasingly targeted approaches with fewer side effects than treatments of the past. Our optometrists carefully select glaucoma medications and procedures that effectively control your eye pressure while minimizing discomfort or inconvenience. Your glaucoma treatment plan considers your lifestyle, existing medications, and personal preferences.
Enhanced Night Vision Maintenance
Glaucoma can significantly impact your ability to see in low-light conditions, making nighttime activities challenging. Timely glaucoma intervention helps preserve the specialized retinal cells responsible for night vision. Maintaining this visual function through consistent glaucoma care allows you to continue evening driving, navigate your home safely at night, and enjoy nighttime social activities.
Our Glaucoma Treatment Process
- Pressure Testing
- Optic Nerve Examination
- Visual Field Assessment
- Pressure Management
- Scheduled Monitoring
Comprehensive Pressure Testing
Your glaucoma evaluation begins with precise intraocular pressure measurement to detect elevated levels that could damage your optic nerve. Our optometrists use advanced tonometry techniques to accurately assess your eye pressure during each visit. This crucial baseline measurement helps us determine your risk level and guides our treatment recommendations for protecting your vision.
Detailed Optic Nerve Examination
We thoroughly examine your optic nerve using ophthalmoscopy and Optical Coherence Tomography (OCT) to identify any existing damage or warning signs. These specialized glaucoma tests provide high-resolution images of your nerve fiber layer thickness and structural integrity. Early detection of optic nerve changes allows us to intervene before you experience noticeable vision loss.
Visual Field Assessment
Your peripheral vision is carefully mapped using computerized visual field testing to identify any blind spots or vision deficits. This painless glaucoma screening reveals patterns of vision loss that may not be apparent to you during daily activities. Regular visual field testing helps us track your condition over time and measure the effectiveness of your treatment plan.
Personalized Pressure Management
Based on your specific type of glaucoma and test results, we create a targeted treatment approach to lower your intraocular pressure to a safe level. Your plan may include prescription eye drops, oral medications, laser therapy options, or surgical interventions if necessary. We carefully explain each recommendation and help you understand how it works to protect your vision.
Scheduled Monitoring Visits
Regular follow-up appointments are essential for successful long-term glaucoma control. We establish a personalized monitoring schedule based on your condition’s severity and response to treatment. These important check-ups include pressure measurements, visual field testing, and optic nerve imaging to detect any changes requiring prompt attention or treatment adjustments.
How We Test for Glaucoma
While glaucoma can develop symptom-free, many forms of this disease raise your internal eye pressure. Your intraocular pressure (IOP) is the fluid pressure inside your eye, and high IOP increases your risk of glaucoma. We have several ways to measure your IOP. Measuring your IOP is a standard part of every comprehensive eye exam we perform.
We will also complete several additional tests for an accurate diagnosis including Ophthalmoscopy, pachymetry, gonioscopy, visual fields test, and O.C.T.

FAQs
What is glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, typically due to elevated pressure within the eye. This damage leads to progressive, irreversible vision loss that often begins with peripheral vision and can advance to complete blindness if left untreated. The condition usually develops slowly and painlessly, which is why it’s commonly known as the “silent thief of sight.”
What causes glaucoma?
The primary cause of glaucoma is increased intraocular pressure resulting from improper fluid drainage in the eye. In a healthy eye, fluid flows freely through a mesh-like channel, but when this channel becomes blocked or isn’t functioning properly, fluid builds up and creates pressure that damages the optic nerve. Other factors that may contribute to glaucoma include poor blood flow to the optic nerve, genetic predisposition, and certain medical conditions like diabetes and hypertension.
Is glaucoma hereditary?
Yes, glaucoma has a strong genetic component, with family history being a significant risk factor for developing the condition. If you have a parent or sibling with glaucoma, your risk of developing it increases by four to nine times compared to someone without a family history. However, genetics is just one factor among many that determine glaucoma risk, including age, ethnicity, eye anatomy, and certain medical conditions.
Can glaucoma be cured?
Currently, there is no complete cure for glaucoma, as vision loss from optic nerve damage cannot be reversed. However, with early detection and appropriate treatment, further vision loss can be slowed or prevented in most cases. Treatment options focus on lowering intraocular pressure through medications, laser procedures, or surgery, depending on the type and severity of your glaucoma.
How to prevent glaucoma?
While glaucoma cannot be completely prevented, you can significantly reduce your risk by scheduling regular comprehensive eye exams for early detection, especially if you have risk factors like family history or are over 40. Maintaining a healthy lifestyle that includes regular exercise, a balanced diet rich in antioxidants, and avoiding smoking can support overall eye health. Managing other health conditions like diabetes and high blood pressure is also crucial, as these can contribute to glaucoma development and progression.
