Signs of Glaucoma Developing: What to Watch For and How to Protect Your Vision

Glaucoma is a progressive eye condition. Early diagnosis and treatment are important in avoiding vision loss. This disease primarily affects the optic nerve, which transfers visual signals from the eye to the brain. Recognizing the early signs of glaucoma can make a significant difference, as a timely intervention may help prevent severe vision loss. At Seton Eye Clinic, eye health specialists emphasize the significance of routine eye exams to catch these signs early, especially for those at risk.

Understanding Glaucoma: What Is It and Who Is at Risk?

Glaucoma is a group of eye conditions typically linked to high intraocular pressure (IOP). Elevated IOP can damage the optic nerve over time, leading to vision loss. Primary open-angle glaucoma is among the most common type of glaucoma. This type progresses slowly, often without symptoms in the initial stages. Narrow-angle or acute glaucoma, however, can come on suddenly, causing immediate symptoms and requiring urgent care.

While anyone can develop glaucoma, some groups are at a higher risk:

• Older Adults: Glaucoma risk increases with age, especially after 60.
• Family History: Individuals with a family background of glaucoma have a higher chance of experiencing the condition.
• Ethnicity: African Americans, Hispanics, and Asians have a higher risk of certain types of glaucoma.
• Medical Conditions: People having diabetes, high blood pressure, or heart disease are at increased risk.

Early Signs and Symptoms of Glaucoma

Early glaucoma symptoms can be easy to overlook, as they often develop gradually and are painless. However, knowing what to look for can make a difference in early detection:

1. Gradual Vision Loss: One of the earliest signs is a slow loss of peripheral vision, which can often go unnoticed as central vision remains unaffected.
2. Halos Around Lights: Some individuals report seeing halos or rings around lights, particularly in low-light conditions.
3. Eye Redness or Irritation: Chronic redness or discomfort in the eye can sometimes be associated with elevated pressure.
4. Headaches or Eye Pain: Pressure buildup can sometimes lead to headaches, particularly around the brow area.

These symptoms are not exclusive to glaucoma but should prompt an eye examination. Detecting glaucoma at a much earlier stage allows patients to begin managing the condition before vision loss progresses.

The Role of Regular Eye Exams

Regular eye examinations are crucial for identifying glaucoma, especially since it is often asymptomatic in its early stages. Comprehensive eye exams can identify high IOP and optic nerve abnormalities that may indicate glaucoma, even if no symptoms are present.

• Visual Field Test: This test assesses peripheral vision and can detect any vision loss patterns associated with glaucoma.
• Optic Nerve Imaging: Imaging techniques like OCT (Optical Coherence Tomography) allow optometrists to view detailed optic nerve images and check for early signs of damage.
• Intraocular Pressure Test: Measuring IOP is a primary way to identify glaucoma risk, as elevated pressure is a major contributing factor.

If you’re at higher risk or have any symptoms, scheduling a glaucoma evaluation in Calgary can be essential in catching the disease early and preserving your vision.

Treatment Options for Managing Glaucoma

While glaucoma cannot be cured, treatment can slow its progression. Various treatments can help control eye pressure and protect vision depending on the stage and type of glaucoma.

1. Medications

Eye drops are often the first line of treatment for glaucoma, helping to reduce intraocular pressure by improving fluid drainage or reducing fluid production in the eye. Some common types of eye drops for glaucoma include:

• Prostaglandins: These increase fluid outflow, reducing pressure in the eye.
• Beta Blockers: These reduce fluid production in the eye.
• Carbonic Anhydrase Inhibitors: These are typically used when other medications are ineffective, also reducing fluid production.

2. Laser Treatment

Laser therapy can treat certain types of glaucoma by improving fluid drainage. It’s often a quick, in-office procedure with minimal discomfort.

• Laser Trabeculoplasty: Commonly used for open-angle glaucoma, this procedure improves fluid drainage from the eye.
• Laser Iridotomy: This procedure creates a small opening in the iris to help fluid move more freely. It is often used in narrow-angle glaucoma.

3. Surgery

When medications and laser treatments aren’t enough, surgery may be considered. Surgical options aim to create new drainage pathways, which help lower IOP. Types of surgery include:

• Trabeculectomy: A surgical procedure to make a new channel for fluid to drain, reducing pressure in the eye.
• Glaucoma Drainage Implants: Small devices are implanted to aid fluid drainage and are often used in advanced cases.

Discussing these options with an optometrist helps tailor the approach to your specific needs, as the best choice depends on the type and progression of glaucoma.

Lifestyle Changes to Support Eye Health

Although lifestyle changes cannot cure glaucoma, some adjustments may help manage eye pressure and promote overall eye health:

• Regular Exercise: Studies show moderate exercise, like walking or swimming, can reduce IOP and improve overall eye health. Individuals with a family background of glaucoma have a higher chance of experiencing the condition, significantly if they have advanced glaucoma.
• Hydration: Drinking water in small amounts throughout the day, rather than large amounts at once, helps maintain stable eye pressure.
• Limit Caffeine Intake: High caffeine intake can temporarily raise eye pressure, so limiting coffee or caffeinated drinks may be beneficial.
• Protect Your Eyes: Wearing sunglasses to reduce exposure to UV light, avoiding eye injuries, and using protective eyewear during activities can help support long-term eye health.

Importance of Early Detection and Ongoing Care

Because glaucoma progresses slowly, consistent monitoring is crucial. Ongoing care helps detect changes and adjust treatment as needed. Eye exams are essential for at-risk patients, as early intervention can slow the disease’s progression and preserve vision.

At Premier Eye Care—Seton, our team focuses on proactive eye health. Thorough examinations are conducted to identify early indicators of glaucoma and create customized treatment plans based on each patient’s needs. Regular visits help ensure that any changes in eye health are addressed promptly, allowing for better management of this progressive condition.
