Preventing Vision Loss: The Importance of Glaucoma Eye Care

Have you ever wondered why eye care professionals stress the importance of regular glaucoma eye exams? Glaucoma, a major cause of blindness, often shows no symptoms until significant damage has occurred. 

To enlighten you on this eye condition, we provide guidance on the subtle signs of glaucoma. We also emphasize the necessity of consistent eye check-ups and highlight the key risk factors involved.

At Premier Medical Eye Group in Mobile, we offer proactive eye health management. We ensure you receive the highest standard of care to safeguard your vision.

What is Glaucoma?

Glaucoma is a group of eye conditions that damage the optic nerve, which is responsible for interpreting visual input. High intraocular pressure (IOP) often causes it. Glaucoma is a leading cause of blindness for people over 60.  However, with early detection and proper management, including glaucoma medication and potential glaucoma surgery, vision loss can often be prevented or minimized.

Types of Glaucoma

1. Open-Angle Glaucoma: This is the most common form of the disease. It occurs when the eye's drainage canals become clogged over time. This prevents the proper outflow of aqueous humor (the fluid inside the eye).    
2. Angle-Closure Glaucoma: Also known as closed-angle glaucoma. This type occurs when the iris is very close to the drainage angle in the eye, blocking the exit of eye fluid. This condition can present suddenly and is a medical emergency.
3. Normal-Tension Glaucoma: Optic nerve damage occurs even though intraocular pressure is within normal ranges. This indicates that, besides eye pressure, factors such as a fragile optic nerve or reduced blood supply to the optic nerve also contribute. 
4. Secondary Glaucoma: This type results from another medical condition or injury that affects the eye's ability to drain fluid properly. Conditions such as inflammation, trauma, or the use of certain medications like steroids can lead to this type.

Signs and Symptoms of Glaucoma

Glaucoma symptoms usually become apparent in the late stages of the disease, when your eyesight is already compromised. Common signs of glaucoma include: 

• Peripheral Vision Loss: Often one of the first signs, individuals may notice a gradual loss of peripheral or side vision.
• Tunnel Vision: In advanced stages, patients may experience tunnel vision.
• Eye Pain: Sudden and severe eye pain can occur, especially in acute angle-closure glaucoma.
• Red Eyes: Redness in the eyes may accompany other symptoms.
• Halos Around Lights: Seeing halos around lights, especially at night, can be a symptom.
• Nausea and Vomiting: These can accompany severe eye pain and vision disturbances.

Who is at Risk for Glaucoma?

Certain factors increase the risk of developing glaucoma:

• Age: Individuals over 60 are at higher risk.
• Family History: A family history of glaucoma increases your risk.
• Medical Conditions: Diabetes, high blood pressure, and heart disease can elevate the risk.
• Eye Conditions: Severe myopia (nearsightedness) or a history of eye injuries can increase risk.
• Race: African Americans over age 40 and people of Hispanic and Asian descent have a higher risk.

Why Regular Eye Exams are Critical

Regular eye exams are the cornerstone of glaucoma management and prevention. Here’s why they are essential:

• Early Detection: Glaucoma can be detected before any noticeable vision loss occurs. This is key because damage from glaucoma is irreversible.
• Monitoring Progression: Medical eye exams help our eye care clinic monitor the progression and effectiveness of treatment for those diagnosed with glaucoma. 
• Preventing Vision Loss: Early and consistent eye disease management can slow or prevent further vision loss. A low-vision clinic can also provide aids and tools to enhance your remaining vision.

How Often Do You Need an Eye Exam?

The frequency of eye exams depends on several factors. This includes whether your eye doctor has diagnosed you with glaucoma and other eye conditions.  Your glaucoma eye doctor will be able to advise.

• Ages 20-39: Every 5-10 years if you are at low risk
• Ages 40-54: Every 2-4 years
• Ages 55-64: Every 1-3 years
• Ages 65 and older: Every 1-2 years
