See Clearly, Protect Your Sight: Understanding Glaucoma

The month of March marks Glaucoma Awareness Month around the globe, a crucial time to shine a light on this leading cause of irreversible blindness worldwide. The objective is to raise awareness and promote glaucoma screenings around the world. It's important to remember that glaucoma isn't just an old person's disease - anyone can be affected by it, and early detection and treatment are the keys to preserving your vision and maintaining quality of life.

What is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, the crucial connection between your eye and brain responsible for transmitting visual information. This damage is often caused by increased pressure within the eye, which can occur due to a buildup of fluid called aqueous humor. Unfortunately, the initial stages of glaucoma often go unnoticed, earning it the nickname "the silent thief of sight."

Symptoms and Diagnosis:

Glaucoma is often symptomless in its early stages, making regular eye examinations critical for early detection and treatment. However, some individuals may experience symptoms in later stages, including:

• Blurred vision, particularly in peripheral (side) vision
• Tunnel vision
• Seeing halos around light
• Sudden eye pain and redness (although this is uncommon)

Early detection is crucial as vision loss caused by glaucoma is irreversible. During a comprehensive eye test at your local Spec-Savers, your optometrist will use various tools and techniques to assess your risk factors and check for signs of glaucoma.

This may include:

• Tonometry: Measures the pressure inside your eye.
• Ophthalmoscopy: Examines the back of your eye, including the optic nerve.
• Visual field testing: Evaluates your peripheral vision.

Treatment and Prevention:

While there's no cure for glaucoma, early diagnosis and treatment can significantly slow down its progression and preserve your vision. Treatment options vary depending on the type and severity of your case and may include:

• Eye drops: These medications decrease the production of aqueous humor or improve its drainage, lowering eye pressure.
• Laser treatment: This creates tiny channels in the eye to improve fluid drainage.
• Surgery: In some cases, surgery may be necessary to create a new drainage channel or alter existing channels.

While you cannot entirely prevent glaucoma, certain lifestyle factors can help lower your risk:

• Maintain a healthy weight: Studies suggest a connection between obesity and increased risk of glaucoma.
• Exercise regularly: Regular physical activity can improve blood flow and potentially lower eye pressure.
• Eat a balanced diet: Include plenty of fruits and vegetables rich in antioxidants, such as those found in our autumn.
• Manage stress effectively: Chronic stress can contribute to various health issues, including eye problems.
• Schedule regular eye tests: Spec-Savers recommends comprehensive eye exams every two years for adults aged 40 and over, and more frequently for those at higher risk.
• Know your family history:  Glaucoma is often hereditary.

This March, take action, and prioritise your eye health, schedule an appointment with your trusted Spec-Savers optometrist and get tested! Early detection and proper management of glaucoma can significantly impact your vision and well-being.
