January is Glaucoma Awareness Month, a time dedicated to raising awareness about one of the leading causes of irreversible blindness worldwide. In South Africa, the impact of glaucoma is significant, with an estimated 5% of people over the age of 40 affected by this silent vision thief. Early detection and treatment are crucial to preserving vision, making regular eye exams a vital step in safeguarding your sight.
What is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, which is essential for clear vision. This damage is often caused by abnormally high pressure in the eye, but it can also occur with normal eye pressure. Glaucoma progresses gradually, and symptoms may not appear until significant vision loss has occurred, earning it the nickname “the silent thief of sight.”
Who is at Risk?
While anyone can develop glaucoma, certain factors increase the risk:
- Age: People over 40 are more susceptible.
- Family history: Genetics plays a significant role.
- Medical conditions: Diabetes, high blood pressure, and other vascular conditions.
- Eye injuries: Previous trauma to the eye can increase the likelihood.
- Race: Studies show that people of African descent are at higher risk.
Symptoms to Watch For
Glaucoma symptoms often vary depending on the type and stage of the disease:
- Open-Angle Glaucoma (most common): Gradual loss of peripheral vision, often unnoticed until advanced stages.
- Angle-Closure Glaucoma: Sudden eye pain, headaches, nausea, blurry vision, and halos around lights. This is a medical emergency.
- Normal-Tension Glaucoma: Optic nerve damage despite normal eye pressure, often detected only during an eye exam.
Treatment Options
While there is no cure for glaucoma, early treatment can slow or prevent further vision loss. Treatment options include:
- Medications: Eye drops to reduce eye pressure.
- Laser therapy: Improves drainage of eye fluid.
- Surgery: Creates a new drainage channel or implants devices to lower eye pressure.
Why Regular Eye Exams Matter
Regular eye exams are the most effective way to detect glaucoma early, especially since it often shows no symptoms. Optic Edge Optometrists recommend a comprehensive eye exam every 1-2 years for most adults, and annually for those at higher risk. These exams include:
- Intraocular Pressure Test: Measures eye pressure.
- Optic Nerve Assessment: Evaluates the health of the optic nerve.
- Visual Field Test: Detects peripheral vision loss.
