Vision loss due to glaucoma has traditionally been described as loss of “peripheral vision”. Nerve damage by glaucoma can be illustrated as causing “tunnel vision” or as if one is “looking through a straw” (Figure 1).
1. Let's talk about Glaucoma!
The month of January is Glaucoma Awareness Month Worldwide. So I thought it fitting to write my first blog of this year on this very common Eye Disease that affects an estimated 76 million persons worldwide
Have you ever heard of glaucoma? It may sound like a fancy word, but it's actually a very common serious condition as it is currently the leading cause of irreversible blindness worldwide. Glaucoma has earned the nickname "The Silent Thief of Sight" because it often goes unnoticed until it's too late. In this blog, we're going to dive into everything you need to know about glaucoma, from what it is, to how it's diagnosed, to the various treatment options available, including eye surgery. I promise I will keep it very simple. So, if you want to protect your precious eyes, keep reading!
2. What exactly is Glaucoma and why is it such a sneaky thief?
Glaucoma is a sneaky thief that can snatch your sight without warning. So, let me break it down for you. Glaucoma is an eye disease that causes increased pressure in the eyes that damages the optic nerve; which is responsible for transmitting visual information to your brain. Now, here's the kicker - most types of glaucoma have no noticeable symptoms in the early stages. You could have glaucoma and not even know it. That's why it's crucial to get regular eye exams, especially if you're over 40 or have a family history of the condition. Don't let this silent thief rob you of your vision.
3. Don't wait until it's too late! Early signs and symptoms of Glaucoma
When it comes to Glaucoma, you can't afford to wait until it's too late. You need to be aware of the early signs and symptoms that could indicate this sneaky thief is at work.
Now, here's the thing - as I mentioned before, most types of glaucoma don't show any noticeable symptoms in the early stages. But that doesn't mean you're completely out of luck. There are a few signs that you should be on the lookout for.
First off, if you start noticing frequent changes in your vision - like blurriness or a loss of peripheral vision - it's time to pay attention. Especially if you're constantly seeing halos around lights or experiencing eye pain or redness.
Remember, prevention is key. So stay tuned for the next section where we'll dive into how glaucoma is diagnosed and the treatment options available.
4. Getting diagnosed: What to expect during your Glaucoma eye exam
If you suspect you may have this sneaky thief of sight, it's crucial to schedule an eye exam as soon as possible. Don't wait around, thinking it will just go away on its own, because it won't.
During your glaucoma eye exam, your eye doctor will conduct a series of tests to evaluate the health of your eyes and assess any potential damage caused by glaucoma. These tests may include measuring your eye pressure, examining your optic nerve with a fundus camera or OCT scan, and checking your peripheral vision with a visual field test.
Now, I know what you're thinking. Eye exams can be uncomfortable and even a little scary. But trust me, it's worth it. Early detection is key to preventing further damage and preserving your precious vision.
5. Treatment options that can help save your vision
Once you've been diagnosed with glaucoma, your eye doctor will work with you to create a personalised treatment plan.
One of the main goals of glaucoma treatment is to lower the pressure inside your eyes, as high eye pressure is a major risk factor for optic nerve damage. Your doctor may start by prescribing eye drops that help reduce eye pressure. These drops need to be used regularly, as directed, to effectively manage glaucoma.
In some cases, surgeries may be recommended to further control eye pressure and prevent further damage. It's important to remember that glaucoma treatment is a lifelong commitment, and regular follow-up appointments with your eye doctor are crucial to monitor the progression of the disease and adjust your treatment plan if needed.
6. Tips for preventing Glaucoma and protecting your sight
While there's no guaranteed way to prevent glaucoma, there are certain steps you can take to reduce your risk and protect your precious sight:
1. Regular Eye Exams: Schedule regular eye exams, especially if you have a family history of glaucoma or other risk factors. Early detection is key in effectively managing this sneaky thief of sight.
2. Know Your Risks: Understand the risk factors associated with glaucoma and take appropriate action. Some common risk factors include age, family history, high eye pressure, and certain medical conditions like diabetes or hypertension.
3. Be Aware of Your Eye Health: Pay attention to any changes in your vision or eye health and report them to your eye doctor promptly. Ignoring these signs can lead to delayed diagnosis and potential vision loss.
4. Take Your Meds: If you've been diagnosed with glaucoma and prescribed eye drops, consistently follow your doctor's instructions and take them as directed. Skipping doses may compromise the effectiveness of your treatment.
5. Embrace a Healthy Lifestyle: A healthy lifestyle can go a long way in reducing your risk of developing glaucoma. Eat a balanced diet, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol consumption.
Remember, my friends, it's always better to be proactive than reactive when it comes to your eye health. By implementing these simple steps into your routine, you'll be taking major strides in protecting your sight and keeping glaucoma at bay.
