Rarely Known Facts About Eye Diseases

Have you ever wondered what can make you happy? Maybe gathering with loved ones, seeing the beauty of nature while traveling, enjoying culinary tours with friends, attending concerts or other exciting shows, and much more. But imagine if your vision were impaired due to an eye disease, and you couldn't enjoy any of these experiences. Happiness would vanish, wouldn't it?

It's unfortunate how most people consider eye health something trivial, only to realize the importance when they begin experiencing vision problems. Many eye diseases, like cataracts, glaucoma, and macular degeneration, often don’t show symptoms in the early stages. This is why these diseases are often referred to as the "silent thief of sight."

One of the main reasons eye diseases are often neglected is the lack of understanding about the importance of regular eye check-ups. Most people only visit an eye doctor when symptoms become severe, such as blurry vision or pain. In fact, early detection is crucial to prevent permanent damage to the eyes.

Furthermore, modern lifestyles with excessive exposure to digital screens have increased the risk of eye diseases, especially dry eye syndrome. Many people mistake this for regular tiredness, but if left untreated, it can develop into a chronic issue that affects one's quality of life.

Changes in climate and environmental factors, such as air pollution, also contribute to deteriorating eye health. Tiny particles in polluted air can irritate the eye’s surface and increase the risk of chronic eye diseases like conjunctivitis. While wearing protective eyewear, like sunglasses, when outdoors can help shield the eyes from pollutants, the risk of eye disease still affects everyone.

One interesting fact about the eyes that you may not know is that the human eye consists of more than two million parts working harmoniously to provide perfect vision. Imagine how intricate and complex this vital organ is.

This complexity makes the eyes vulnerable to various diseases. One such condition is keratoconus, where the cornea becomes thin and cone-shaped, leading to blurry vision and light sensitivity. This eye disease is often misdiagnosed as regular nearsightedness.

Another lesser-known eye disease is Charles Bonnet syndrome, where people who experience vision loss suffer from visual hallucinations. Although it sounds scary, this is not a sign of mental disorder, but rather the brain’s response to lack of visual stimuli. This condition illustrates the complex relationship between the eyes and the brain.

There is also a condition called uveitis, which is inflammation of the middle layer of the eye. The cause is often unknown but may be linked to autoimmune disorders or infections. If not treated, uveitis can lead to serious complications such as glaucoma or cataracts. Interestingly, uveitis occurs more frequently in younger individuals than in the elderly.

The World Health Organization (WHO) has revealed in its research that excessive exposure to ultraviolet (UV) rays can cause damage to the lens and retina, increasing the risk of eye diseases like cataracts and macular degeneration. Wearing sunglasses with UV protection is a simple yet effective step to prevent these harmful effects.

Additionally, there are eye diseases caused by genetic factors. For example, closed-angle glaucoma is more commonly found in the Asian population and has a strong genetic component. Early detection through intraocular pressure tests can help prevent vision loss due to glaucoma.

Not only genetics, but psychological factors like chronic stress can also affect eye health. Some studies show that stress can trigger an increase in intraocular pressure, leading to a condition called glaucoma. This shows that maintaining mental balance also impacts eye health.

Some eye diseases are linked to overall health conditions, such as diabetes. Diabetic retinopathy, for example, is a serious complication that can cause blindness if blood sugar levels are not controlled. Therefore, maintaining overall body health also directly impacts eye health.

Be thankful if you still have healthy eyes and have not experienced any significant eye issues. To keep them healthy, regular check-ups and a combination of a healthy lifestyle are key. Eating foods rich in vitamins A, C, and E, as well as omega-3, can help maintain eye health. Green vegetables like spinach and kale, and fatty fish like salmon, are excellent sources of nutrients for the eyes.

In addition to diet, getting enough rest for your eyes is crucial. Using the 20-20-20 method can help reduce eye fatigue from digital screens. Every 20 minutes, look at something 20 feet away for 20 seconds. This simple habit can prevent dry eye syndrome and other eye conditions that are often overlooked.

For those already at high risk, such as individuals with diabetes, hypertension, or a family history of eye diseases, managing these underlying conditions is essential to prevent complications in the eyes. For example, diabetic retinopathy can be prevented by keeping blood sugar levels stable and regularly checking the eyes.

There is still a significant need for education and raising awareness about the importance of eye health, especially understanding the risks of blue light exposure from digital devices, UV rays, lifestyle factors, and the importance of using screen protectors or anti-blue light glasses to reduce the long-term effects of digital screen use.

Education on natural foods that can protect the eyes has also become more relevant. For instance, compounds like lutein and zeaxanthin found in green vegetables like kale and spinach have been shown to protect the retina from damage caused by free radicals.

Regular eye exams can help prevent serious eye diseases. But you may not be sure when it’s truly necessary to see an ophthalmologist for a check-up.

Ideally, after the age of 20-30, you should start having regular eye exams, even if you feel that you have good vision and healthy eyes. Ask your eye doctor about how often you should have exams, especially if you have a family history of eye diseases or diabetes.

For adults in their 40s, comprehensive eye exams become more important, as this is when early signs of eye disease or changes in vision begin to appear. It's crucial to detect eye diseases early. Identifying and treating eye problems early can help preserve your vision.

However, if you experience issues like blurred vision, injury, eye pain, seeing floaters, or sudden flashes of light, you should see an eye doctor immediately. Similarly, if you wear lenses, visit your eye doctor every year to prevent eye diseases.

In modern medicine, the treatment of eye diseases has advanced significantly. For example, cataract surgery now uses advanced technology that allows for a quick, painless lens replacement. With this development, cataract patients can regain clear vision just days after the procedure.

For glaucoma, treatment typically involves eye drops designed to lower intraocular pressure. However, in more severe cases, doctors may recommend surgical procedures such as trabeculectomy or drainage implant surgery to reduce pressure.

Laser treatment has also become a standard approach for treating several other eye diseases. For example, diabetic retinopathy can be treated with laser photocoagulation, where laser light is used to seal leaking blood vessels in the retina. This method has proven effective in preventing blindness in many patients.

In addition, emerging technologies like gene therapy are being explored to treat genetic disorders that cause blindness, such as retinitis pigmentosa. Gene therapy offers new hope for patients with rare eye diseases who previously had no treatment options.

Visual aids also provide solutions for those with severe vision impairment. Specialized contact lenses, like scleral lenses, can help patients with keratoconus achieve better vision. Additionally, tools like digital screen readers have been designed to help those with severe vision impairment remain productive.

Don't hesitate to check your eye health, especially if you have recurring issues. Schedule an appointment with an ophthalmologist at IHH Healthcare Malaysia for early diagnosis and the best treatment options for any existing or potential eye problems. Book an appointment today!
