Knowledge is power. The proverb attributed to Sir Francis Bacon (although it’s also said to be found in Sanskrit) possibly offers one of the most powerful tools for managing chronic health conditions. So it makes sense that patients who understand their condition and their prescribed care plans are more likely to manage their health proactively.
Conversely, if a patient misunderstands their condition, it can result in non-compliance with medical recommendations, significantly and adversely affecting outcomes. Therefore, having access to reliable, evidence-based information is crucial. While the internet provides unlimited access to a staggering amount of information, not all information found online is trustworthy or helpful.
The estimated 80 million people living with glaucoma worldwide, including more than three million Americans, are important stakeholders in their treatment. With the correct information, they can significantly impact the success of their medical outcomes. But unfortunately, there are many misconceptions about the disease that can leave you misinformed. We’ve debunked nine of the most common glaucoma myths.
There is currently no cure for glaucoma. However, doctors can effectively use surgical procedures and other treatments to prevent or slow further damage from occurring. In addition, surgery may be recommended when medicines and laser treatments fail.
There are a few different types of surgery for glaucoma that can help lower the pressure in your eye:
This procedure is usually used to treat open-angle glaucoma and sometimes other kinds of glaucoma, such as angle-closure. The surgeon will create a tiny opening in the top of your eye, under your eyelid, where no one will see it. This opening allows extra fluid in your eye to drain away, lowering the pressure in your eye.
Glaucoma Implant Surgery
Glaucoma implant surgery is used to treat several types of glaucoma, including congenital glaucoma, neovascular glaucoma, and glaucoma caused by an injury. A tiny tube, or shunt, is implanted onto the white of your eye to help extra fluid drain out of your eye, lowering your eye pressure.
Minimally Invasive Glaucoma Surgery (MIGS)
MIGS is a group of treatments recently developed that use microscopic-sized equipment and tiny incisions to reduce the complications associated with standard glaucoma surgeries.
Most types of glaucoma will not have any symptoms, and people with good vision may not notice any symptoms until the late stages, which is why glaucoma is called the “silent thief of sight.” The later the disease is diagnosed and treated, the more likely it is that noticeable vision loss may occur.
While glaucoma can be hereditary, many glaucoma patients without a family history of the condition are diagnosed with glaucoma. There’s also the possibility that family members did have the disease but were never examined adequately for glaucoma. That’s why all patients diagnosed with glaucoma should make sure their family members are examined for it.
Glaucoma does not lead to vision loss for most people. Frequent eye exams are the key to early diagnosis, increasing a person’s chances of maintaining good eyesight and leading a healthy lifestyle. With modern treatment, glaucoma is controllable.
There are multiple tests for glaucoma because doctors look at many factors, all of them painless. The two most common tests are tonometry and ophthalmoscopy.
Tonometry measures the pressure within a person’s eye. First, eye drops numb the eye, then a doctor or technician uses a small device called a tonometer pressed briefly against the cornea to measure the inner pressure of the eye. Another type of tonometer not requiring drops uses a puff of air applied to the cornea to measure the pressure of the eye.
Ophthalmoscopy is a diagnostic procedure to examine a person’s optic nerve for glaucoma damage. First, the pupil is dilated with eye drops so that the doctor can see through the eye to examine the shape and color of the optic nerve. Then, the doctor will use a small device with a light on the end to light and magnify the optic nerve. The doctor may request additional tests in cases where a person’s intraocular pressure (IOP) is not within the normal range or the optic nerve looks unusual.
While glaucoma is not curable, it is highly treatable. Many effective treatments are available, including eye drop medications, injectable medications, oral medicines, and laser and surgical procedures to help halt glaucoma progression. Treatment helps fluid flow properly out of the eye, reducing pressure inside the eye and decreasing damage to the optic nerve, preserving your existing vision. In addition, treatment for glaucoma prevents it from causing damage to the optic nerve, which can lead to blindness.
Although people over 60 are at a greater risk of developing glaucoma than people in their 40s, certain types of glaucoma can affect people aged 20 to 50 and even young children and infants (due to abnormal ocular development).
A person can’t reverse glaucoma’s damage by adopting a healthier lifestyle; however, some lifestyle changes can help prevent further damage. There are several evidence-based recommendations for physical fitness, diet, and other lifestyle modifications beneficial for patients with glaucoma. Combined with regular eye exams and following the prescribed treatment from your doctor, a healthy lifestyle can certainly help.
Glaucoma is known to silently creep up and slowly damage the eyesight of a person. The symptoms of open-angle glaucoma, the most common form of glaucoma, are not quite noticeable at first. So, people with apparently perfect vision may have glaucoma and yet be unaware of it. However, once the damage becomes extensive, symptoms eventually show up. That’s why it’s so critical to have regular eye exams.
Glaucoma is the second leading cause of blindness in the world, according to the World Health Organization. In the United States, more than 120,000 people are blind from glaucoma, accounting for nine to twelve percent of all cases of blindness. Because symptoms often don’t become noticeable until the disease is advanced, only about half of those with glaucoma even are aware they have it.
Debunking myths and having the facts about glaucoma is essential to protect and preserve eye health.
