Macular Degeneration

Concerned About Macular Degeneration? – Here Are 6 Tips to Lower your Risk

What Is Macular Degeneration?

Age-related macular degeneration (AMD) is a deterioration of the macula, the key part of the retina responsible for highly detailed vision and central vision. There are two main types of macular degeneration: dry and wet.

Dry AMD occurs when small deposits in the macula called drusen gradually damage the light-sensitive retinal nerve cells, leading to vision loss.

In wet AMD, fragile new blood vessels grow under the macula. When these blood vessels leak blood or fluid, it damages the macula. Although both types of macular degeneration can result in vision loss, wet AMD is the more serious form of the disease as it results in faster and greater vision loss.

Who Is At High Risk for Macular Degeneration?

  • age 50+
  • a diet high in saturated fat
  • Smoking
  • High blood pressure
  • Obesity
  • Family history of AMD
  • Cardiovascular disease

6 Ways to Reduce Your Risk of Macular Degeneration

The following have been shown to lower the risk of developing AMD:

Stop smoking

If you don’t smoke, don’t start, and if you smoke—quit. Smokers are 4 times more at risk of developing AMD and typically develop the disease around 10 years earlier than non-smokers.

Wear Quality Sunglasses

UV rays from sunlight can put your eyes at risk. So make sure you choose high-quality 100% UVA & UBV filtering sunglasses to block the sun’s harmful UV rays. Consider getting polarized lenses, as they filter out reflected light rays more efficiently. That’s especially important if you spend time on the water, at the beach, in the snow or driving.

Check Your Blood Pressure

High blood pressure not only harms your heart, but restricts oxygenated blood from reaching your eyes. Have your blood pressure checked regularly. If you already have hypertension, consider using an at-home monitor to keep tabs on it.

Eat Healthy and Consider Supplements

Cut out saturated fat, which can raise your blood pressure. Eat fewer animal fats and replace butter with olive oil. Look for plant-based, high-protein alternatives to meat, and eat oily fish like sardines, mackerel and salmon.

Dark, leafy greens are terrific for your eyes. Kale and other greens are full of lutein and zeaxanthin, antioxidants that promote eye health. If you have dry AMD, ask your optometrist about antioxidant supplements that can slow AMD’s progression.

Know Your Family History

Up to 70% of AMD cases have a genetic component. People with a parent or sibling with AMD have a greater risk of developing this serious sight-threatening eye disease. If you have a family history of this disease, get your eyes frequent eye tested for AMD.

Get Your Eyes Checked Regularly

Everyone should have regular comprehensive eye exams, especially if you’re over 50, have a family history of AMD, hypertension or other risk factors.

An eye exam that screens for AMD typically includes:

  • Visual Acuity – tests your ability to read and see an eye chart from various distances
  • Pupil Dilation – the optometrist applies eye drops to dilate the pupil so they can examine the inside of your eyes
  • Digital Retina Image and/or OCT – full color 3D imaging of the macula to detect leakage from the vessels and measure retinal thickness. This can help the eye doctor diagnose wet AMD, even in the early phases.
  • Amsler Grid – The optometrist asks the patient how straight lines on a checkerboard grid appear. The answer “wavy” or “missing” could indicate the presence dry or wet AMD.

Your vision is your gateway to the world. Good vision lets you live an active and independent life, even in your advanced years. Regardless of your age, get your eyes checked regularly, and all the more frequently if you have a family history of AMD or other risk factors.

FAQ

What percentage of the population has macular degeneration?

An estimated 8.7% of the global population has macular degeneration. This number is expected to increase from the current 196 million people affected to 288 million by 2040.

Do injections work for wet macular degeneration?

When AMD has progressed to the “wet” phase, anti-VEGF injections can preserve remaining vision by reducing fluid leakage and bleeding from the macular blood vessels.

Childhood Myopia Global Crisis!

What Is Myopia?

Myopia occurs when the eye elongates, causing light rays to focus in front of the light-sensitive retina rather than directly on it, while looking at something far away. So, people with nearsightedness perceive distant objects as blurred while close-up objects can remain clear.

Myopia tends to develop during childhood, when the eyeballs rapidly grow (along with the rest of the body), mainly between the ages of 8-18. It can worsen slowly or quickly, but it is not simply an inconvenience. People with progressive myopia are more likely to develop serious eye disease like cataracts, retinal detachment, macular degeneration and glaucoma later in life—conditions which may lead to permanent loss of vision and even blindness.

How To Know Whether Your Child Is Myopic

When it comes to the prevalence of myopia (nearsightedness), the statistics are staggering. By 2050, nearly half of the world’s population—about 5 billion people—will be myopic. Below are a few useful tips to help you prevent your child from being part of that statistic.

Below are some telltale signs to watch for

  • Blurred distance vision – Objects in the distance are blurred; kids may complain that they can’t see the board
  • Headaches – When myopia isn’t corrected, it can cause eye strain and headaches.
  • Head tilting or squinting – If your child squints or tilts his or her head while watching TV, for example, it may be a symptom of myopia.
  • Looking at objects too closely – If you notice your child moving closer to the TV or squinting as they try to see the writing on the board, it may indicate myopia.

What Parents Can Do to Slow Their Child’s Myopia Progression

  • Encourage your child to go outdoors for at least 90 minutes a day, preferably in the sunshine. Studies show that playing outdoors reduces the risk of developing myopia and slows its progression.
  • Limit the amount of time your child spends staring at a screen, reading and doing close work such as homework.
  • When your child uses a digital screen, make sure that it isn’t too close to the face.
  • Teach the 20-20-20 rule: During screen time, take a break every 20 minutes to look at an object across the room or out the window about 20 feet away, for at least 20 seconds.

How We Can Help

Certain eye doctors offer treatment methods known as myopia control or myopia management. These include orthokeratology, bifocal or multifocal contact lenses, and eye drops like low dose atropine. Regular eyeglasses and contact lenses don’t prevent its progression but do correct myopia so the child can see and function normally.

If your child shows signs of myopia, schedule an eye exam with Riz Eye Care in Sugar Land as soon as possible.

How is myopia diagnosed?

Your child’s eye doctor will perform a thorough pediatric eye exam to diagnose myopia, which often includes a visual acuity test, where the eye doctor will use an eye chart made up of letters of varied sizes. If the test results indicate myopia, then the optometrist may shine a light into their eyes and evaluate the reflection off the retina to determine the degree of refractive error for their prescription.

Can myopia lead to blindness?

High myopia may increase your child’s risk of developing more serious eye conditions later in life, such as cataracts, retinal detachment and glaucoma. Left untreated, high myopia complications can sometimes lead to blindness—which is why routine eye exams are critical.

Why Are Dilated Eye Exams So Important?

Having your eyes dilated during an eye exam may seem like a nuisance. But when you consider the benefits of a dilated eye exam, the temporary blurred vision and sensitivity to light that typically follow are definitely worth it.

What Are Dilated Eye Exams?

At some point during a comprehensive eye exam, your optometrist will shine a bright light into your eyes to examine the back of your eye, called the retina. The problem is that bright light causes the size of the pupil’s opening to shrink, which makes it hard for the optometrist to see a large portion of the retina.

That’s why eye doctors apply special eye drops in each eye to keep the pupils open. A dilated pupil allows for a much more accurate assessment of your eye’s structures, including the focusing lens, blood vessels and tissues at the back of the eye called the retina, as well as the optic nerve and macula.

Dilating the eyes makes it easier for your optometrist to detect the following conditions and diseases:

It’s important to note that many of these conditions can develop without noticeable symptoms, until they cause vision loss at which point treatment may be more challenging, making dilated eye exams all the more crucial.

The Dilation Process

First, your eye doctor will apply eye drops to each eye to trigger dilation of the pupil. Your eyes should be fully dilated about 10-20 minutes later.

Your eyes will remain dilated for 4-6 hours, and during this time you may be sensitive to light. That’s because the larger pupil allows more light than usual to enter the eye. Many patients find it more comfortable to wear sunglasses until their eyes return to normal.

Reading and using a computer may be difficult with dilated eyes, and your vision may be blurred. Some patients report feeling a tightening sensation in their eyelids, or headaches.

Dilated eye exams are a crucial part of keeping your eyes healthy. To schedule your comprehensive eye exam, call Riz Eye Care in Houston today!

At what age should one have a dilated eye exam?

You should have your dilated eye exam no matter your age. Most eye doctors will dilate a new patient at their first exam regardless of age to get a baseline of their retinal health.

Will I be able to return to work after a dilated eye exam?

Everyone reacts differently, so it’s hard to tell. If your job requires you to focus on small print or detail, it may be challenging. Typing and writing may also be difficult with dilated pupils. To be on the safe side, book your appointment at the end of your work day, clear your schedule after your eye exam and only plan to do activities which aren’t visually demanding.
