What Can You Do About Floaters and Flashes in the Eye?

Flashes and floaters in the eye happen for many reasons, the most common being. Both flashes and floaters are generally harmless and do not require medical treatment. However, they may sometimes signal a retinal tear or detachment, which are conditions that can lead to vision loss if left untreated.

“Although very common, sudden onset of flashes and floaters should prompt a thorough peripheral retinal eye exam to be certain there is not a retinal tear or early retinal detachment,” explains Dr. Jose Martinez. “Both can be treated effectively but left untreated can lead to more serious sight-threatening problems.”

If you experience any of the following key warning signs of retinal tears or detachment, call your doctor right away:

  • A new onset of floaters and flashes of light in the eye
  • Gradual shading of vision from one side (like a curtain being drawn)
  • Rapid decline in sharp, central vision

What are eye floaters?

Eye floaters are spots in your vision that occur because the jelly-like substance (vitreous) inside your eyes becomes more liquid. As a result, microscopic fibers clump together and cast tiny shadows on your retina.

What are eye flashes?

Flashes are common after an eye injury. Many people report having ‘flashing lights’ or ‘lightening streaks’ appear in their visual field. This happens when the vitreous gel inside your eye rubs or pulls on the retina. Flashes of light can persist for several weeks or months following an eye injury.

What can you do about flashes and floaters in the eye?

The easiest way to get rid of flashes and floaters in the eye, at least temporarily, is to move your eyes up and down (this is more effective than moving your eyes side to side). This movement shifts the fluid around in your eye and moves them out of your field of vision.

If your condition is more serious and your vision is impaired, your doctor may recommend surgery or laser treatments including:

  • Vitrectomy
    Vitrectomy is a surgery to remove some or all of the vitreous gel from the eye. Your physician will then replace this jelly-like substance with a synthetic substitute to help your eye maintain its shape.
  • Vitreolysis
    While less common, floaters can be broken apart using a laser treatment. During this procedure, a laser is aimed at the floaters and breaks them apart so they are no longer noticeable.

7 Best Foods for Healthy Eyes

Many people can enjoy an active life well into their golden years without ever experiencing vision loss. However, with age comes a higher risk of developing age-related eye diseases and conditions like: Age-related macular degeneration, cataract, diabetic eye disease, glaucoma, low vision and dry eye. While eye problems and eye diseases become more prevalent with age, many can be prevented.

7 best foods for healthy eyes

If you’d like to preserve and protect your eye health and vision as you age, try some of these delicious selections:

  1. Dark leafy greens
    Dark leafy greens like spinach and other foods rich in vitamin C, like sweet potatoes, kale, carrots, turnips, butternut squash and mustard greens may be helpful for slowing the progression of cataracts.
  2. Citrus fruits and berries
    Citrus fruits and other fruits rich in vitamin C like cantaloupe, strawberries, kiwi, mango, papaya may be helpful for maintaining connective retinal tissues that diabetic eye disease damages.
  3. Nuts and seeds
    Almonds, hazelnuts and peanuts, as well as other foods rich in vitamin E like avocados, spinach, broccoli, wheat germ and sunflower seeds, may help improve vision. In fact, when used in combination with vitamin B and DHA, vitamin E has shown to improve visual fields and retinal sensitivity in people with glaucoma.
  4. Fish
    Fish, particularly omega-3 rich fish oil, is known for reversing dry eye (including dry eye caused by prolonged or regular computer use). You’ll get the most beneficial levels of omega-3s when you try some of these tasty options: Tuna, salmon, trout, mackerel and sardines.
  5. Whole grains
    Whole grain foods like brown rice, oatmeal, whole wheat bread, pasta or crackers are high in vitamin E. This powerful antioxidant vitamin may help reduce your risk for age-related macular degeneration.
  6. Legumes
    Kidney beans, black-eyed peas and lentils are good sources of bioflavonoids and zinc, which can help protect the retina and lower the risk for developing macular degeneration and cataracts.

Common Symptoms of a Detached Retina

Are you noticing more “floaters,” or cobweb-like specks in your field of vision? Are you seeing flashes of light? These are a few symptoms of a retinal detachment, and it is a medical emergency. If not promptly treated, retinal detachment can cause permanent vision loss. If you’re having any symptoms of a retinal detachment, see an eye care professional immediately.

“Early detection of symptoms and seeking care promptly is of great benefit to the patient,” said Dr. Peter A. Nixon.

The retina is a key factor in your normal, healthy vision. This light-sensitive layer of tissue lines the inside of your eye and transmits visual messages through the optic nerve to your brain. When the retina detaches, it is pulled or lifted from its normal position.

Symptoms of a detached retina

You may be surprised to learn that retinal detachment is painless. However, warning signs almost always occur before detachment occurs or as it is progressing. These critical signs include:

  • Multiple floaters (tiny specks that seem to drift through your field of vision) suddenly appearing
  • Seeing flashes of light in one or both eyes (photopsia)
  • Experiencing blurred vision
  • Noticing a gradual reduction inside (peripheral) vision
  • Seeing a curtain-like shadow over your visual field

“Flashes and floaters can indicate a retinal tear or retinal detachment. The only way to establish the diagnosis is to be examined by your eye doctor,” explains Dr. Nixon. “Early detection of symptoms and prompt evaluation are very important in preventing loss of vision.”

Are you at risk for retinal detachment?

Although retinal detachment can happen at any age, it is more common in Caucasian men over age 40. You have a greater risk for retinal detachment if you:

  • Have had a retinal detachment in the other eye
  • Have a family history of the condition
  • Are extremely nearsighted
  • Have undergone cataract surgery
  • Have other eye diseases or disorders, such as degenerative myopia, retinoschisis, uveitis or lattice degeneration
  • Have had an eye injury

Diabetic Eye Disease Awareness Month

November is Diabetic Eye Disease Awareness Month, which helps raise awareness of diabetes and its negative effects on the eyes. Diabetes is the leading cause of new cases of blindness among adults, though anyone with diabetic eye disease is at risk for vision loss and blindness. The retina specialists at Austin Retina Associates encourage anyone suffering from diabetes to seek immediate treatment for any vision problems to avoid vision loss or blindness.

The importance of regular vision exams

Anyone with diabetes should get regular vision screenings to help protect his or her eyesight. While a routine exam cannot diagnose diabetic eye disease, it can help identify issues while they are still treatable. If your doctor notices any unusual changes in your vision, he may recommend a comprehensive dilated eye exam with an ophthalmologist or optometrist.

Common types of diabetic eye disease

People with diabetes are more likely to develop cataracts and glaucoma than those without diabetes, however, the primary vision problems caused by diabetes are:

  • Diabetic retinopathy
    Retinopathy is a general term that means the retina of the eye is damaged. Over time, diabetes can damage the blood vessels in the retina, causing them to leak blood and other fluids. The build-up of excess blood and fluid causes the retinal tissue to swell, which leads to clouded vision. While diabetic retinopathy cannot be cured, treatment options are available to help preserve vision and reduce the risk of vision loss.
  • Diabetic macular edema
    If left untreated, diabetic retinopathy can lead to diabetic macular edema (DME). DME is an accumulation of fluid in the macula, the functional center of the retina that controls our most detailed vision abilities. Treatment options are available to help stop and sometimes reverse vision loss.

How to avoid diabetic retinopathy and DME

If you are diabetic, Diabetic Eye Disease Awareness month is the perfect time start actively protecting your vision. Here are a few easy steps to help you get started:

  • Maintain good blood pressure and cholesterol through healthy diet and exercise.
  • Receive a comprehensive dilated eye exam at least once a year (or more often as directed by your doctor).
  • If you are pregnant and have been diagnosed with gestational diabetes, it is important to pay close attention to your blood glucose levels. Try eating a low sugar, low carb and high fiber diet.

For expert diabetic eye disease treatment in Austin, call Austin Retina Associates at 877-925-7649 to schedule an initial consultation.

What Is a Diabetic Eye Exam?

Diabetes is a disease that impairs the body’s ability to produce the insulin hormone and leads to elevated levels of glucose (sugar) in the blood. Chronically elevated blood sugar levels can increase your risk for an array of eye problems including blurry vision, cataracts, glaucoma and diabetic retinopathy.

Often, diabetes damages the small blood vessels in your retina, or the back of the eye. This condition is called diabetic retinopathy, the most common cause of vision loss among people with diabetes. Diabetic retinopathy develops when blood vessels in the eye are exposed to high blood glucose levels for a prolonged period of time. This weakens the walls of the blood vessels in the eyes. The longer a person has had diabetes and the greater his/her exposure to high blood glucose, the higher his/her risk of having this condition.

“Diabetic eye disease, when caught in time, is no longer a blinding condition. Nowadays, with early detection and prompt treatment, we can prevent vision loss and in some cases, are able to reverse some of the diabetic changes in the retina. But what we like to do, at Austin Retina, is help educate our patients on what diabetes is and how it affects their vision,” explains Dr. Robert W. Wong. “By working together with the primary care physician, endocrinologist and the patient themselves, we find strategies to improve blood sugar and blood pressure control. These two risk factors, among others, are things our patients have the ability to control. And with guidance, our goal is to keep them seeing well and living healthier lives.”

If you have been diagnosed with diabetes, it is important to get regular eye exams, so your doctor can detect problems like diabetic retinopathy early, preserve your eye health and protect your vision.

What is a diabetic eye exam?

Anyone with diabetes is encouraged to get regular eye exams. This allows your ophthalmologist to look for changes in the blood vessels of the retina that may indicate diabetic retinopathy. Here is what you can expect during a diabetic eye exam:

  • Your ophthalmologist will ask you about your medical and vision history.
  • Next, you will read an eye chart.
  • The doctor will then examine the retina in the back or your eye using an instrument called an ophthalmoscope.
  • Often, your doctor will administer drops to dilate your pupils and use a special light called a slit lamp to view the retina.
  • A test called fluorescein angiography may be used to reveal changes in the structure and function of the retinal blood vessels. For this test, your doctor will inject a fluorescent yellow dye into one of your veins and photograph your retina as the dye outlines the blood vessels.
  • During a diabetic eye exam, your doctor will also check your eyes for cataracts and glaucoma.

If you’ve been diagnosed with diabetic retinopathy, the experienced eye care specialists at Austin Retina Associates can help. We are skilled in the treatment of diabetic retinopathy in Austin. Call at 877-925-7649 to schedule an initial consultation.

August is Children’s Eye Health Month

It’s August, which means you’re likely to find many parents scouring online ads and store shelves for the best back to school deals on backpacks and lunch boxes. But it’s important to schedule a comprehensive eye exam for your kids, too. August is Children’s Eye Health Month, so start the year off right with healthy eyes and clear vision so they can whiz through their school day with ease.

Things to look for if you suspect vision troubles

Most pediatricians will begin routine eye exams during their annual well-child visits beginning at age three. If you or your doctor suspect vision problems or have other eye health concerns, they will recommend you visit an ophthalmologist for further testing. Amblyopia (lazy eye), Strabismus (crossed eyes), color blindness and refractive errors (nearsightedness, farsightedness, and astigmatism) are the most common conditions that can affect a child’s eyesight.

“It’s important that all children are screened by an eyecare professional by the age of 5,” explains Dr. Armitage Haprer. “In addition, if there’s a family history of any retinal disease, like retinoblastoma, Stickler’s disease, or Marfan’s Disease, then each child should be screened at birth.”

Here are some common things to watch for, so you’ll know if your child is struggling with their vision:

  • Frequent eye rubbing or squeezing
  • Squinting
  • Tilting or turning head to look at objects
  • Wandering eyes
  • Recurring headaches
  • Watery eyes or redness

Eye safety is just as important for protecting your child’s vision

Did you know that nearly 90 percent of eye injuries affecting children are avoidable? Here are some easy ways you can help protect their vision:

  • Children who play sports should wear eye protection with polycarbonate lenses, which are shatter-resistant.
  • Look for toys that are approved by The American Society for Testing and Materials (ASTM), which means they have met or exceeded national safety standards.
  • Avoid projectile toys like darts, bow and arrow or missile-firing toys.

If your child should experience an eye injury, do not allow them to touch or rub the affected eye and seek medical attention immediately. If your child is in need of specialist care or retinal surgery in Austin, call the experienced eye care specialists at Austin Retina Associates at 877-925-7649 to schedule an appointment.

What Does the Retina Do?

The retina is an essential part of the eye that enables vision. It’s a thin layer of tissue that covers approximately 65 percent of the back of the eye, near the optic nerve. Its job is to receive light from the lens, convert it to neural signals and transmit them to the brain for visual recognition.

Because the retina and optic nerve originate as outgrowths of the developing brain, they are both considered part of the central nervous system and brain tissue.

What is the primary function of the retina?

The eye has many parts that must work together in order to produce clear vision. The retina is made up of ten layers of cells that work together to detect light and turn it into electrical impulses. These special cells are called cones and rods and are known as photoreceptors:

  • Cones
    Cones are located in the central, or macula, part of the retina. These cells help detect color and detail. Similarly, the macula allows us to perform fine functions like reading, writing, typing and clearly recognizing people’s facial details (e.g., freckles).
  • Rods
    Rods are located in the peripheral, or outer, part of the retina. These cells allow us to see in poor lighting and provide us with night vision.

How can I tell if there is a problem with my retinas?

There are many ways to tell if you’re suffering from retinal damage, tears or detachment, including:

  • Sudden onset of floaters (small to large dark spots blocking your vision)
  • Flashes of light in one or both eyes
  • Blurred vision
  • Gradual reduction in peripheral (side) vision
  • Curtain-like shadow over your visual field

How can I treat a damaged retina?

If you believe you are suffering from a retinal tear or detachment, it is important to seek immediate medical attention. Retinal damage that goes untreated may lead to permanent vision loss and blindness. Retinal tears and detachments can be repaired with procedures and surgeries such as:

  • Laser
    A laser makes small burns around the retinal tear. The resulting scar seals the retina to the underlying tissue, which helps prevent further damage, like retinal detachment.
  • Freezing treatment (cryotherapy)
    A special freezing probe applies intense cold and freezes the retina around the retinal tear. The resulting scar helps secure the retina to the eye wall.
  • Scleral buckle
    A flexible band (scleral buckle) around the eye acts as a counter weight to the force that’s pulling the retina out of place. This procedure is performed in an operating room.
  • Pneumatic retinopexy
    A gas bubble is injected into the vitreous space (gel-like substance in the center of the eye) in combination with laser surgery or cryotherapy. This bubble gently pushes the retinal detachment back into place at the back of the eye.
  • Vitrectomy
    Often used in conjunction with a scleral buckle procedure, vitrectomy replaces the vitreous gel with a gas bubble to keep the retina in place. Your body’s own fluids will gradually replace the gas bubble.

Austin Retina Associates has more than 40 years experience performing retinal surgery with excellent outcomes. Call 877-925-7649 to schedule an appointment.

What are the Symptoms of Retinal Detachment?

Last month, we shared the symptoms of retinal tears and how they can cause a sudden onset of black spots (floaters) in your field of vision, blurred vision and a gradual decrease in peripheral (side) vision. Retinal detachment has similar symptoms to retinal tears and may result in significant vision loss if left untreated.

A retinal detachment is a serious eye condition that occurs when the retina falls or slides off the back of the eye. When this happens, people start to see a dark area in their peripheral vision that gradually gets bigger and bigger. This is usually an urgent medical condition that requires treatment as soon as possible to avoid permanent vision loss.

What are common risk factors for retinal detachment?

There are certain factors that increase your risk for retinal detachment. Common risk factors for retinal detachment include:

  • Cataract surgery
  • Eye trauma
  • Lattice degeneration (thinning of the outside edges of the retina)
  • High myopia (severe nearsightedness)
  • Previous history of retinal tear
  • Previous history of retinal detachment in the other eye
  • Family history of retinal detachment

What are common symptoms of retinal detachment?

A detached retina isn’t usually painful, and can happen without warning. If you’re at risk for a detached retina, it’s important to know the warning signs. Common symptoms of retinal detachment include:

  • Photopsia (brief flashes of light that occur outside the central part of your vision)
  • Significant increase in the number of ‘floaters’ (small flecks or threads) in your field of vision
  • Darkening of your peripheral vision or a curtain
  • Straight lines start to appear curved

If you have any of the symptoms noted above, it’s important to seek immediate medical care for retinal detachment in Austin to avoid permanent vision loss. Call Austin Retina Associates at 877-925-7649 to schedule an appointment.

What are the Symptoms of Retinal Tears?

The retina is the inner lining of the eye; it is the part of the eye that contains light-sensitive tissue and creates vision. Retinal tears can happen as a result of trauma to the eye or a naturally occurring posterior vitreous detachment (PVD).

What is posterior vitreous detachment (PVD)?

The vitreous is a clear gel-like substance that is attached to the retina at birth. With age, PVD occurs when this gel naturally separates from the retina. In most cases, it does not cause any issues. For those with abnormally ‘sticky’ vitreous gel, however, PVD can spontaneously cause retinal tears.

“As commonly discussed with my patients, untreated retinal tears may result in retinal detachment and vision loss,” explains Dr. Agustin Martinez.

What are common symptoms of retinal tears?

Suffering from a retina tear is serious and often requires medical treatment to prevent vision loss. Common symptoms of retinal tears include:

  • Sudden onset of black spots or ‘floaters’ in your field of vision
  • Photopsia (flashes of light) in one or both eyes
  • Blurred vision
  • Gradually decreased peripheral (side) vision
  • A curtain-like shadow over your visual field

When should I see a doctor?

If you or a loved one is experiencing any of these symptoms, you are at an increased risk of developing retinal detachment. Retinal detachment can cause blindness and should be treated as a medical emergency. The skilled physicians at Austin Retina Associates urge you to seek immediate medical attention, particularly if you:

  • Are over the age of 50
  • Have a family or personal history of retinal detachment
  • Are extremely nearsighted

Common Causes of Macular Holes in Young Adults

A macular hole is a small break in the macula of the eye, which is the central part of the retina that gives people the ability to see details. When the macula is damaged, it can cause sudden blurred or distorted central vision. Central vision is needed for activities that require fine, sharp, straight-ahead vision, including reading, writing and driving.

When young adults experience a macular hole, not only can it limit their ability to see, but it can also limit their day-to-day activities. Macular holes can be treated, however, with a vitrectomy—a common treatment for this condition. During the surgery, a retinal specialist will remove the gel that is filling the injured area (macular hole) of the eye. This allows the eye to heal, help the hole close and restore central vision. The surgery lasts between 45 to 90 minutes and recovery is usually between four to eight weeks.

Causes of macular holes in young adults

These are the three most common causes of macular holes in young adults:

  • Injury or trauma
    Young adults who participate in high-contact activities are at an increased risk of developing a macular hole following blunt trauma to the eye. James Dooner notes that this is by far the most common cause of all macular holes in young people.
  • High myopia
    Young adults with high myopia—nearsightedness requiring a corrective lens prescription of at least -6.00 diopeters (D)—are at an increased risk of developing macular holes.
  • Ocular inflammation

Ocular inflammation is inflammation of the uvea, or middle layer of the eye, and is often caused by autoimmune disorders, inflammatory disorders or other diseases that weaken the immune system. Ocular inflammation may also result from a normal immune response of the body fighting an eye infection.

“The bottom line is that macular holes are very rare in young adults,” says Dr. Dooner. “They are much more common in the elderly.”
