Signs of Retinal Detachment — the 3 F’s

If you are seeing the 3 F's, you might have a retinal tear or detachment and you should have an eye exam quickly.

The 3 F's are:

  • Flashes – flashing lights.
  • Floaters – dozens of dark spots that persist in the center of your vision.
  • Field cut – a curtain or shadow that usually starts in peripheral vision that may move to involve the center of vision.

The retina is the nerve tissue that lines the inside back wall of the eye and if there is a break in the retina, fluid can track underneath the retina and separate it from the eye wall. Depending on the location and degree of retinal detachment, there can be very serious vision loss.

If you have a new onset of any of the three symptoms above, you need to get in for an appointment fairly quickly (very quickly if there are two or more symptoms).

If you have just new flashes or new floaters you should be seen in the next few days. If you have both new flashes and new floaters or […]

Why Daily Contacts Are So Popular

When soft contact lenses first came on the scene, the ocular community went wild.

People no longer had to put up with the initial discomfort of hard lenses, and a more frequent replacement schedule surely meant better overall health for the eye, right?

In many cases this was so. The first soft lenses were made of a material called HEMA, a plastic-like polymer that made the lenses very soft and comfortable. The downside to this material was that it didn’t allow very much oxygen to the cornea (significantly less than the hard lenses), which bred a different line of health risks to the eye.

As contact lens companies tried to deal with these new issues, they started to create frequent-replacement lenses made from SiHy, or silicone hydrogel. The oxygen transmission problem was solved, but an interesting new phenomenon occurred.

Because these were supposed to be the “healthiest” lenses ever created, many people started to overwear their lenses, which led to inflamed, red, itchy eyes; corneal ulcers; and hypoxia (lack of oxygen) from sleeping in lenses at night. A new solution […]

Catch These Vision Conditions Early

What do amblyopia, strabismus, and convergence insufficiency all have in common? These are all serious and relatively common eye conditions that children can have.

Did you know that 80% of learning comes through vision? The proverb that states ”A picture is worth a thousand words” is true!  If a child has a hard time seeing, it stand to reason that she will have a hard time learning.

Let’s explore amblyopia, or “lazy eye.” It affects 3-5% of the population, enough that the federal government funded children’s yearly eye exams through the Accountable Care Act or ObamaCare health initiative. Amblyopia occurs when the anatomical structure of the eye is normal but the “brain-eye connection” is malfunctioning. In other words, it is like plugging your computer into the outlet but the power cord is faulty.

Amblyopia needs to be caught early in life–in fact if it is not caught and treated early (before age 8) it can lead to permanent vision impairment. Correction with glasses or contacts and patching the good eye are ways it is treated. Most eye doctors agree […]

Healthy Life, Healthy Eyes

Living an overall healthy life is good for your eyes. Healthy vision starts with healthy eating and exercise habits.

There's more to complete eye health than just carrots. Are you eating food that promotes the best vision possible? Learn what foods boost your eye well-being and help protect against diseases. Here are important nutrients to look for when selecting your foods.

  • Beta carotene or Vitamin A (helps the retina function smoothly): carrots and apricots
  • Vitamin C (reduce risk of macular degeneration and cataracts): citrus and blueberries
  • Vitamin E (hinders progression of cataracts and AMD): almonds and sunflower seeds
  • Riboflavin (helps your eyes adapt in changes in light): broccoli and bell peppers
  • Lutein (antioxidant to maintain health while aging): spinach and avacado
  • Zinc (transfers vitamin A to the retina for eye-protective melanin productions and helps with night vision): beans and soy beans
  • DHA (helps prevent Dry Eye): Fatty fish like salmon and tuna

Keep in mind, cooked food devalues the precious live enzymes, so some of these foods are best eaten raw.

 

This blog provides general information and discussion about eye health and related subjects. The words […]

Ummm…Why are you wearing those?

What’s up with people wearing those big sunglasses after cataract surgery?

The main reason is for protection – physical protection to assure nothing hits the eye immediately after surgery, and protection from sunlight and other bright lights.

We want to protect the eye from getting hit physically because there is a small incision in the eyeball through which the surgeon has removed the cataract and inserted a new clear lens. In most modern cataract surgeries that incision is very small – about one-tenth of an inch in most cases. The vast majority of surgeons do not stitch the incision closed at the end of surgery. The incision is made with a bevel or flap so that the internal eye pressure pushes the incision closed.

The incision does have some risk of opening, especially if you were to provide direct pressure on the eyeball. Therefore, immediately after surgery we want you to be careful and make sure that you or any outside force doesn’t put direct pressure on the eye. The sunglasses help make sure that doesn’t happen while you […]

This Might Just Be the Most Important Test Your Child Will Take

Is making an appointment for a comprehensive eye exam for your children on your back-to-school checklist? It needs to be.

No amount of new clothes, backpacks, or supplies will allow your child to reach their potential in school if they have an undetected vision problem. 

The difference between eye exams and vision screenings

An annual exam done by an eye doctor is more focused than a visual screening done at school. School screenings are simply "pass-fail tests" that are often limited to measuring a child’s sight clarity and visual acuity up to a distance of 20 feet. But this can provide a false sense of security.

There are important differences between a screening and a comprehensive eye exam.

Where a screening tests only for visual acuity, comprehensive exams will test for acuity, chronic diseases, color vision, and eye tracking. This means a child may pass a vision screening at school because they are able to see the board, but they may not be […]

Charles Bonnet Syndrome and Visual Hallucinations

Have you ever heard of Charles Bonnet?  He was a Swiss naturalist, philosopher, and biologist (1720-1793) who first described the hallucinatory experiences of his 89-year-old grandfather, who was nearly blind in both eyes from cataracts.  Charles Bonnet Syndrome is now the term used to describe simple or complex hallucinations in people who have impaired vision.  

Symptoms

People who experience these hallucinations know they aren't real.  These hallucinations are only visual, and they don't involve any other senses. These images can be simple patterns or more complex, like faces or cartoons.  They are more common in people who have retinal conditions that impair their vision, like macular degeneration, but they can occur with any condition that damages the visual pathway.  The prevalence of Charles Bonnet Syndrome among adults 65 years and older with significant vision loss is reported to be between 10% and 40%.  This condition is probably under reported because people may be worried about being labeled as having a psychiatric condition. 

Causes

The causes of these hallucinations are controversial, but the most supported theory is deafferentation, […]

An Eye on Fireworks Safety

Fireworks Eye Injuries Have Skyrocketed in Recent Years

Fireworks sales are exploding across the country through the Fourth of July. As retailers are blazing their promotions, we and the AAO are shining a light on this explosive fact–the number of eye injuries caused by fireworks has rocketed in recent years.

Fireworks injuries cause approximately 15,600 emergency room visits each year, according to data from the U.S. Consumer Product Safety Commission. The injuries largely occurred in the weeks before and after the Fourth of July. The CPSC’s fireworks report showed that about 2,340 eye injuries related to fireworks were treated in U.S. emergency rooms in 2020, up from 600 reported in 2011.

To help prevent these injuries, the Academy has addressed four important things about consumer fireworks risks:

  1. Small doesn’t equal safe. A common culprit of injuries are the fireworks often handed to small children – the classic sparkler. Many people mistakenly believe sparklers are harmless due to their size and the fact they don’t explode. However, they can reach temperatures of up to 2,000 degrees […]

Your Makeup Could Be Drying Out Your Eyes

Dry Eye Disease affects more than 5 million people in the United States, with 3.3 million being women and most of those being age 50 or over. And as people live longer, dry eye will continue to be a growing problem.

Although treatment options for dry eyes have improved recently, one of the most effective treatments is avoidance of dry eye triggers.

For some that might mean protecting your eyes from environmental triggers. To do that experts recommend using a humidifier in your home, especially if you have forced hot-air heat; wearing sunglasses when outside to help protect your eyes from the sun and wind that may make your tears evaporate faster; or being sure to direct any fans  – such as the air vents in your car – from blowing directly on your face. For others, it may mean avoiding medications that can cause dry eyes.

There is one other trigger that may need to be avoided that doesn’t get as much notice: the potentially harmful ingredients in cosmetics.

Cosmetics do not need to prove that they are “safe […]

Frame Your Face

Choosing a new pair of eyeglasses can be a daunting task.

Making a decision on what style glasses you will be wearing for the next year until your vision is checked again can be stressful. This is one of the many reasons opticians are here for you. In many ways, this may be the most important task for the optician, because keeping you happy with the way you look motivates you to wear your glasses daily.

Most people’s reaction is to play it safe with new glasses and stick with something relatively similar to what they are currently wearing.

While not necessarily a bad decision, this isn’t something opticians try to promote. Opticians often spend time meeting with frame representatives and browsing the Internet to keep up with the ever-changing trends in the world of eyeglass frames. And it’s a great feeling to successfully “update” your image with a new set of frames. Many patients are amazed at the difference a well-fit and -styled pair of glasses makes on their overall look.

There are many simple tips […]
