These weird spots and jagged lines are scaring me!

Have you ever seen a temporary black spot in your vision? How about jagged white lines? Something that looks like heat waves shimmering in your peripheral vision?

If you have, you may have been experiencing what is known as an ocular migraine. Ocular migraines occur when blood vessels spasm in the visual center of the brain (the occipital lobe) or the retina.

They can take on several different symptoms but typically last from a few minutes to an hour. They can take on either positive or negative visual symptoms, meaning they can produce what looks like a black blocked-out area in your vision (negative symptom), or they can produce visual symptoms that you see but know aren’t really there, like heat waves or jagged white lines that look almost like lightning streaks (positive symptoms).

Some people do get a headache after the visual symptoms but most do not. They get the visual symptoms, which resolve on their own in under an hour, and then generally just feel slightly out of sorts after the episode but don’t […]

Why Polarized Glasses Are Essential in Winter

Not everyone understands the importance of sunglasses when the weather turns cold.

Polarized sunglasses are usually associated with Summer, but in some ways it is even more important to wear protective glasses during the Winter.

It’s getting to be that time of year when the sun sits at a much different angle, and its rays impact our eyes and skin at a lower position. This translates to an increase in the exposure of harmful UV rays, especially if we are not wearing the proper sunglasses as protection.

Polarized sunglasses, which are much different than the older dye-tinted lenses, are both anti-reflective and UV resistant. A good-quality polarized sunglass lens will protect you from the entire UV spectrum. This not only preserves your vision, but it also protects the skin around the eyes, which is thought to have a much higher rate of susceptibility to skin cancer.

Snow poses another issue that can be countered by polarized sunglasses.

Snow on the ground tends to act as a mirror because of its white reflective surface and this reflection […]

Tips for Making Those New Glasses Last

Now that you have picked up your new pair of prescription eyeglasses, your focus should become taking care of them. This is a task many disregard, but it is imperative that you make sure you are following a couple simple steps to keep the quality of your vision with your new spectacles.

We are all guilty of using a garment when in a rush to wipe away a pesky smudge on our glasses. This act is unfortunately the worst thing you can do for your lenses.

No matter how clean your clothes are, dust particles and even small bits of sand and debris cling to them. Since eyeglass lenses are not made of diamonds, these tiny little particles can do tremendous amounts of damage to your new lenses. The smallest little crumb can grind a scratch directly in your line of vision, which in turn can render your glasses almost useless.

Most of us know what it feels like trying to concentrate on the world in front of you when there is a little scratch distorting […]

4 Good Reasons for Older Adults to Have Regular Eye Exams

The American Optometric Association has recommendations for how often adults need to get their eyes examined and those recommendations vary according to the level of risk you have for eye disease.

Patient age (years) Asymptomatic/low risk At-risk
19 through 40 At least every two years At least annually, or as recommended
65 and older Annually At least annually or as recommended

 

As you can see, the guidelines recommend more frequent exams as you get older. Here are the TOP 4 REASONS why you need your eyes examined more frequently as you get older:

 

1. Glaucoma

Glaucoma is the second leading cause of blindness in the United States. It has no noticeable symptoms when it begins and the only way to detect glaucoma is through a thorough eye exam. Glaucoma gets more and more common as you get older. Your risk of glaucoma is less then 1% if you are under 50 and over 10% if you are 80 or over. The rates […]

Diabetic Retinopathy Must-Knows for Everyone with Diabetes

Diabetic retinopathy is an eye condition that can affect the retina of people who have diabetes.

The retina is the light-sensitive tissue that lines the back of the eye, and it detects light that is then processed as an image by the brain. Chronically high blood sugar or large fluctuations in blood sugar can damage the blood vessels in the retina. This can result in bleeding in the retina or leakage of fluid.

Diabetic retinopathy can be divided into non-proliferative or proliferative diabetic retinopathy.

Non-proliferative diabetic retinopathy:  In the early stage of the disease, there is weakening of the blood vessels in the retina that causes out-pouching called microaneurysms. These microaneurysms can leak fluid into the retina. There can also be yellow deposits called hard exudates present in the retina from leaky vessels.

Diabetic macula edema is when the fluid leaks into the region of the retina called the macula. The macula is important for sharp, central vision needed for reading and driving. The accumulation of fluid in the macula causes blurry vision.

Proliferative diabetic retinopathy: […]

Know the 3 F’s of Retinal Detachments

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 […]

Don’t Play Trick or Treat with Your Eyes

Fall brings a lot of fun, with Halloween bringing loads of it.

But did you know that some Halloween practices could harm your vision? Take Halloween contacts, for instance. They vary widely, with everything from monster eyes to goblin eyes to cat eyes to sci-fi or  glamour looks. They can be just the added touch you need for that perfect costume. However, some people do not realize that the FDA classifies contact lenses as medical devices that can alter cells of the eye and that damage can occur if they are not fit properly.

Infection, redness, corneal ulcers, hypoxia (lack of oxygen to the eye) and permanent blindness can occur if the proper fit is not ensured. The ICE, FTC, and FDA are concerned about costume contacts from the illegal black market because they are often unsafe and unsanitary. Proper safety regulations are strictly adhered to by conventional contact lens companies to ensure that the contact lenses are sterile and packaged properly and accurately.

Health concerns arise whenever unregulated black-market contacts come into the US market […]

7 Tips from an Eye Doctor on Getting the Most from Your Exam

The eye holds a unique place in medicine. Your eye doctor can see almost every part of your eye from an exterior view. Other than your skin, almost every other part of your body cannot be fully examined without either entering the body (with a scope) or scanning your body with an imaging device (such as a CAT scan, MRI, or ultrasound).

This gives your eye doctor the ability to find many eye problems just by looking in your eye. Even though that makes diagnosing most problems more straightforward than in other medical specialties, there are still many things you can do to get the most out of your eye exams. Here are the top 7 things you can do to get as much as possible out of your exam.

1) Bring your corrective eyewear with you. Have glasses? Bring them. Have separate pairs for distance and reading? Bring them both. Have contacts? Bring them with you and not just the lenses themselves but the lenses prescription, which is on the box they came in. What […]

Contact Lens Care 101

Oftentimes, contact lens wearers will skimp on their lens care because some of the solutions are costly and it seems like a good way to save some hard-earned cash. But this is not a good idea.

Cutting corners can result in infections or irritations, and after one or two copays to your eye doctor's office you probably will have spent more than what you saved in a year by cutting corners–plus you have to deal with your discomfort and inability to wear your contact lenses while you are being treated.

The reasons you clean your contacts is to give increased lens comfort, prolong lens oxygen permeability, and to protect your eyes from infection. The reason you have to disinfect your contact lenses is – as nasty as it may sound – that your eyeball and eyelids are covered in essential bacteria that are kept in check by your body’s immune system. When you remove your contact lens at night it is covered in these essential bacteria. If you don't kill them overnight this will allow the […]

Dropless Cataract Surgery Is Now Available

After cataract surgery, there are two main issues we try to control: preventing infection and controlling inflammation.  Traditionally, we prescribed antibiotic eye drops to prevent infection, as well as steroid eye drops to control post-operative inflammation. But eye drops can be hard for some patients to put into their eyes. Now we have some alternatives to using drops after surgery.   

There are some antibiotic solutions we can place inside the eye at the end of the cataract surgery that have been shown in most studies to do as good or better a job preventing infection as using antibiotic eye drops before and after surgery.

The FDA approved two new steroid delivery methods to reduce post-operative inflammation that have the potential to eliminate post-op steroid eye drops in most (but not all) patients who are undergoing cataract surgery. Those two products are called Dexycu and Dextenza.

Dexycu is a white bolus of steroid medication that is injected inside the eye after cataract surgery. It will not be visible in most patients because it is injected behind […]
