May is Healthy Vision Month

May is Healthy Vision Month

What does that mean for you? It means that now is the time to schedule a comprehensive eye  exam. 

While these are one of the exams we may often let fall by the wayside, they are extremely important to maintain our eye health. Comprehensive eye exams serve several purposes. During these exams, pupils, the circular black area in the center of the eye where light enters, are widened with eye drops or viewed without dilation through a special camera. This allows your Eye Doctor to check for vision problems and eye diseases, verify what stage of diseases your eyes may be in, and helps determine if you need glasses, contacts or other treatments. 

Comprehensive eye exams are crucial for all ages, here’s why: 

Pediatric exams test for visual acuity, lazy eye, color vision, ocular health, and more. These are extremely important to test for the school years ahead. 

For older children and teenagers, myopia (nearsightedness) is one of the biggest concerns that comprehensive eye exams detect. Myopia affects the eye’s ability to see distant images clearly. It is important to identify and treat early with glasses or contacts as children and teens begin to learn in larger spaces, play sports, and drive. 

Adult exams are recommended at least every two years, or as recommended by your eye care specialist. Exams for adults are necessary to catch eye conditions that can cause vision loss and even lead to blindness. Some of these conditions are cataracts, diabetic retinopathy, glaucoma, and age-related macular degeneration. 

There are several other conditions that comprehensive eye exams can expose that may not be found without a visit to your optometrist. 

Outside of eye exams, here are 5 ways you can help protect your vision: 

  1. Healthy eating. You know this! Healthy eating helps every part of your body. For your eyes, make sure to add dark, leafy greens and seafood that is high in omega-3 fatty acids to your plate. A great excuse to treat yourself to sushi! We’re adding a spicy sake maki roll to our cart… for delivery.
  2. Protective eyewear. Whether you’re chopping wood for the bonfire pit, mowing the lawn, painting your bedroom walls, or riding your motorcycle around town, protective eyewear is key. Blue-light protection glasses should also be considered to protect your eyes from all the time spent in front of computer screens.
  3. Sunglasses. Much like protective eyewear, sunglasses help protect your eyes from ultraviolet radiation delivered by sun. Not all sunglasses provide the same level of protection. Let us help you pick the best pair!
  4. Clean hands. Wash your hands before putting your contacts in and before taking your contacts out, simply to avoid infection.
  5. Stop smoking. Smoking is known to cause several diseases, but it can also lead to vision loss. It can increase the risk of age-related macular degeneration, cataracts, and more. Mark your calendar for your comprehensive eye exam and mark it as the day to stop smoking.

Punctal plugs are something we use to help treat Dry Eye Syndrome.  

This syndrome is a multifactorial problem that comes from a generalized decrease in the amount and quality of the tears you make.  There is often both a lack of tear volume and inflammation in the tear glands, which interfere with tear production and also cause the quality of the tears to not be as good.

We make tears through two different mechanisms.  One is called a basal secretion of tears, meaning a constant low flow or production of tears to keep the eye moist and comfortable.  There is a second mechanism called reflexive tear production, which is a sudden flood of tears caused by the excitation of nerves on the eye surface when they detect inflammatory conditions or foreign body sensations. It is a useful reflexive nerve loop that helps wash out any foreign body or toxic substance you might get in the eye by flooding the eye with tears.  Consider what happens when you get suntan lotion in your eye.  The nerves detect the irritation that the lotion creates, and your eyes quickly flood with tears.

That reflex mechanism is how some people get tearing even though the underlying cause of that tearing is dry eye.  They don’t produce enough of the basal tears, the eye surface gets irritated and then the reflex tearing kicks in and floods their eyes, tearing them up.  Once that reflex is gone then the eye dries out again and the whole cycle starts over.

One of the treatments for dry eyes is to put a small plug into the tear drainage duct so that whatever tears you are making stay on the eye surface longer instead of draining away from the eye into to the tear drainage duct and emptying into your nose.

There are several different types of punctal plugs.  Some are made of a material that is designed to dissolve over time.  Some materials dissolve over two weeks, while others can last as long as 6 months.  There are also plugs made out of a soft silicone material that are designed to stay in forever.  They can, however, be removed fairly easily if desired or they can fall out on their own, especially if you have a habit of rubbing near the inside corner of your eye.

One of the big advantages of punctal plugs is that they can improve symptoms fairly rapidly - sometimes as quickly as a day.

The long-term medical treatment for dry eyes such as Restasis, Xiidra or the vitamin supplement HydroEye can take weeks or months to have a good effect.

On the other hand, plugs simply make you retain your tears for a longer time; they don’t help the underlying inflammation.  That is where the medical treatment comes in.  Sometimes it is useful to use a temporary plug for more instant relief while you are waiting for the medical treatment to work.  Sometimes there is clearly just a deficiency of tears and not much inflammation and the plugs alone will improve your symptoms.

All in all, punctal plugs are a safe, effective and relatively easily-inserted treatment for dry eyes.
