Outstanding Information About Myopia

My friend and colleague Dr. Nathan Bonilla-Warford has put an outstanding piece on his blog.  Instead of reinventing the wheel, I’ve pasted his post below and here’s a link to it directly in his blog.

From Dr BW’s blog…….

My colleagues and I think and talk about myopia (nearsightedness) every day. We talk about the drawbacks (and rewards) of being myopic. We talk about the causes and treatment options for myopia, both short and long term.

But I have never seen a day like today, with myopia in all the papers and on every major TV news program. Given how quickly news travels today, the total number of people thinking and re-thinking about their eyes and vision is probably higher today than it has ever been!

Yesterday morning, I received an email about a newly released study, “Increased Prevalence of Myopia in the United States Between 1971-1972 and 1999-2004.” While I take it as common knowledge that nearsightedness is increasing in much of the world, including the United States, even I was stunned to see this headline about the study: “Myopia Prevalence Rose 66% over 30-Year Period” There is no way around it, a 66% increase is a lot!

So I posted the link on Twitter and Facebook, but I didn’t really have the time to dedicate to the study until today. And then the really big news hit. There are stories on myopia on  NPRDiscover,  the LA Times, and video segments on Good Morning America and local affiliates such as these and these.

So since this is such a hot topic today, I’ll share what I tell patients almost every day at the office.  But first let me say this:  while vision science has advanced tremendously, and we have a better understanding than ever, there still is a lot that we do not know about the details of nearsightedness and its development. And, although this may shock you to read, there are some less-than-ethical people who will claim to have all the answers and will say with a straight face that they have THE ONLY WAY to either prevent or eliminate nearsightedness or glasses. The truth is that we don’t know exactly how this works and we can never make promises because what may work for 1000 people may not work for you.

But we can say some things about myopia more generally. There is a genetic component for sure, but just because you and your spouse are nearsighted is not a guarantee that your children will be . In fact, there may be more commonly a genetic susceptibility than an actual myopia “gene.” And clearly there are other factors involved because while the population is changing (due to aging and immigration) our US genes haven’t changed that much in 30 years, but our eyes have!

So, as many of the links above point out, our lifestyle can have an impact on vision. Our eyes are inherently best-suited for looking off into the distance. This is easy and natural. Yet today we spend an increasing amount of time and effort focusing within arms-length and in some cases just a few inches. And while we have always had (and will continue to have, I hope) kids and adults with their noses buried in bound books, the truth is that intensely playing tiny video games or texting does require more visual effort. And I can attest from seeing patients at Bright Eyes that children are engaged in these activities at younger and younger ages.

So – if a patient has increasing nearsightedness, or seems predisposed to be nearsighted what are the options? Here  are the refractive options from least to most aggressive.

  • Do nothing. Some people prefer to not take any action because they do not have need to see better at a distance and they prefer the vision up close. This is totally reasonable, as long as it is an educated choice and not just by default or neglect. However, this is not itself a treatment for myopia and in fact may promote myopia in the long run.
  • Traditional glasses or contacts. This will help a patient see clearly in the distance which is necessary for things like driving or going to school which are important. But it will not address any underlying problems leading to increasing myopia.
  • Bifocal Glasses. This method was more popular in prior decades to slow down myopia progression. The scientific studies have not shown it to be as helpful generally, but may be for a  subset of people with specific visual problems.
  • Multifocal soft contact. There is small but growing evidence that multifical contacts, like Proclear EP, can provide clear distance vision and limit the progression of nearsightedness.
  • Orthokeratology (Corneal Reshaping). There is several scientific studies that have shown that this can provide safe, clear daytime vision, and slow or stop progression of myopia. You can read more about this here. And I have written more about this here.
  • Atropine drops. This method of myopia control involved the use ofprescription eye drops to keep the eyes dilated. This has been used for years and is more popular in Asia, but has not caught on in the US, due to side effects.

But regardless of which method is employed above, it is wise to take frequent, brief breaks from near work. Looking up and away every 15 minutes or so is a good idea, because there is some evidence that it is not the total time during near work, but the length of the individual periods of work that make a bigger difference. Getting outside more is a good idea, but it is not clear if it is the distance vision, sunlight, or some other benefit. Of course, this is true not just for your eyes, but for your body and mind, too!

As vision professionals, we clearly have much work to do in understanding more about why and how myopia occurs. But it is exciting to know that there are treatment options that can reduce the likelihood of progression.

If you have concerns about your vision or if your children have not been thoroughly evaluated, call us at 813-792-0637 to schedule an appointment. After reviewing the examination findings, we can discuss concerns and treatment options that may be right for you.

Be well!

Whew! It Missed Us….

The major storm that is.  We did get some snow, but not that “white death” that was predicted.   There are times when Lake Michigan is a real savior!  I’m sure that we’ll get our share of snow and more ice this year, but it was nice to dodge the first big one this winter!


Avocational Pursuits

After listening to my 11 year old son play his 6 string electric guitar, I finally took the plunge and have started playing 4 string electric bass.  What a great outlet, I’m not any good at all yet, but I’ve gotten to the point that I’ll jam away in the basement and really enjoy myself.

One of the best things that I did was buy a decent bass.  I picked up (actually an early Christmas present from my lovely wife Carmen) a Peavey BXP NTB at Schmitt music here in Racine.  Its a gorgeous piece of workmanship with its natural wood finish finish and I love the narrow (referred to as “fast” by us guitar players <G>) neck.

I’m only a bit more than a month into my guitar career, and I don’t think that I’ll be giving up the eye doctor gig any time soon, but it sure is fun!


An Innovator In Education

One of my favorite instructors at IU Optometry, Paul Pietsch passed away this week.  He was way ahead of his time.  Back in the 1980’s he was recording tutorials on histology and ocular neuroanatomy.  His students used these recorded lessons to observe histological sections under light microscope.   Despite being a pretty dry topic, he was always slipping in small anecdotes and comments which brought a smile to your face as you peered into the microscope.

Flash forward about 20 years and you see podcasts being offered by dozens or more universities via iTunes as well as recorded media courses on school websites.

Dr. Pietsch, you will be missed, and you certainly were a trailblazer.  I’ll think of you and your pipe the next time I listen to a podcast!
