Do you worry about losing your vision ?



80 percent of Americans worry about losing their vision yet 86 percent of those who already have an eye disease do not get routine exams.

     A well known filmmaker, Joe Lovett was scared, really scared. Being able to see was critical to his work as a documentary filmmaker and, he thought, to his ability to live independently. But longstanding glaucoma threatened to rob him of this most important sense — the sense that more than 80 percent of Americans worry most about losing, according to a recent survey.

    Partly to assuage his fears, partly to learn how to cope if he becomes blind, and partly to alert Americans to the importance of regular eye care, Mr. Lovett, 65, decided to do what he does best. He produced a documentary called “Going Blind,” with the telling subtitle “Coming Out of the Dark About Vision Loss.”

    In addition to Mr. Lovett, the film features six people whose vision was destroyed or severely impaired by disease or injury:

Jessica Jones, an artist who lost her sight to diabetic retinopathy at age 32, but now teaches art to blind and disabled children. Emmet Teran, a schoolboy whose vision is limited by albinism, a condition he inherited from his father, and who uses comedy to help him cope with bullies.Peter D’Elia, an architect in his 80s who has continued working despite vision lost to age-related macular degeneration. Ray Korman, blinded at age 40 by an incurable eye disease called retinitis pigmentosa, whose life was turned around by a guide dog and who now promotes this aid to others. Patricia Williams, a fiercely independent woman legally blind because of glaucoma and a traumatic injury, who continues to work as a program support assistant for the Veterans Administration. Steve Baskis, a soldier blinded at age 22 by a roadside bomb in Iraq, who now lives independently and offers encouragement to others injured at war.

     Sadly, the nationwide survey (conducted Sept. 8 through 12 by Harris Interactive) showed that only a small minority of those most at risk get the yearly eye exams that could detect a vision problem and prevent, delay or even reverse its progression. Fully 86 percent of those who already have an eye disease do not get routine exams, the telephone survey of 1,004 adults revealed.

   The survey was commissioned by Lighthouse International, the world-renowned nonprofit organization in New York that seeks to prevent vision loss and treats those affected. In an interview, Lighthouse’s president, Mark G. Ackermann, emphasized that our rapidly aging population predicts a rising prevalence of sight-robbing diseases like age-related macular degeneration and diabetic retinopathy that will leave “some 61 million Americans at high risk of serious vision loss.”

                                                           The Benefits of a Checkup

   Low vision and blindness are costly problems in more ways than you might think. In addition to the occupational and social consequences of vision loss, there are serious medical costs, not the least of them from injuries due to falls. Poor vision accounts for 18 percent of broken hips.

  So, why don’t more of us get regular eye exams? For one thing, they may not be are covered by Medicare and many health insurers unless there is a eye disease found. But even those who have insurance or can pay out of pocket are often reluctant to go for regular eye exams. Fear and depression are common impediments for those at risk of vision loss, said Dr. Bruce Rosenthal, low-vision specialist at Lighthouse. Patients worry that they could become totally blind and unable to work, read or drive a car, he said.

  Yet many people fail to realize that early detection can result in vision-preserving therapy. Those at risk include people with diabetes, high blood pressure, high cholesterol or cardiovascular disease, as well as anyone who has been a smoker or has a family history of an eye disorder like macular degeneration, diabetic retinopathy or glaucoma.

   Smoking raises the risk of macular degeneration two to six times, Dr. Facchiano indicated. The eyes are truly a window to the body, and a proper eye exam can often alert physicians to a serious underlying disease like diabetes, multiple sclerosis or even a brain tumor.

                                                              Reasons Not to Wait

     Dr Facchiano OD FAAO along with the AOA recommends that all children have “a basic professional eye exam” before they start elementary school. “Being able to read the eye chart, which tests distance vision, is not enough, since most learning occurs close up,” he said. Studies indicate that “One in three  schoolchildren has a vision deficit. Learning and behavior problems can result if a child does not receive adequate vision correction.”

     Annual checkups are best done from age 20 on, and certainly by age 40, Dr. Facchiano OD FAAO said. Waiting until you have symptoms is hardly ideal. For example, glaucoma in its early stages is a silent thief of sight. It could take 10 years to cause a noticeable problem, by which time the changes are irreversible.

     For those who already have serious vision loss, the range of visual aids now available is extraordinary — and increasing almost daily. There are large-picture closed-circuit televisions, devices like the Kindle that can read books aloud, computers and readers that scan documents and read them out loud, Braille and large-print music, as well as the more familiar long canes and guide dogs.

     On Oct. 13, President Obama signed legislation requiring that every new technological advance be made accessible to people who are blind, visually impaired or deaf.

     Producing “Going Blind” helped to reassure Mr. Lovett that he will be able to cope, whatever the future holds. Meanwhile, the regular checkups and treatments he has received have slowed progression of his glaucoma, allowing him to continue his professional work and ride his bicycle along the many new bike paths in New York City.

  Dr Facchiano recommends that you start the new year out by scheduling an eye exam.

What Eye Exams Detect

Most people think of eye exams as something done to detect a need for eye glasses, prescription sun glasses or contact lenses. That is one of the results of an eye exam, but that isn't what they are "for." The reason for eye exams is to check the total health of the eye. Sometimes, problems with seeing things clearly might be from eye diseases or other health issues that affect vision. Optometrists are trained at looking for health problems and will be able to detect a variety of diseases from the instruments used during an eye exam.

Here are the most common diseases caught by optometrists who practice full scope primary eye care:

Glaucoma

Macular Degeneration

Cataracts

Diabetes

High Blood Pressure

Cancer

When the doctors do a full examination, they'll be able to use all the tools available to them to make determinations if there are any underlying issues with reported vision problems. Sometimes, there won't be any reported vision problems and the diseases will be caught in an early stage that makes managing them much easier. So don't think that the only thing eye exams detect is a need for corrective lenses, they do so much more than that.

5 Things to Consider Before LASIK

Laser-Assisted In Situ Keratomileusis, or LASIK for short, is the medical procedure that changes the shape of the eye so that corrective lenses aren't needed as much, or at all. Many people ask me during the pre-screening for eye exams  if they are good candidates for the operation. When I hear that, I encourage a patient to talk with our optometrists and find out if LASIK is right for them. There are a lot of factors to consider that need to be weighed and balanced before going forward with the LASIK surgery.

There are people and groups who don't need LASIK

If someone has a slight prescription, or is really young, LASIK really isn't recommended or needed in a lot of cases. Take a look at your lifestyle, age and dependence on contacts or glasses and deeply consider if it will improve your day-to-day life or if would be just "nice" to have. There are risks with undergoing LASIK and certain people might lose more than they gain.

Are there problems with the eye beyond "not seeing well?"

If you have Glaucoma, past eye traumas, eye conditions like dry eyes or a host of other problems or complications related to the eye, there are complications that could result in diminished vision or vision loss. Always go in for an eye exam and make sure that everything checks out. It is now a requirement that vision remains stable for an entire year before proceeding with LASIK.

Researching and finding the best surgeon

Is the doctor experienced with the best knowledge and latest FDA approved equipment? That is the question everyone should ask, however, many people only consider price when shopping around for LASIK, but that should only be one of the many considerations when selecting a doctor to preform the operation. Doing a little legwork and getting all the facts on LASIK centers in imperative before getting the procedure done. Your primary eye care doctor will also be able to make recommendations.

Commitment

LASIK isn't just a one time surgery that makes the need for glasses or contacts disappear. There many steps along the road to the operation and many steps that follow. People who get the LASIK done might even need to go back for touch-ups a few years down the road.

Won't solve all problems

A lot of times, people will still have to wear reading glasses after a LASIK operation. People looking to be totally free of glasses or contacts need to be aware that there still might be need for corrective lenses following the operation for things like close-up vision.

--

If you want to know more information about LASIK, the FDA has a great website that covers all the bases about what to expect, what to do/not do and other bits of information that is useful for people considering the surgery.

The Difference Between an Optometrist and...



There are a lot of "O" words when it comes to eye care. There are optometrists, ophthalmologists and opticians. Most people confuse the terminology as the "Three O's" have one major thing in common, they all care about the eyes.

Optometrists are the first line of defense for primary eye care. They adminsiter eye exams, prescribe glasses, treat some eye diseases, diagnose diseases like Cataracts and Glaucoma, fit contact lenses and preform a few other services related to eye health and vision. You can tell if a doctor is an Optometrist if their title is "OD." Our Optometrists in Madison and our Optometrists in Rockford are "ODs."

If there are serious finding during an eye exam, an Optometrists will refer a patient out. Ophthalmologists typically specialize in a portion of the eye and will preform surgery when it necessary. Many Ophthalmologists have the title "MD" but some carry the title "DO." A lot of times Optometrists and Ophthalmologists will co-manage patients together.

Opticians are the remaining piece of the puzzle. They are the people that fit patients with glasses. They take face measurements, make lenses, inform people about lens choices and help people pick out frames. They fill the prescription given by an eye doctor.

To simplify the definitions-

Optometrist = primary eye care doctors

Ophthalmologists = eye specialists

Opticians = fill the prescriptions given by a doctor

Eye Care 101: Inserting Contact Lenses

Eye Care is one of the most important parts in the practice of Optometry. Good eye care practices are both the responsibility of patients and doctors. This series of posts will cover the basics that highlight important topics in Optometry to show how eye care is important.

So many people wear contact lenses that they are just as common as glasses wearers. Every contact lens wearer is also trained in specific ways to make sure that they keep their contacts clean and eyes healthy when they insert them each morning. As wearers get more comfortable with inserting and removing the contacts, some bad habits can form. And it all starts with inserting contact lenses. In terms of eye care, it is paramount to keep up a good regimen so contacts won't expose the eye to disease and infection. The following is the proper steps to follow when handling contact lenses to insert them. The biggest key to keeping eyes healthy with contact lenses is making sure everything is clean




  • First, make sure to wash your hands throughly. A mild anti-bacterial soap is the best kind to use.

  • Be sure to check for any debris or particles in the solution or on the lens.

  • Double check to the lens to see if it is inside out. A good way to tell is look at the contact at eye level. If there is a slight "bell" shape to the contact, it needs to be flipped inside out.

  • Avoid over handling contacts. They are made from delicate materials and can pick up germs, particles or other thing you don't want touching your eye ball.

  • Once the contact is on the eye, look down and close your eyes for a few seconds to let the contact settle.


This information is generally given out during an eye exam, but it is always good to call an Optometrist if you have any questions. Here is a video with some more information about contacts from the solution brand Opti-Free. That is the brand our eye doctors use and recommend.

Eye Care 101: 20/20 Vision

Eye Care is one of the most important parts in the practice of Optometry. Good eye care practices are both the responsibility of patients and doctors. This series of posts will cover the basics that highlight important topics in Optometry to show how eye care is important.

One thing most people know about optometry is that 20/20 vision is good to have. It means that at a distance of 20 feet, objects are seen clearly and crisply. If an Optometrist were to say you had 20/100 vision, that would mean that you would have to stand 20 feet away from an object while someone with normal vision could stand 100 feet to see the object just as clearly.



I tend to find pictures help explain this. In the above image, the man has 20/100 vision. He has to stand 20 feet away from the vase on the table while the woman can stand 100 feet away and see the same clarity as the man. The 20/(number) figure that is given by Optometrists part of what is known as "visual acuity."

The reason why everyone doesn't have 20/20 vision is due to a variety of reasons including nearsightedness (blurry distance vision), farsightedness (blurry close-up vision), astigmatism (non-spherical eye) or eye disease. Optometrists will be able to determine the causes during a comprehensive eye exam. The way to check distance vision is generally done by reading lines off those famous eye charts. Because of there are many factors for differences in visual acuity, that could mean that even people with 20/20 vision will note their vision could use adjustment.


The most common way to correct distance vision by prescribing glasses or contacts. There are also visual therapy programs and medications that can help improve vision, when the situation calls for them. Since the eyes are rapidly changing all the time, annual eye exams are important to make sure that visual corrections are current and aiding the health of the eye.

20/20 vision is a good barometer for healthy vision as it tests distance and clarity; however, it is only one part in the story. Saying someone has "perfect" sight when they have 20/20 vision is entirely misleading. What is missing are the other indicators of optimal vision like peripheral (side) vision, coordination of the eyes, depth perception, ability to focus and color testing. In summary, 20/20 vision is important but it isn't the end all, be all measurement for healthy vision.
