An African Thunderstorm

Today we’ll take a departure from the typical eye care related topics.  If you have never heard of  Perpetuum Jazzile, they are an a cappella group from Slovenia.  Here is a video of them performing Africa, a popular hit of the 1980s, originally performed by the group Toto.  Check out the African thunderstorm sound effects at the beginning and the beat box percussionist, all without instruments …. amazing.  Turn your sound up.  It starts quietly.

Preventing Vision Problems in Children Must Become a Priority in The US

That is the opinion of The National Commission on Vision & Health, in a new report entitled “Building a Comprehensive Vision Care System“, found that 25% of school age children have undiagnosed vision problems and that correcting this must become a national health care priority.

91837233_f94352da20_mSome of the vision problems cited in the literature review included undiagnosed nearsightedness, farsightedness, amblyopia, retinoblastoma, congenital defects, and strabismus.  The report went on to state that a vision screening was not a substitute for an eye exam and that eye exams from an optometrist or ophthalmologist were a very effective way to detect vision problems in children.

In 2004 The Vision council of America estimated that the rate of undetected vision problems in children to be 25%.  The 2010 National Health Objective 28-4 to reduce blindness and visual impairment in children and adolescents has experienced little progress in it’s goal to reduce childhood blindness.

In 2002 the American Public Health Association (APHA) issued a statement supporting regular eye exams in children to improve the detection rate of vision problems instead of regular screenings.  APHA recommended eye exams at age 6 mos, 2 years and 4 years.  A failure of the current screening program is the lack of follow through for children when problems are detected.  “Most forms of vision loss in children are preventable.  Improving the access to eye care for children should be as important as are our current childhood vaccination programs” said Dr. Richard Driscoll.

Sixteen states do not require any vision assessment prior to a child entering school.  The remaining states require some for of vision assessment prior to a child entering school, however only five states require a follow up examination to the screening.  Screenings are clearly not effective if the results are not acted upon.  Only three states, Illinois, Kentucky and Missouri have legislated mandatory eye exams prior to a child entering school.

Cost was found to be an issue with getting visual assessments for children.  Uninsured children did not receive a well child visit 54% of the time.  Often a well child visit includes a visual assessment.

The recommendations of the study to improve access to eye care for children  included funding national campaigns to educate the public regarding the need to seek care for their child, setting up national standards to be adopted by all states, assure adequate vision coverage by all public and private insurers.

Gene Therapy Restores Vision

Gene Therapy SurgeryScientists at the University of Florida Restore Some Sight to Three Adult Patients with Congenital Vision Loss

One year ago the retina of two men and one woman in their 20s were injected with a harmless virus that contained vision correcting genes.  All three patients lived with severe vision loss from a congenital problem call Leber’s Congenital Amaurosis Type 2.  A gene responsible for a necessary protein used in the visual process is defective, gene therapy fixes the failed gene.  One year after the gene therapy treatment these patients reporting being able to see light which was a significant improvement in their vision.  One of the patients reported that she was able to see her parents clock, she had never been able to do this before.  The study has two more years to run and it is likely that more patients will be added.

This is a very exciting medical development and shows that gene therapy holds great promise.  There are so many genetic conditions, not only in the eye but the entire body, that can benefit from this type of treatment.  Much research still needs to be done, however this lays the groundwork for promising future development. The exciting thing about this discovery is that it shows that it is possible to fix bad genes and improve people’s lives.

Computer Glasses Help Reduce Eyestrain & Neck Pain

Computer glasses can not only help reduce eyestrain but they also reduce neck pain at your desk.  Numerous factors need to be addressed to maximize your comfort and effectiveness while working at the computer.  Computer related eyestrain is especially common for those approaching their 50s and above.

When working at our computer we often find ourselves raising our chin to make the monitor clear.  This puts our neck in a very bad, uncomfortable position.  Everyone that experiences neck pain should see their eye doctor about computer glasses. A few minutes to read a quick email is not a problem, however the longer you spend in this position the worse it is for your eyes, your posture and your neck.  Computer glasses place your monitor in the proper focus allowing you to look directly at the monitor while still allowing you to view reading material at a normal reading distance.

Another important consideration while working at the computer is your blinking.  When we work at the computer we become so engrossed in what we are doing that our blink rate goes down which increases the symptoms of dry eye syndrome.  The video below gives a good summary of computer vision syndrome and computer glasses.

How to Insert, Remove and Take Care of Soft Contact Lenses

Coopervision has produced this 10+ minute video on how to insert, remove and take care of soft contact lenses.    There is a brief commercial at the beginning outlining the different kinds of contact lenses offered by CooperVision.  This video outlines the right way to do it.  Throw away that contact lens solution everyday!

Retinal Melanoma Diagnosed with the Optomap Retinal Exam

Here is a video where a retinal melanoma was initially diagnosed using the optomap® Retinal Exam.  The optomap® is a new generation of scanning laser ophthalmoscope that takes a series of 16 photos in 1/4 of a second and puts them together making a panoramic view of the back of a patient’s eye.  The optomap® allows us to view over 80% of the back of the eye without dilating the pupils.  The optomap® was also recently featured on the TV Show The Doctors.

The first 6 seconds of the video below is blank.

How are Custom Soft Contact Lenses Made

Here is an interesting video from the TV show How It’s Made on how custom soft contact lenses are made.  The vast majority of soft contact lenses  prescribed today are mass produced and molded, however if you have a lot of astigmatism or wear special custom ordered contact lenses then the odds are good it was manufactured in a similar manner.

What Kind of Eyeglass Lenses are Recommended for Children?

Assessing the visual needs of your child with an eye exam is the first step in protecting your child’s vision.  It is equally important to select lenses that will not only make them see well but also protect their eyes.

Polycarbonate or Trivex lenses are the only lens types that have the potential to reduce—not increase—the risk of serious eye injury.   Polycarbonate and Lexan are used in bullet-proof windshields, safety glasses, helicopter canopies and many other hi performance applications.   Other lens types, including glass and regular plastic (CR-39)  will break into pieces upon impact.  Often the impact from an object does less damage to the victim than the broken eyeglass lenses.

Both polycarbonate and Trivex are thin, lightweight and highly impact resistant.   Kids can do crazy things and accidents can happen, therefore polycarbonate and Trivex are not just recommended for sports but should be used to protect their eyes everyday.

Trivex is highly scratch resistant making it the best option for children.  Polycarbonate is much softer and therefore less scratch resistant, however it is slightly less expensive.  Both lens materials naturally block 100% of UV light without any additional coatings.  The optical qualities of Trivex are much better than those of polycarbonate, therefore there is less distortion and reflection from an ophthalmic lens made of Trivex.  Both lens materials are available in Transitions (get darker outside, lighter inside) and accept an antireflective coating, which prevents reflections, making the lenses look transparent.
