Identifying the Gene Mutations that Cause Myopia

Researchers at Duke Medicine believe they have found the gene mutations that cause the common eye disorder myopia (nearsightedness). The Researchers have discovered that when the genes that regulate copper and oxygen in eye tissue mutate, they can result in high-grade myopia, a condition that has been linked to an increased risk for issues such as:

  • Glaucoma
  • Retinal detachment
  • Cataracts

These findings, however preliminary, are paving the way for future research into copper deficiency and its link to high-grade myopia. Researchers are hoping to find a link that will enable them to help prevent serious disorders by addressing copper deficiency rather than necessitating more invasive procedures.

Protecting Your Eyes

High-grade myopia effects only two percent of the population, but myopia itself is the most common eye disorder in the United States. While there is no cure for myopia, it can be treated with glasses, contact lenses, and often through surgical procedures such as LASIK and PRK.

If you suffer from myopia and are interested in learning more about your options, talk to your ophthalmologist to find the solution that is best suited to meet your particular needs.

Studying the Origins of Eye Disease

Researchers at Sweden’s Lund University are using new technology in hopes of determining why people suffer vision loss due to issues such as retinal detachment and glaucoma. Up to this point, research on eye diseases that lead to vision loss have focused almost entirely on the biomechanics of the eye. This new research, a collaboration between the Departments of Clinical Sciences and Biology at Lund University, will focus instead on the biomechanics of the entire central nervous system in hopes of finding an explanation as to why people develop these diseases.

Researchers have already grown retinal tissue from adult pigs that has been stretched to a similar state as a normal human eye. They have found that when the mechanical balance is disturbed, by being compressed for example, the tissue dies in a matter of days. Their initial findings indicate that the biomechanical factors that control tissue health in the central nervous system influence eye diseases that lead to vision loss. Their hope is to not only better understand these diseases, but to discover more effective late-term treatments and even a potential cure.

About Glaucoma

Glaucoma is a condition in which the optic nerve becomes damaged. There is currently cure for glaucoma, but it can be treated when caught early on. Symptoms of glaucoma include a sudden onset of vision disruption such as blurriness, but in many instances the disease is caught only through frequent eye examinations.

If you have not recently been screened for glaucoma, please find an ophthalmologist in your area to schedule an eye exam today.

Man Has Sight Restored after 55 Years of Blindness

New York – A 63-year-old man has vision in his right eye for the first time in more than 55 years. When he was 8 years old, he suffered a detached retina after his right eye was hit with a stone. He had experienced blindness in his right eye ever since.

Recently, the man went into the New York Eye and Ear Infirmary complaining of pain and redness in his eye. Doctors found swelling, bleeding, and a high fluid pressure in his right eye. After cleaning the eye and prescribing a drug to prevent the formation of new blood vessels, the eye was able to detect the source of a bright light for the first time since the man was a child.

As a result, doctors believed it was worth trying to re-attach his retina. However, they acknowledged that there was no guarantee the procedure would restore his vision. When a retina is detached for such a long period of time, it can result in permanent damage.

However, the surgery was successful, and the man is once again able to see out of his right eye. Doctors believe the surgery was successful because of the low “height” of the man’s detached retina. According to doctors involved in the procedure, this is the first time a man has had his sight restored after such a prolonged period of blindness.

According to Dr. Olusola Olawoye, “To the best of our knowledge, this is the first report of visual recovery in a patient with long-standing traumatic retinal detachment. This is not only a great result for our patient, but has implications for restoring eyesight in other patients, especially in the context of stem cell research into retinal progenitor cells which may be able to be transplanted into diseased retinas to restore vision.”
