Back Surgery and Vision Loss

About Vision Loss from Back Surgery
What does having back surgery have to do with vision loss? According to neurosurgeons who perform spine surgery, one of the risks of spine surgery is post operative vision loss (POVL). When operating on the spine, a rare but potentially devastating complication of lumbar spine surgery is indeed POVL, of three types that seems to be increasing in frequency. These include one type called ischemic optic neuropathy (ION) which occurs due to restricted blood flow to the optic nerve, another is called central retinal artery occlusion (CRAO) which is due to a blockage in the main artery that supplies the retina with oxygen and nutrients and third is called cortical blindness (CB) most likely due to some blockage in the visual cortex of the brain that is responsible for “seeing.” These complications are quite rare but the risks can occur when there are very long operation times, in patients who have a difficult time being positioned on the operating table and especially in those that are obese. Neurosurgeons take many preoperative and intraoperative precautions to avoid these complications which, except for an unusual event, are successful in avoiding vision loss.

However, if you or someone you know is having or has had back or spine surgery, please be aware that any change in your vision should immediately be reported to your neurosurgeon and you eye doctor so as to prevent vision loss.

Slowing Nearsighted Progression

About Nearsighted or Myopic Progression
Myopia is a common disorder, affecting approximately one-third of the U.S. population. High myopia is associated with an increased risk of sight-threatening problems, such as retinal detachment, choroidal degeneration, cataracts, and glaucoma. Slowing the progression of myopia could potentially benefit millions of children in the U.S. To date, few clinical approaches for myopia control and slowing myopic progression have proven to be consistently effective. Treatment options such as undercorrection of myopia, gas permeable contact lenses, and bifocal or multifocal spectacles have all been proven to be ineffective for myopia control, although one recent clinical trial using executive top bifocal spectacles on children with progressive myopia has shown to decrease the progression to nearly half of the control subjects. The most effective methods are the use of orthokeratology contact lenses, soft bifocal contact lenses, and certain eye drops not specifically approved for this use. We encourage parents children experiencing rapid myopic progression to discuss which if any of these options might be helpful or appropriate for their children.

Retinitis Pigmentosa Help

About Retinitis Pigmentosa
Retinitis pigmentosa (RP) is a progressive inherited disease of the eye, in which the light-sensitive photoreceptor cells located in the retina degenerate. This results first in the loss of night and peripheral vision, eventually progressing to the loss of central vision and total blindness. It is the leading cause of inherited blindness in the developed world.

The disease, which affects approximately 1.5 million people in the world, has no cure, but thanks to research done at the University of California-Santa Barbara, a new stem cell therapy may soon be available that protects photoreceptor cells from the damaging effects of the gene mutation. So far, only a small number of legally blind patients with RP have begun a trial. The trial is the first attempt to use stem cells to prevent the loss of vision from RP. An experimental injection of retinal stem cells is placed in the eye with the hope that the growth factors from these cells will protect the retinal cells and prevent them from dying, thus preserving the patient’s remaining vision.

If you, a family member or someone you know would like to learn more about Retinitis Pigmentosa or many new stem therapies being developed for diseases of the retina, please call Doctor & Associates-203-227-4113, visit Doctor & Associates in Fairfield County, Google+ or facebook.com/doctorandassociates to schedule an appointment.
