Nashville, TN (PRWEB) July 31, 2014
Dr. Stewart Shofner of Shofner Vision Center in Nashville, TN was one of the first surgeons in the United States to successfully treat glaucoma by performing eye surgery using the iStent, the smallest medical device ever approved by the FDA. Dr. Shofner is also one of the first surgeons to recognize the benefits of using a procedure known as Selective Laser Trabeculoplasty (SLT) to successfully treat patients with glaucoma. Dr. Shofner and his colleagues now recognize that this procedure is a primary treatment for many patients who find it difficult and expensive to administer eye drops routinely.
Glaucoma is a condition where the eye’s natural drainage system becomes clogged and pressure builds up dangerously in the eye. It is a complicated disease in which damage to the optic nerve leads to progressive, irreversible vision loss. According to the World Health Organization, glaucoma is the second leading cause of blindness. Prevent Blindness America reported it is estimated that over 2.2 million Americans have glaucoma but only half of those know they have it. "A comprehensive eye exam and detecting glaucoma early is key in preventing permanent vision loss," say Dr. Shofner.
Glaucoma Treatment Options
Different treatment options may be considered depending on the type of glaucoma. Topical eye medications (eye drops) or oral medications (pills) can be very effective at controlling intraocular pressure to prevent eye damage for many patients. However, some patients may require surgery to reduce their intraocular pressure to a safe level by improving the outflow or drainage of fluids. After surgery, a patient’s dependency on expensive eye drops to control glaucoma is either reduced significantly or even eliminated. Others may need to continue using eye drops post glaucoma surgery.
The SLT Procedure
The selective laser trabeculoplasty (SLT) procedure increases outflow of internal eye fluid. The laser, performed by an ophthalmologist, is used to create tiny holes in the filtration angle of the eye, where the cornea and iris meet. The SLT creates minimal heat damage to adjacent tissue, which generally means the procedure can be repeated safely. Recent studies indicate and Dr. Shofner agrees that this laser procedure may be equally as effective as glaucoma eye drops for lowering internal eye pressure.
Shunts and Stents
Other options for glaucoma treatments include shunts and stents, which are small devices that are surgically inserted into the eye during a trabeculectomy to increase outflow of intraocular fluid and reduce high eye pressure. The iStent Trabecular Micro-Bypass (iStent) is made of surgical-grade titanium and is safely implanted in the internal eye area to re-establish a normal flow of fluids within the eye. Stents used in the medical industry are tubes inserted into the human body to improve blood flow or provide easy access for medications or even surgery. The iStent creates a new opening, which eliminates any blockage that hinders the eye’s natural fluid outflow. As with the SLT procedure, the iStent may be a permanent way to reduce or even eliminate a glaucoma patient’s reliance on medication.
Glaucoma treatments (laser and non-laser) are designed to decrease the production of intraocular fluid or increase the outflow (drainage) of this same fluid. Treatment is necessary to reduce or stabilize one’s intraocular pressure in order to prevent optic nerve damage.
Routine eye exams to determine early diagnosis are the best way to prevent vision loss from glaucoma. People that are high risk for developing glaucoma due to elevated intraocular pressure, family history, ethnic background, age or optic nerve appearance should consult with a qualified eye doctor or ophthalmologist to determine the frequency of their eye exams.
