Pterygiums can cause irritation, redness, inflammation and tearing. They can also create a foreign body sensation -- the feeling that something is in the eye. Eye drops or ointments can reduce irritation, but in some cases, surgery is necessary. According to USA Today's Health Encyclopedia, there are three reasons surgery would be the prescribed treatment. First, if the pterygium grows over the cornea, it can cause vision problems. Second, a pterygium may be unsightly and embarrassing for some patients. Third, it can cause excessive discomfort.
TREATMENTS: The traditional surgery to remove pterygiums was "very quick and simple," Dr. Hovanesian said. The abnormal growth was removed from the eye; however, "The problem with this is that very often they would grow back usually within a few months and sometimes even larger than they started." There was a 55 percent chance of the pterygium returning. About 15 years ago, surgeons began covering the bare area where the growth was removed with tissue from the eye. Now, doctors replace the area with amniotic membrane from the human placenta, which reduces inflammation and scarring. In addition, the surgery requires no stitches. "When we use these materials, whether it's human tissue for a transplant or amniotic membrane, we hold them in place using, instead of stitches, a type of glue, which is actually made from human blood." The 'glue' is thoroughly tested for safety and forms an almost instant bond with the graft, holding it in place. It is more comfortable for the patients because they don't feel stitches. It also cuts the surgery time almost in half. Pterygiums also grow back less than one percent of the time with the No-Stitch surgery
PREVENTION: Wearing sunglasses helps reduce exposure to UV rays, dust and wind, which can help protect your eyes from developing pterygiums. The wraparound styles are most effective. Wearing a hat can also shield the eyes from environmental damage. Artificial tears are also useful in decreasing irritation by keeping the eyes moist and dust-free.
