Internal Radiation Therapies : Pterygium
A pterygium is a thickening of conjunctiva onto the cornea on one or both sides of the eye. The growth can slowly progress until it seriously impacts vision. A pterygium can be removed by surgery, but it often grows back during the healing process. Using a brachytherapy form of radiation treatments to the affected region of the eye after surgery can prevent the membrane growths from recurring.
The procedure involves up to three treatments, all occurring within a two week span after your surgery. The radiation is delivered only to the surface of the eye and the dose to the lens of the eye is very low. The procedure is painless. After the procedure, you’ll wear an eye patch for about an hour to protect the eye from dust.
