Abstract

The cornea, the outermost tissue of the eye, harbors the most nerves of any tissue on the body’s surface. These nerves are vital to maintaining eye health and vision. However, corneal nerves are often damaged after corrective eye surgeries, such as LASIK. Inexplicably, corneal nerves regenerate poorly following LASIK resulting in reduced corneal sensitivity and dry eye. Here we determine whether thyroid hormone may represent a therapy to enhance corneal nerve regeneration by studying its stimulatory effects on corneal nerve growth. We have found that thyroxine (T4), the main hormone secreted by the thyroid gland, can significantly enhance the rate of nerve growth and increase corneal nerve density when applied ectopically to developing chick embryos. We are currently studying whether T3, the metabolite of T4 and more active form of thyroid hormone, displays similar or disparate effects to T4 when applied to chick embryos.
