There are many ways of treating the Pterygium from conjunctiva auto-gratfing to amniotic membrane with sutures or glue, to irradiation. As it is a small growth, Pterygiums do not usually require surgery unless it grows to where it covers the pupil, obstructing vision, or presents acute symptoms. However some of the irritating symptoms can be treated with artifical tears. There is no reliable medical treatment to reduce or even prevent the Pterygium progression. The only way to be sure to the Pterygium is completely removed is by surgerical removal. Long term follow up is required because Pterygiums may reoccur even after the surgery has been done.
