摘要

As the corneaCornea, the limbus and the surrounding conjunctivaConjunctiva are equally exposed to the environment and its irritations, especially to ultraviolet light, they are also vulnerable to the development of tissue atypia and dysplasia occasionally transforming into malignant tumors. A very common fibrovascular proliferation of the conjunctivaConjunctiva is the pterygium, which is mostly located in the nasal (more often than in the temporal) interpalpebral zone and is accompanied by irregular astigmatismAstigmatism, visual impairment, dryness and other surface issues. Even if a lot of risk factors for the pterygium are well known, its pathogenesis is still not yet completely understood. Therefore, it remains necessary to improve its understanding to decrease recurrence rate and to optimize its treatmentTreatment, especially the surgical therapyTherapy.
