It is more common for the pterygium to be present on the nasal conjunctiva and then to extend onto the surface of cornea, although it can present temporally, as well as in other locations. [nhp.gov.in]

A pterygium presents as an elevated, superficial, external ocular mass on the perilimbal conjunctiva that grows into and onto the cornea. Pterygia can vary in size, height, and rate of growth. [decisionmakerplus.net]

  Results: Thirty-eight subjects (20.4%) were outdoor workers and 148 (79.6%) were indoor workers. Outdoor workers were more likely to be male smokers and alcohol drinkers with lower family income and higher sunlight exposure than indoor workers. [link.springer.com]

The most widely recognized etiologic factor is ultraviolet radiation, which leads to degeneration of the conjunctiva. However, pterygium was recently found to have several tumor-like characteristics. [nature.com]

Cumulative genetic damage from chronic UV exposure was speculated to be a shared etiology between pterygia and preneoplastic diseases [ 10 ]. The current standard of care is wide local excision, followed by cryotherapy to the margins. [research-journal.net]
