The patient is most likely suffering from a pterygium. Living near the equator is associated with pterygium development. Pterygium are benign growths of the conjunctiva associated with excessive exposure to wind, sunlight, or sand. Other risk factors include working outdoors with high exposure to UV rays. Symptoms of pterygium include persistent irritation, redness, foreign body sensation, and tearing. If the pterygium advances over the cornea it can impair vision. Peate discusses work related eye injuries including corneal abrasions, burns, and globe injury. The review states that eye patching does not reduce discomfort following corneal abrasions. Working with chisels, hammers, grinding wheels, or saws places patients at risk for globe injuries. The treatment of chemical eye burns is immediate irrigation with copious amounts of fluid. Janson et al. review the surgical management of pterygium. Pterygium are noncancerous proliferations of conjunctiva. Treatment is most often surgical and may be required because of discomfort, cosmesis, or obstruction of vision. Following surgical excision, pterygia can often recur. Figure A displays a ptergium which is characterized by elastotic degeneration of collagen and fibrovascular proliferation. Incorrect Answers: Answers 1,2,4,5: These are not risk factors for pterygium formation.
