Tissue tuck technique provides alternative method of pterygium removal

A pterygium consists of a triangular, thickened mass of conjunctival and subconjunctival fibrovascular tissue with elastotic degeneration that crosses the limbus and invades the cornea, possibly interfering with vision.
Global incidence of pterygium ranges from about 1% to 25% based on the population studied, with higher concentration in the tropical regions of the world. The association between ultraviolet light exposure and pterygium may to some extent explain the geographic variation in pterygium prevalence.
Visual compromise can be due to direct obstruction or secondary corneal distortions
