Pseudopterygium is sometimes referred to as cicatricial pterygium. A true pterygium has edges that can be elevated with forceps or under which a probe can be passed A true pterygium aries from a pinguecula. A pseudopterygium arises from destruction of the marginal, corneal epithelium through trauma, e.g. caustics, burns or inflammation.The adjacent conjunctiva migrates to the injured area and becomes fixed to it. A pseudopterygium does not show any tendency to progress. It is able to develop at any point of the corneal circumference.Reference: Thiel's Atlas der Augenkrankheiten, fig. 424, 6th edition.
