Conjunctival grafting and cytotoxic drugs for advanced and recurrent pterygia

Although there are many surgical methods for treating pterygium, there are also several complications, the most important of which is recurrence, which usually associated with increased conjunctival inflammation, induced astigmatism and aggravated preoperative symptoms. Repeated surgery often worsens the situation, as loss of conjunctival tissue and scarring can result in obliteration of the fornices and mechanical restriction of ocular movement. In this retrospective study, forty two cases were operated for advanced primary and recurrent pterygium. In twenty six cases excision and free conjunctival auto graft taken from superio-temporal bulbar conjunctiva were done, in sixteen cases excision, application of mitomycin c and sliding flap graft were done. In one case [3.8%] there was graft failure, that occurred in the first post operative week, in three cases out of the grafted group [8.7%] recurrence of the Pterygia was reported within three months postoperative, recurrence occurred in one case [6.3%] in the sliding flap group
