Pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation on recurrent pterygium

Abstract:

AIM:To discuss the effective method of decreasing the postoperative recurrence rate of recurrent pterygium.

METHODS:Totally 126 cases(126 eyes)with recurrent pterygium were randomly divided into A group(56 cases)and B group(70 cases). Group A was treated by pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation, group B was treated by amniotic membrane transplantation. The followed-up time after surgery was 6-24mo.

RESULTS:In group A, postoperative 5-7d(average 5.62±1.38d), cornea epithelium was repaired. In group B, postoperative 7-10d(average 7.38±1.12d), the corneal wound was healed. There was statistical significant difference between two groups(t=4.307,P<0.05). Three cases recurrence were noted in A therapeutic group(56 cases), the recurrent rate was 5.4%; Twelve cases recurrence were noted in B compared group(70 cases), the recurrent rate was 17.1%. There was statistical significant difference between two groups(P<0.05).

CONCLUSION:It is suggested that pterygium conjunctive reverse transplantation combined with amniotic membrane transplantation is effective in the treatment of recurrent pterygium.
