Abstract

PURPOSE
To compare postoperative recurrence rates between conjunctival autograft transplantation alone and conjunctival autograft transplantation with amniotic membrane transplantation in primary pterygium surgery.
METHODS
The authors conducted a retrospective analysis of 66 eyes from 62 patients who underwent primary pterygium surgery from January 2001 to May 2009. Twenty three eyes underwent conjunctival autograft transplantation alone, 43 eyes underwent conjunctival autograft transplantation with amniotic membrane transplantation.
RESULTS
Recurrence of pterygium was observed in 5 of 23 eyes that received conjunctival autograft transplantation alone. There were 2 cases of recurrence of 43 eyes that received conjunctival autograft transplantation and amniotic membrane transplantation. No major complications such as necrotizing scleritis, sclera ulcer, or corneal perforation were observed in either group after surgery.
CONCLUSIONS
The present study showed that receiving both conjunctival autograft transplantation and amniotic membrane transplantation in pterygium surgery has a lower recurrence rate than conjunctival autograft transplantation alone.

(B) Tenon's capsule and subconjunctival fibrovascular tissue are undermined and excised extensively with a pair of spring scissors. (C) Marked the donor conjunctiva with gentian violet made to measure the size of the conjunctival defect. (D) Conjunctival graft is attached to the conjunctival edges and episclera with interrupted 10-0 nylon sutures.

  Figure 2. Surgical technique of amniotic membrane transplantation. Amniotic membrane is cut a proper-sized graft, which will cover the conjunctival transplantation area and corneal epithelial defect area. The membrane is placed over the epithelial side on top. Pinch together the membrane and conjunctiva, interrupted suture is done with 10-0 nylon.
