PurposeTo evaluate the efficacy of conjunctival autograft
transplantation with amniotic membrane transplantation in primary pterygium surgery
To compare postoperative recurrence rates between conjunctival autograft transplantation only and conjunctival autograft transplantation with amniotic membrane transplantation in primary pterygium surgery.
Patients and methodsPatients with pterygium who underwent conjunctival
autograft transplantationFrom January, 2001 to May, 2009 in Department of
ophthalmology, Ajou university medical center
Single surgeon
Retrospective study, chart review
Patients and methods
2 groups (66 eyes of 63 patients)Group 1: conjunctival autograft transplantation only
23 eyes of 22 patients
Group 2: conjunctival autograft transplantation with amniotic membrane transplantation 43 eyes of 40 patients
Patients and methods Removal of pterygium from cornea with Beaver blade.
Patients and methods Tenon and subconjunctival fibrovascular tissue were undermined
and excised extensively with a pair of spring scissors.
Patients and methods Marked the donor conjunctiva with Gentian violet made to
measure the size of conjunctival defect.
Patients and methodsConjunctival graft was attached to the conjunctival edges and
episclera with interrupted 10–0 Nylon sutures
Patients and methodsAmniotic membrane was cut a proper-sized graft, which would
cover the conjunctival transplantation area and corneal epithelial defect area. The membrane was placed over the epithelial side on top. Pinch together the membrane and conjunctiva, interrupted suture was done with 10-0 Nylon.
ResultsM:F = 9:13 (group 1)
17:23 (group 2)
Average follow up period
group 1 : 11.7 ± 24.2 month
group 2 : 12.4 ± 16.8 month
Average recurrence interval
group 1 : 3.2 (1 – 4)month
group 2 : 5 (4- 6)month
ResultsRecurrence of pterygium was observed in 5 of 23 eyes that
received conjunctival autograft transplantation only. (21.7%)
Recurrence of pterygium was observed in 2 of 43 eyes that
received conjunctival autograft transplantation and amniotic
membrane transplantation.(4.6%)
Therer is a statistically significant difference between two groups.
(p<0.05)
No major complications such as necrotizing scleritis, sclera ulcer,
corneal perforation were noted in either group after surgery.
Conclusion
This study showed that receiving both conjunctival autograft transplantation and amniotic membrane transplantation in pterygium surgery has a lower recurrence rate than conjunctival autograft transplantation only.
Therer is no major complications such as necrotizing scleritis, sclera ulcer, corneal perforation were noted after surgery.
