Abstract

Introduction: Pterygium, one of the degenerative and prevalent ophthalmic
diseases, is more prevalent in equatorial and tropical areas. This study was
conducted in order to compare recurrence rate and surgical complications of
pterygium treatment with four different transplantation methods of conjunctival
autograft, conjunctival flap, using mitomycin-C with conjunctival autograft and
using mitomycin-C with bare sclera.
Methods: In this experimental study, pterygium treatment on 80 eyes from 68
patients was investigated. The transplantation methods were randomly allocated
to the patients and all operations were implemented by one surgeon. Pterygium
size of all patients was >2 mm. 21 eyes were treated with conjunctival autograft
method, 18 eyes with conjunctival flap method, 18 eyes with mitomycin-C with
conjunctival autograft method and 23 eyes were treated with mitomycin-C with
bare sclera method. Follow-up duration of the patients was between 6 to 24
months. The results were analyzed using t-test, Chi-Square and Analysis of
variance statistical tests.
Results: Recurrence rate for autograft transplantation method was 4.67%, for
conjunctival flap method was 16.67%, for conjunctival autograft with mitomycin-C
was 5.55% and of bare sclera with mitomycin-C was 8.70%. All recurrences
occurred within 2 months from operation and there was no surgical complication.
The relationship between recurrent pterygium and recurrence rates were
statistically significant (P<0.05).
Conclusion: Pterygium treatment with conjunctival autograft transplantation
method is simple and safe with minimum recurrence rate. Using mitomycin-C
with conjunctival autograft method has not any effect on recurrence rate and
surgical complications for suitable and selected patients.
