Summary: | Background: Pterygium is a common degenerative eye disease. Despite various surgical methods to treat
pterygium, recurrence is the main complication. The main issue is finding a surgical method with the lowest
recurrence.
Objective: to compare the complications, recurrence rate and the cosmetic effects of two surgical techniques,
namely conjunctival rotation autograft (CRA) and conjunctival autograft (CA), in treating pterygium.
Methods: This randomized clinical trial was conducted at Khalili Hospital in Shiraz, Iran, from January to
August 2015. Forty-five eyes from 45 patients were studied. The patients were randomly divided into two groups
using the blocking method. The patients of one group were operated on by the CRA technique, while the other
group was operated on by the CA method. The patients were checked for the recurrence of pterygium, and other
complications at the end of the first, third, and sixth month. Finally, the data were analyzed using SPSS version
21. Results: The mean age of the patients was 42.5 years. The recurrence of pterygium was not observed in any of
the patients 6 months after the surgery. Following 6 months after the operation, graft retraction occurred during
the first week for one patient (4.5%) in the CA group, and five patients (21.7%) in the CRA group. The
prevalence rate of graft injection among the patients of the CA and CRA groups 6 months after the operation was
9.1% and 65.2%, respectively. There was a significant correlation between injection intensity and the
dissatisfaction of the patients with the operation’s outcome (p=0.017).
Conclusion: CRA with mitomycin is considered as an effective method to reduce the recurrence of pterygium
after operation. This technique can be used as an acceptable method for pterygium operation, especially for
patients with insufficient conjunctiva.
Clinical trial registration: The trial was registered at the Iranian Registry of Clinical Trials (http://www.irct.ir)
with the Irct ID: IRCT2016092119581N2. Funding: The study was financially supported by Shiraz University of Medical Sciences (SUMS) (grants No.
8901). |
