ABSTRACT
Background: Pterygium is a triangular wing shaped fiovascular growth of subconjunctival tissue on to the cornea. Surgical removal is the treatment of choice but no single technique is successful due to high recurrence rate. Aim: To evaluate the success and complications of sutureless glue–free conjunctival–limbal autografting in management of primary pterygium. Materials and Methods: A prospective interventional study was carried out in 60 patients to analyse the outcome of sutureless and glue–free conjunctival–limbal autograft for the management of primary nasal pterygium. The patients were followed up after 1 week, 3 weeks, 6 weeks and at 3 months postoperatively. The mean age of the patients was 38.28± 13.77 years (range 21–67), 55% of which were females. Graft retraction occurred in 3(5%) eyes. Haemorrhage was seen in 20(33.33%) eyes at 24 hours, which persisted in only 8(13.33%) eyes at 3 weeks and resolved completely in 100% of eyes at 6 weeks. Oedema was noted in 5(8.33%) eyes at 24 hours, and resolved completely by 1 week. Recurrence of pterygium was observed in 2(3.33%) eyes at three months of follow–up. Conclusion: Sutureless and glue–free conjunctival–limbal autograft following pterygium excision is an easy, quick, safe, effective, and economical option for the management of primary pterygium.
ABSTRACT
Objective: The objective of the following study is to compare the conjunctival graft thickness measured with anterior segment optical coherence tomography (OCT) after primary and recurrent pterygium excision. Design: Prospective, interventional and comparative study. Participants: A total of 20 eyes of 20 patients with primary pterygium (primary group) and 20 eyes of 20 patients with recurrent pterygium (recurrent group) were enrolled. Materials and Methods: All patients underwent pterygium excision with conjunctival autograft transplantation. Conjunctival graft thickness was measured at 1 week, 1 month and 3 months after surgery using the Visante‑OCT (Carl‑Zeiss Meditec, Dublin, CA, USA). Main outcome measure was the mean conjunctival thickness determined as the mean of three measurements at 1, 2 and 3 mm posterior to the scleral spur. Results: There were no statistically significant differences in age, sex, or laterality between the groups. Mean thickness of the graft in primary and recurrent groups, respectively, was 430 ± 127 μm and 461 ± 178 μm at 1 week after surgery (P = 0.587), 114 ± 19 μm and 162 ± 48 μm at 1 month after surgery (P = 0.001) and 109 ± 15 μm and 107 ± 18 μm at 3 months after surgery (P = 0.726). Conclusion: The findings revealed that conjunctival thickness after primary or recurrent pterygium excision was greatest at 1 week after surgery and continued to decrease for up to 3 months. Mean graft thickness differed significantly between the two groups only at 1 month after surgery.

ABSTRACT
·AIM: To investigate the efficiency of limbal conjunctival autografting technique in patients with primary pterygium.·METHODS: Fifteen eyes of 15 patients with primary pterygium underwent surgery for the removal of pterygium with limbal conjunctival autograft. After the pterygium excision, the limbal portion of the graft was oriented and sutured to the limbus at the recipient bed with the epithelial surface upside. Recurrence was defined as fibrovascular tissue of more than 1 mm over the cornea in the area of previous pterygium excision.·RESULTS: With mean follow-up period of 8 months, neither recurrences nor serious complications were recorded among our patients.·CONCLUSION; Simple excision followed by limbal-conjunctival autograft transplantation is a safe and very effective way of treating primary pterygium.
