To analyse the efficacy of different exsection range in pterygium excision combined with conjunctival limbal autograft transplantation.

The clinical data of 86 eyes of 86 patients with ptergium, from Jan. 2016 to Jan. 2017 were analyzed retrospectively.Among them 2 cases were recurrent pterygium. All cases were divided into 2 groups randomly.Group A, 44 cases, treated with pterygium extended excision combined with Tenon’s capsule excision.Group B, 42 cases, received obvious hyperplasia pterygium excision only.The follow-up time was 1 year.Postoperative recurrence rates, efficacy and complications between both groups were compared and analyzed.

The difference of length, width of pterygium invaded the cornea and the age of onset were not statistically significant between the two groups (P=0.247, 0.185, 0.125). In group A, the conjunctival of grafting bed occurred persistent congestion in 3 eyes after surgery. At the end of follow up, no recurrent or scar exposure occured.In group B, there were 10 cases with repeated conjunctival congestion in grafting bed. The conjunctival fibrovascular tissue proliferation and significant scar tissue exposure occured in 5 eyes(11.9%).

Pterygium extended excision combined with Tenon’s capsule excision is an efficient method for pterygium.It may reduce recurrence and improve postoperative conjunctival congestion.
