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.
ABSTRACT
Pterygium is a common surgical ocular disease which recurs frequently. Various different techniques have been developed for the successful surgical treatment of pterygium and among them, autograft transplantation is known as the best successful surgical method. For the prevention of recurrence, the corneal epithelium must heal before the fibrovascular tissue grows and reaches to limbus. For this, we have believed that limbal transplanta- tion is more suitable than conjunctival transplantation. We had performed limbal-conjunctival autograft trasplata- tion for 52 patients with primary pterygia whose age was under 40 years old,or whose pterygia had involved above 5mm beyond limbus and had shown diffuse subconjunctival fibrovascular tissue. The recurrence rate was 1.9%and therewere no complications and no surgical problems. Therefore,we recommend this surgical technique as a safe and effective method of treating primary pterygia with the risk factors of recurrence.

The recurrence is common problem to treat pterygium. Many surgical procedures were adopted to reduce the recurrence rate. We evaluated the surgical results of limbal conjunctival autograft transplantation (LCAT) accompanying application of 0.02% mitomycin C intraoperatively in 10 patients (10 eyes) who had a recurrent pterygium. There were 7 eyes with first recurrence and 3eyes with second recurrence. Mean age of the patients was 57.4 years, and mean follow-up period was 9.3 months. After a pterygium was excised, a sponge soaked in a solution of mitomycin C 0.02% was applied to the sclera at the site of the surgical bed for 2 minutes, then superior temporal limbal tissue was taken with conjunctival flap and transplanted to the excised area. None of all cases recurred for follow-up period and donor conjunctival site was well reepithelialized. In concluion, LCAT accompanying application of 0.02% mitomycin C intraoperatively was effective and safe method for recurrent pterygium.
