To introduce a new technique which aids to remove the pterygium head and facilitates the establishment of a smooth and clear corneal surface without extra scraping or polishing.
We used 12 eyes of 12 patients undergoing pterygium excision. Air was injected into the side of the cap of the pterygium head with a 30-gauge needle, to create a dissection plane between the pterygium head and the cornea. After blunt dissection and excision of the pterygium, the conjunctival autograft technique was applied. Complications, postoperative smoothness and clarity of the cornea, and the recurrence rates were evaluated.
Dissection with air was successfully performed in 9 eyes (75%) in which blunt dissection was carried out easily. The corneas were clear and smooth postoperatively. In 3 eyes (25%) dissection with air was not completely successful, and scraping with a crescent blade had to be performed. One of the eyes with incomplete air dissection could not be clearly scraped. No major complications were observed. The recurrence rate was 8.3% (1 eye).
This new technique is a safe, easy and cheap method for removing the pterygium head from the corneal surface, which also facilitates the establishment of a clear and smooth corneal surface.
[Show abstract][Hide abstract] ABSTRACT: SUMMARY To evaluate and compare the effectiveness and safety of the human amniotic membrane graft with intraoperative application of Mitomycin C in primary pterygium surgery. In 60 consecutive patients, 60 eyes were included in the study. The patients were randomly divided into two groups, primary pterygium excision with intraoperative Mitomycin C (0.2 mg/ml) were applied to the 30 patients and amniotic membrane grafts were applied to the other 30 patients. Recurrence was detected in two patients (%6.66) who received amniotic membrane grafts, and in five patients (%16.66) who received primary pterygium excision with intraoperative Mitomycin C. No statistical difference was observed between groups according to the reccurence (p > 0.05). Suture lysis in early postoperative period was detected in one patient (%3.33) who received amniotic membrane grafts. Scleral melting was developed in one patient (%3.33) and punctate epitheliopathy was developed in one patient (%3.33) who received primary pterygium excision with intraoperative Mitomycin C. No statistical difference was observed between groups according to the complications (p > 0.05). Although no statistical difference was observed between two groups according to complication and reccurence, amniotic membrane graft method was safer than primary pterygium excision with intraoperative Mitomycin C.
