Limbal versus conjunctival autograft transplantation for advanced and recurrent pterygium1
Section snippets
Materials and methods
Between January 1995 and April 1997, 86 eyes of 86 consecutive patients meeting eligibility criteria were enrolled in this study. All patients were younger than 40 years (range, 27–39 years) and were followed up for a minimum of 36 months (range, 36–63 months). Criteria for eligibility were: a pterygium extending at least 3 mm beyond the limbus, no other ocular surface pathologic features or infection, and no collagen vascular disease.
Complete ocular examination was carried out and
Results
Seven patients were excluded because their follow-up was less than 1 year because they left the country. Results of 79 patients with advanced primary or recurrent pterygia were included in this study. Of them, 76 were males (96%) and 3 were females (4%), with a mean age of 33 years (range, 27–39 years). The mean follow-up period was 49 months (range, 36–63 months). Patients’ data are shown in Table 1. No statistically significant differences existed between the two groups in preoperative
Discussion
In our prospective, randomized study, we found limbal-cunjunctival autograft transplantation more effective than conjunctival autograft alone in prevention of recurrence after pterygium excision. Although no recurrence was seen in the limbal-conjunctival autograft group, both techniques were effective in cases of advanced primary pterygia, with no statistically significant difference (P = 0.208). In case of recurrent pterygia, limbal-conjunctival autograft was more effective in preventing
