Using a biologic adhesive during pterygium surgery appears to yield a low recurrence rate and a short operation time, according to a prospective study by a researcher in Sweden.

"Further studies regarding the effect of sex, age and race in pterygium recurrence are needed," Marcelo Ayala, MD, PhD, said in the July issue of Cornea.

Working at Örebro University Hospital, Dr. Ayala evaluated the recurrence rate and operation time after performing pterygium surgery using a conjunctival autograft fixed with Tisseel Duo Quick (Baxter) on 88 patients with primary pterygium. In addition,

Dr. Ayala evaluated the influence of age, sex and country of origin of the patients on the recurrence rate.

Patients averaged 60.3 years of age at baseline; 67 of the patients were men and 21 patients were women. Sixty patients were of Swedish origin and 22 were considered non-Swedish.

Operation time averaged 11.8 minutes.

After 1 year of follow-up, the recurrence rate was 4.54%; patients with recurrent pterygia averaged 50.5 years of age. One male patient and three female patients had recurrent pterygia. Two of the patients were Swedish and two patients were non-Swedish, according to the study.
