Evaluation of the Recurrence Rate of Pterygium Excision with conjunctival autograft in 2013-2019 in Nikookari Hospital

Abstract

Pterygium is a common eye disease that is highly prevalent in people living in the tropics. Clinically, in patients with pterygium, proliferation and wing-shaped fibrovascular tissue are visible on the nasal limbus area of the cornea, which functionally leads to exacerbation of astigmatism, decreased visual acuity, and cosmetic problems. This study aimed to investigate the incidence of recurrence of pterygium surgery by free clotting in Tabriz Nikookari Hospital between 2013 and 2019. Materials and Methods: In this cross-sectional study, a full census from 2013 to 2019 was performed on all patients initially subjected to pterygium with autograft transplantation and were admitted to a charity training center. Demographic information of patients, including age, sex, occupation, and place of residence, were extracted from patients' records, and also the date of operation, type of surgery and treatment performed, and the name of the surgeon was recorded for patients to evaluate the recurrence of pterygium surgery which is the main outcome of the study. Results: Out of 120 patients with pterygium, 4 cases were recurrent pterygium, and 116 cases were primary pterygium, the recurrence rate of pterygium in patients with recurrent type was 100%. The incidence of pterygium recurrence was 25%, and the recurrence rate among the surgeons studied was between 10 and 43%. The mean age of our patients was 51.91±12.78 (24-86) years, and there was no difference between the sexes and the age of the patients. 75% of patients were male.
