Aims: This study was planned to explore the efficacy of autologous blood as a stabilizing agent for graft surgery in pterygium. Material and Methods: For this observational, non-comparative, interventional study, the hospital data of patients who underwent pterygium surgery with autografting using autologous blood between October 2021 to March 2022 were retrospectively analyzed. The graft stability post-surgery and recurrence was studied. There were 37 eyes of 37 patients undergoing pterygium surgery with autograft using autologous serum. The mean age was 53.5 ±10.10 years. Results: Pterygium included were nasal sided primary grade 3 pterygium, double-head pterygium and recurrent pterygium. Postoperatively, there were 4 cases of graft loss (10.8%). The mean time of follow up was 1.8 ±1.4 months (range 1 to 5 months). There was no recurrence seen in patients with graft intact. Conclusion: Autologous blood is a good and cost-effective stabilizing agent for graft surgery in pterygium.
