Aim: To evaluate the outcomes of pterygium excision with conjunctival autograft using autologous in situ
blood coagulum.
Materials and Methods: This is a prospective study of 50 eyes of 50 patients after taking informed
consent, operated between May 2017 and October 2018 in the Department of Ophthalmology, Narayana
Medical Hospital, Nellore. The study included 21 males and 29 females. Following pterygium excision, 1
mm oversized donor conjunctival graft was taken and placed over bare sclera, maintaining limbus to limbus
polarity. The surgeon waited for 5-7 minutes to allow time for hemostasis and stabilization of graft.
Results: Complications observed were graft edema in 4 cases (8%), graft retraction in 1 case (2%), subgraft
haemorrhage in 2 cases (4%). Commonly encountered complications were subconjunctival haemorrhage,
chemosis, congestion, discomfort, corneal scarring, corneal epithelial defects, and inadequate sized grafts.
Recurrence or dehiscence w ere not noted.
Conclusion: This study of using autologous blood coagulum for pterygium fixation showed this method to
be more effective, less time consuming than suturing grafts, and more economical and free from the risk of
contagious diseases compared to fibrin glue. The occurrence of very minimal complications and the swift
resolution of any encountered complications makes this a superior approach.
