Item Comparación del uso de la membrana amniótica frente al autoinjerto de conjuntiva en cirugía ocular: Revisión bibliográfica(Universidad Santiago de Cali, 2024) Cuellar Urrutia, Laura Camila; Palomino Suarez, Nicolle Dahyan; Valencia Becerra, Evelyn; Segura Castillo, Linda NeriethIntroduction: Pterygium, also known as "surfer's eye", is a benign lesion characterized by an abnormal fibrovascular growth taking a triangular or wing shape, composed of an epithelium and loose subepithelial connective tissue, limbal and conjunctival tissue largely vascularized. Objective: To compare the use of amniotic membrane versus conjunctival autograft in pterygium resection surgery, based on results of clinical cases. Materials and methods: A search was performed based on studies taken from the following databases accompanied by the respective number of articles used in the tracking matrix, starting with Pubmed (28), Web of Science (17), Google Scholar (11), ScienceDirect (8), Scopus (8), Dialnet (4), Nature (2), Taylor & Francis Group (1) and Springer Link (1). Results: Studies have shown that the combination of MA with antifibrotic agents such as mitomycin C can reduce the recurrence rate to 10-15%, approaching the results obtained with conjunctival autograft, but the use of MA alone can lead to higher recurrence rates; this has generated an interest in optimizing fixation techniques and adjuvant treatments to improve long-term clinical results. Conclusion: Both techniques have been shown to be effective in reducing pterygium recurrence; however, conjunctival autograft is distinguished by its ability to offer a lower long-term recurrence rate; this finding reinforces the relevance of selecting the most appropriate surgical technique based on the characteristics of the pterygium and the particularities of each patient.
