Comparison of conjunctival autograft transplantation and amniotic membrane transplantation for pterygium: a meta-analysis

Abstract

Available trials indicate that CAT has lower recurrence risk compared to AMT for primary pterygium treatment, as well as lower risk of unacceptable appearance risk.

“…Amniotic membrane grafts are very useful in patients with heavily scarred conjunctiva or when a patient may require glaucoma surgery [39,40]. Conjunctival autografts are often favored over the amniotic membrane grafts, as meta-analysis and clinical trials have found higher recurrence rates with the amniotic membrane technique [31,38,39,41,42]. In our results, amniotic membrane grafts had a 19% recurrence rate, while conjunctival autografts had a 16% recurrence rate.…”

Cryopreserved Ultra-Thick Human Amniotic Membrane for Conjunctival Surface Reconstruction After Excision of Conjunctival Tumors

“…3,12,14 Cryopreserved AM is the most commonly used form because it preserves the intact basement membrane and contains a higher amount of soluble, wound-healing modulating factors. 7,15,16 Studies show that it facilitated complete epithelial healing, with good or excellent cosmesis, in patients with ocular surface neoplasia.…”

The Variation in Surgical Technique and Role of Physician Experience in Pterygium Surgical Outcomes

“…Total procedures n = 34 n = 62 recurrence [31,38]. However, the conjunctival autograft is not always the ideal procedure, and the variety of other techniques used in this study reflects this.…”
