This prospective and comparative study aimed to compare the use of a conjunctival autograft (CAG), plasma rich in growth factors fibrin membrane (mPRGF) or amniotic membrane transplantation (AMT) in primary pterygium surgery. Patients were assigned for surgery with CAG (group A), mPRGF (group B), or AMT (group C). Pterygium recurrence, Best Corrected Visual Acuity (BCVA), graft size (measured with anterior segment optical coherence tomography (AS-OCT)), and ocular surface symptoms (visual analogue scale (VAS) and ocular surface disease index (OSDI)) were evaluated. Thirteen eyes in group A, 26 in group B, and 10 in group C were evaluated. No changes in BCVA (p > 0.05) were found. Recurrence cases for groups A, B, and C were none, two, and two, respectively, and three cases of pyogenic granulomas in group A. The horizontal/vertical graft size was lower in group B vs group A (p < 0.05) from months 1 to 12. The improvement in VAS frequency for groups A, B, and C was: 35.5%, 86.2%, and 39.1%, respectively. The OSDI scale reduction for groups A, B, and C was: 12.7%, 39.0%, and 84.1%. The use of the three surgical techniques as a graft for primary pterygium surgery was safe and effective, showing similar results. The mPRGF graft represents an autologous novel approach for pterygium surgery.

ABSTRACT Purpose To compare two techniques of human amniotic membrane transplantation (AMT) following pterygium excision: (1) end to end suturing of the amniotic membrane graft (AMG) with the conjunctiva versus (2) a new technique of purse-string suturing of the AMG and tucking of AMG under the free edge of conjunctiva. Materials and methods Pterygium surgery with human AMT was done in 42 eyes with primary pterygium. Twenty four eyes (group A) underwent end-to-end suturing of AMG with conjunctiva. Eighteen eyes (group B) underwent purse-string suturing of AMG with underlying sclera with free edge of AMG tucked under conjunctiva on three sides. The two groups were compared in terms of the outcome measures, i.e. complete epithelialization time of AMG and recurrence of pterygium within 1 year. Results The complete epithelialization of AMG occurred in 21 days (range 14 to 28 days) and 14 days (range 7 to 21 days) in groups A and B respectively. In group A, 7 eyes (29.17%) developed recurrence. In group B, 2 eyes (11.11%) developed recurrence. Conclusion Purse string suturing and tucking of AMG resulted in faster epithelization of AMG and lower recurrences in comparison with end to end suturing of AMG in the management of primary pterygium.
