Sažetak
It has been shown that amniotic membrane transplantation (AMT) improves healing of the epithelium defects as it serves as a basement membrane for endothelial cells growth, prevents inflammatory cell infiltration and reduces apoptosis in keratocytes. Having in mind the healing properties of AM we investigated the efficacy of AMT in persistent epithelial defect (PED) on the corneal graft. 80 corneal grafts were prospectively followed up for presence of PED 10 months after surgery. PED was detected in 12 cases (15%) having surgery for: rejected graft (n=4), keratoconus (n=3), keratoconus following PK on a second eye (n=3), corneal perforation (n=1) and Stevens-Johnson keratopathy (n=1). Epithelial defect (ED) developed 14±7 days after surgery in 10 cases and 1,5 month in other two. All patients were primarily conservatively treated with subconjuctival steroids and artificial tears for 10 days and systemic steroid therapy if needed after, until the period of 2 weeks. 4 patients were healed. Since ED was unresponsive to all previous treatments for more then 2 weeks, one layer of AM was placed on the corneal lesion in 5 patients, and in 3 cases of deep PED several layers of AM were placed. Healing of the defect was obtained in 7/8 (87.5%) eyes. In 1 patient second AM transplantation was necessary. Mean epithelization time was 2 weeks (range 1–3 weeks) in monolayer and 3 weeks (range 2–4 weeks) for multilayer cases. 5 out of 8 patients retained the same best corrected visual acuity (BCVA) while 3/8 patients improved their vision more than 2 lines. Preoperative corneal thickness of 255±40 mm increased to 455±90 mm. AM transplantation facilitates healing of corneal epithelium. PED on the corneal graft unresponsive to conventional treatment can be effectively cured when covered with one or more amniotic membrane layers.
