Purpose: : To describe the indications, the surgical procedure and the clinical outcome of MLAM in the treatment of non traumatic corneal perforations and descemetoceles .

Methods: : A prospective, non comparative, interventional case series of eight consecutive patients (mean age 59 years old, 6 men and 2 women) with non traumatic corneal perforations or descemetoceles.The surgery consisted in a MLAM transplantation of a cryopreservated human amniotic membrane. The series included: three active herpetic keratitis, one rosacea, one perforation of an hydrops, one cicatricial pemphigoid, one perforation after an abcess in a corneal graft and one perforation after protonbeamtherapy. The clinical outcome included: the follow-up, the integrity of the eye, corneal epithelialization, inflammation and neovascularization, and the integration of the MLAM. Stromal thickness was followed precisely with the slit lamp. A corneal graft was performed at one patient after the MLAM, allowing microscopic investigation of the removed MLAM integrated in the cornea.

Results: : The mean follow-up was 8.78 months (range 3.57 to 30.17). Amniotic membrane transplantation was successful and reduced inflammation in 7 patients out of 8 ,after one procedure.One patient who presented a large herpetic keratitis epithelial defect with corneal anaesthesia had his MLAM dissolved after two weeks with an aqueous leakage. Epithelium healed within 3 weeks above 7 MLAM and remained stable at 3 months in 7 out of 8 patients. MLAM opacification gradually disappeared over a few months, however, stromal layers filling in the corneal perforations or above the descemetoceles remained stable.

Conclusions: : MLAM transplantation is a safe, effective and useful technique to cure non traumatic corneal perforations and descemetoceles. It can be performed in emergency despite the presence of an active inflammation or infection. By facilitating epithelialization, reducing inflammation and neovascularization, it allows corneal surface reconstruction in patients with persistent epithelial defects and corneal melting that usually ends in a perforation. For full visual rehabilitation, a delayed penetrating keratoplasty is required.
