Oral mucosal grafting combined with tenonplasty for ocular surface and lid margin reconstruction in an atypical sectorial chemical burn

A 46-year-old woman presented with chemical injury in both eyes after the instillation of undefined eye-drops prescribed by quack. She had an atypical presentation in the form of bilateral severe necrosis of both lids and whole palpebral conjunctiva. Extensive debridement with conjunctival epitheliectomy, tenonplasty and amniotic membrane transplantation (AMT) was performed. Characteristic differences from typical chemical injuries were a sectorial involvement of ocular surface and keratinisation over distorted lid margins. Lid margin needed replacement by labial mucous membrane for the restoration of ocular surface. Ocular surface reconstruction with AMT in acute phase and mucous membrane grafting for involved lid margins in late phase achieves vision salvage and avoids late complications in drug-induced chemical injury.
