Case Reports
[A clinico-pathological case report of necrotizing ulcerating keratopathy due to topical anaesthetic abuse].
Topical anesthetic abuse is rare, but difficult to diagnose since most patients deny its use and the clinical changes are very similar to other corneal diseases. ⋯ Topical anesthetic abuse can mimic different corneal diseases and be difficult to diagnose if the patient denies its use. In cases of keratitis with no response to treatment and strong ocular pain, topical anesthetic abuse should be considered.

Severe thermal and chemical burns may result in limbal deficiency leading to persistent epithelial defects, complete conjunctival epithelial ingrowth and vascularisation of the cornea. If sufficiently severe, these burns may lead to very significant visual impairment. Amniotic membrane transplantation with limbal transplantation has recently been proposed as a new method for corneal surface reconstruction. ⋯ Amniotic membrane transplantation with limbal transplantation allows reconstruction ocular surfaces severely damaged by chemical or thermal burns. In most cases, however, additional surgical procedures such as lamellar or penetrating keratoplasty are required for adequate visual rehabilitation.
