title: Clinical measures to promote corneal epithelial healing.
abstract: It is necessary to know the specific pathobiology of a persistent epithelial defect to determine the strategy to be employed to assist in its repair. Lid position and function must be normal and any deficiency in the quantity and quality of the tears enhanced by tear preparations and closure of the lacrimal canaliculi. Adverse drug effects must be eliminated. Multiple corneal punctures and excision of reduplicated basal lamina have virtually eliminated the problem of recurrent corneal erosions. Control of any inflammatory process also speeds healing. Vitamin supplements, especially A, reverse defects associated with xerophthalmia. In any of these diseases, mechanical treatments consisting of soft contact lenses for persistent epithelial defects and collagen shields for the delivery of antibiotics or steroids to the eye may be employed. Tarsorrhaphy relieves the problem of persistent epithelial defects in neurotrophic keratitis and a variety of other conditions characterized by persistent surface breakdown. Preliminary data from open label studies of epidermal growth factors and fibronectin are encouraging but not yet conclusive.
