[Technique of inverse scleral flap in the treatment of peripheral corneal defects (Abreu and Delgado technique)]. / Técnica de recubrimiento escleral inverso en el tratamiento de defectos corneales periféricos (Técnica de Abreu y Delgado).

PURPOSE: To present a new easy-to-perform technique for the treatment of peripheral corneal defects (perforation or significant thinning), which has had good results. METHODS: This technique, which consists in sliding and suturing a limbal based inverted scleral flap (similar to the scleral flap used in glaucoma surgery) over the affected peripheral cornea, is described. We present 7 cases: one dellen, two marginal ulcers, two perforating traumatisms, one descematocele and one case of corneal thinning after pterygium surgery. RESULTS: All 7 cases were satisfactorily resolved without modifying either the astigmatism or visual acuity. CONCLUSIONS: This is an easy-to-perform technique which offers good results and although it has some limitations, it can be recommended for the treatment of many peripheral corneal defects (perforations and significant thinning).
