[Persistent corneal defects treated with botulinum toxin-induced ptosis].

OBJECTIVES To evaluate the use of botulinum toxin (BTX) induced ptosis in the treatment of corneal pathology. METHODS We employed two BTX injections into the superior lid of 10 eyes (9 patients). We evaluated the degree of ptosis, its duration and the effect on the corneal lesion. RESULTS Complete ptosis resulted in seven eyes and the corneal pathology resolved in all of them. There were no relevant complications. CONCLUSIONS BTX treatment is a simple and safe technique for treating refractory corneal pathology. It has significant advantages over surgical tarsorrhaphy and is especially useful where the pathology does not require surgery.
