[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.
