Abstract
Chalazia and hordeola are the most common lesions occurring in the human eyelid, and often recurrences are managed by surgical intervention to remove fatty inclusions within the lid with associated inflammatory reaction. The present invention provides non-surgical methods of treating chalazia, hordeola and cutaneous infections comprising the administration of compositions comprising botulinum toxin. The present invention provides methods that effectively block meibum secretion from the meibomian glands, reduce sebaceous bacterial culture media on skin, and sebaceous secretion from the glands of Zeis. Decreased production of meibum and associated fatty substances resulting from the methods of the present invention, decrease gland blockage and tissue inspissations, resulting in reduced recurrence of chalazia, hordeola and related inflammatory reactions and lesions.
