Study Summary

Background: * Blepharospasm is caused by excessive contraction of the muscles that close the eye. It can be treated with injections of botulinum neurotoxin (BoNT), which works by weakening those muscles. * Acetyl Hexapeptide-8 (AH-8) is the active ingredient in a number of cosmetic creams used to treat wrinkles, and is marketed under the trade name Argireline(Copyright). Like BoNT, AH-8 works to weaken the muscles, but is available as a skin cream instead of an injection. AH-8 has never been used to treat people with blepharospasm. Objectives: \- To determine if AH-8 can be used as part of a treatment regimen for blepharospasm. Eligibility: \- Individuals 18 years of age and older who have blepharospasm and have been receiving successful treatment with botulinum toxin injections. Design: * Participants will be involved in the study for a maximum of 7 months. * Patients will have a complete physical and neurological exam, and will be asked questions about their blepharospasm. Patients will then receive BoNT injections in the same areas of the muscle around the eye and at the same doses that have been effective previously. * After the injections, patients will receive a container of either the active cream (with AH-8) or cream without AH-8, and will be instructed on how to apply it. * Patients will return 1 month after the first visit for another neurologic exam and questions, and will be asked about any side effects. Another supply of cream will be given. * Five additional visits will take place on a monthly basis, and patients will be given additional supplies of the cream as needed. Patients will stop participating in the study if they require another BoNT injection for blepharospasm. The study will end after 7 months.

Primary Outcome

The JBRS is a severity scale for blepharospasm, ranging from 0 (no symptoms) to 8 (the most severe symptoms, functionally blind). It includes measures of blink frequency and severity of abnormal eye closure. The scale was measured at baseline (before intervention) and followed over time. Return to baseline value represents loss of benefit from BoNT injection. The time to return to baseline JBRS is an indication of added benefit from the topical intervention.
