1. Pharmacological treatment of strabismus – Strabismus, or misalignment of the eyes, has been treated surgically for centuries. Even in the past 60 years, advances in strabismus treatment have been incremental at best. Unfortunately, surgical outcomes tend to be short-lived, and reoperation is frequently needed. A significant consequence of traditional surgical treatment is the disruption of the normal biomechanical construct – that is, the normal anatomy of the terminal extraocular muscle which moves the eye and the normal relationship of the muscle and the globe itself. In order to minimize these effects, we are investigating new toxins and growth factors that can alter muscle strength without altering the relationship of the muscle and the globe. Preliminary studies show great promise, and next steps include taking these agents to the bedside.
