The John Pratt-Johnson Annual Lecture
Strabismus Horizons
Stephen P. Kraft, M.D., F.R.C.S.C.

This article discusses several new advances in diagnosis, therapy, and basic research in strabismus. Some of these developments are already being applied clinically; many others may be available or accessible in the not too distant future. Orthoptists in both academic and community practice can have important roles to play in these exciting advances.


The diagnostic advances that are reviewed include photoscreening, computer modeling of ocular motility and strabismus, telemedicine, dynamic magnetic resonance imaging, and positron-emission tomography scanning. New treatments on the horizon that are discussed include oral medications for amblyopia, injectable lens substitutes, photorefractive modification of refractive error, early chemodenervation for infantile strabismus, artificial eye muscles, and strategies for regrowing ocular-motor nerves. Finally, progress in understanding abnormal physiology in congenital strabismus, including defects in the vergence and smooth-pursuit systems. is presented.
