ABSTRACT:
A system for preventing or treating open angle glaucoma and presbyopia by electrical stimulation of the ciliary muscle of the eye. In one embodiment, a body implantable unit develops an electrical stimulation signal and delivers that signal to the longitudinal fibers of the ciliary muscle, to widen the intertrabecular spaces and thereby facilitate outflow of aqueous fluid from the eye, and/or to the circular fibers of the ciliary muscle to accommodate widening of the lens of the eye. The signal developing portion of the implanted unit may include a receiver which cooperates with an external transmitting member or the signal developing portion may be a self-contained pulse generating unit. In a second embodiment, the entire unit is located outside the body and is mounted in a probe shaped holder.
