Abstract

Introduction  On the basis of analogy with other autonomically innervated muscles, the ciliary body should have a sympathetic as well as a parasympathetic nerve supply. Although there is wide acceptance of such a dual innervation, the distribution of the nerve elements in the ciliary muscle is controversial. Much clinical and experimental investigation has been performed in an attempt to resolve this controversy.Henke,1 in 1860, postulated that the circular and longitudinal fibers of the ciliary muscle had opposing actions in accommodation, a hypothesis that Warlomont2 agreed with on the basis of his anatomic studies on human and animal eyes. In 1891, Morat and Doyon,3 working with animal eyes (dog, cat, and rabbit) suggested that the sympathetic system was related to distance accommodation by inhibiting the ciliary muscle, while the parasympathetic system was active in near accommodation. The concept of reciprocal innervation was again proposed by Henderson,4
