[The Pau phenomenon and complex movements of hyaloid in aphakic eyes].
The author analyzed complex movements of the hyaloid at the height of the ciliary muscle contraction in 121 aphakic eyes. He came to a conclusion that hyaloid dislocation is an active process realized by the ciliary muscle in the course of its contraction. Hyaloid and the vascular coating, on the one hand, and the ciliary muscle, on the other, were shown to be antagonists. Atropine in instillations paralysed the whole muscle, and it was impossible then to detect the predominance of Brücke's muscle over Muller's one. Adrenalin instillations after Gredle or subconjunctivally did not stimulate the contractions of Brücke's muscle, but only those of the vascular coating, for the effects of adrenalin on vascular walls are well known. As for the double innervation of accommodation, it is a fact undeniable, which only confirms that sympathetic innervation performs a trophic function in any tissue, and in the ciliary muscle as well as anywhere else.
