0 one of the muscles around the lens of the eye that can change the shape of the lens in order to produce a clear image -- 睫状肌（晶状体周围的一块肌肉，作用是改变晶状体形状以获得清楚的映像）
There will be no response to accommodation the "ciliary muscle" is also paralyzed.
When the ciliary muscle contracts, it opens the trabecular meshwork through increased tension on the scleral spur.
When the ciliary muscle contracts, it pulls itself forward and moves the frontal region toward the axis of the eye.
Exceedingly small changes in axial length of the eyeball (18.619.2 micrometres) are caused by the action of the ciliary muscle during accommodation.
The ciliary muscle is also more massive than the constrictor pupillae, again by a factor of twenty.
Some parasympathetic light-reaction neurons that were originally destined for the iris sphincter will end up innervating the ciliary muscle.
With administration of a ganglion-blocking drug, the ciliary muscle can not contract (cycloplegia) and the patient loses the ability to focus their eyes.
Accommodation and vergence are also known as the near response, while inhibition of the ciliary muscle is also known as the far response.
