Answer:
Botulinum Toxin
Explanation:
Botulinum Toxin is a neurotoxin (meaning that its target is the nervous system) produced by a bacteria known as Clostridium Botulinum. The Botulinum Toxin inhibits the transmission of acetylcholine (principal neurotransmitter that participates in muscle contraction). The acetylcholine travels from presynaptic motor neurons (the neurons that control the movement) to the muscle at the neuromuscular junction (the place where the nerve gets in contact with the muscle) interfering with neural transmission and inhibiting the stimulation of the muscle fiber, thus causing muscle paralysis.

Answer: the person with cycloplegia will have difficulty with near vision.
Explanation: Cycloplegia is the paralysis of the ciliary muscle which leads to loss of accommodation ( that is, loss in the ability to focus on an object as the distance varies) this occurs with topical application of atropine. Ciliary muscle is a smooth muscle at the vascular layer of the the eye that controls the shape of the lens.
Atropine is a cycloplegic drug that is used by eye doctors during eye examination to:. - better visualize the retina and to
-determine the true refractive error of the eye. This application by the doctor wears off with hours after the eye examination.
Paralysis of this muscle can lead to inability to adjust the curvature of the lens to focus on nearby objects. I hope this helps. Thanks.
