Due to this blockage, the accommodative function of the eye that allows vision at different distances is lacking.
As mentioned, cycloplegia is generally induced by drugs that are administered into the eye (eye drops), usually in the context of specialist visits for diagnostic purposes. However, in some cases, cycloplegia could be the result of injury to the third pair of cranial nerves.
In spite of this, only cycloplegia induced by cycloplegic drugs will be considered in this article; in particular, attention will be focused on the latter and their main characteristics.
present in the ciliary body, the lens undergoes a change of shape that allows focusing.
In detail, when the ciliary muscle contracts, the lens takes on an almost spherical shape allowing the focusing of nearby objects.
Cycloplegic drugs are drugs with anticholinergic action, this means that they are able to block the effects of acetylcholine. More in detail, cycloplegic drugs exert this activity by blocking muscarinic receptors, therefore, they are defined as antagonists of the muscarinic receptors.
