Cycloplegia

Cycloplegia is the paralysis of the ciliary muscle, resulting in a loss of accommodation, resulting in pupil dilation.

Cycloplegic drugs, including atropine, cyclopentolate, succinylcholine, homatropine, scopolamine and tropicamide, are indicated for use in cycloplegic refractions and the treatment of uveitis. Other cycloplegic drugs include Neostigmine, Phentolamine and Pilocarpine.

Unlike mydriatics, which also dilate the pupil, cycloplegic drugs inhibit focusing.
