Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. [15] Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ...
Tropicamide, sold under the brand name Mydriacyl among others, is a medication used to dilate the pupil and help with examination of the eye. [3] Specifically it is used to help examine the back of the eye. [4] It is applied as eye drops. [3] Effects occur within 40 minutes and last for up to a day. [3]
In difficult cases, "cycloplegic agents are highly favored to break spasm quickly and may be more economical compared to other conventional therapies" [3] Cyclopentolate, Atropine, Tropicamide, and Homatropine are the typical cycloplegic eye drops used once daily to treat spasm of accommodation by relaxing the ciliary muscle. One side effect is ...
A lower resting heart rate or slower heartbeat will fill the ventricles/heart better and allow for more of a forceful contraction of blood out to the rest of the body, says Dr. Weinberg.
[17] [18] [15] Belladonna drops act as a muscarinic antagonist, blocking receptors in the muscles of the eye that constrict pupil size. [57] Belladonna is currently rarely used cosmetically, as it carries the adverse effects of causing minor visual distortions, inability to focus on near objects, and increased heart rate.
[103] [104] These treatments include pirenzepine gel, cyclopentolate eye drops, and atropine eye drops. While these treatments were shown to be effective in slowing the progression of myopia and reducing eyeball elongation associated with the condition, side effects included light sensitivity and near blur.
Hydroxyamphetamine is used in eye drops to dilate the pupil (a process called mydriasis) so that the back of the eye can be examined. This is a diagnostic test for Horner's syndrome . Patients with Horner's syndrome exhibit anisocoria brought about by lesions on the nerves that connect to the nasociliary branch of the ophthalmic nerve . [ 7 ]
It is used as a medication to reduce pressure inside the eye and treat dry mouth. [1] [5] As an eye drop it is used to manage angle closure glaucoma until surgery can be performed, ocular hypertension, primary open angle glaucoma, and to constrict the pupil after dilation.
