Does atropine cause mydriasis?

Who should not use atropine eye drops?

Does atropine increase eye pressure?

What is the effect of pilocarpine in the eye and its purpose?
Ophthalmic pilocarpine is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Pilocarpine is in a class of medications called miotics. It works by allowing excess fluid to drain from the eye.
What effects will the atropine sulfate injection have on the eye and vision?
Atropine ophthalmic can be placed into the stronger eye to temporarily blur the vision in that eye. This helps strengthen the weaker eye because the brain will force that eye to work harder to focus. Atropine ophthalmic may also be used for purposes other than those listed in this medication guide.

Does atropine lower eye pressure?
Intraocular pressure and pupil diameter were measured prior to and during a 2-day period of treatment with 1% atropine sulfate. No significant changes in intraocular pressure occurred as a result of the treatment with atropine. Pupil diameter increased significantly after atropine was applied.
How does atropine affect the developing retina?
Acetylcholine is involved in the developing retina, and when atropine is given as an eye drop it blocks the action of acetylcholine at the muscarinic receptors which is postulated to be a mechanism by which atropine can slow eye growth and myopia progression. 4 Atropine’s ocular side effects are well known.
