Causes pupil dilation which may help break or prevent posterior synechiae formation. Causes relaxation of the ciliary muscle which can deepen the anterior chamber.

Atropine IV/IM (Atropisol, Atropair, Isopto)

Acts at parasympathetic sites in smooth muscle to block response of sphincter muscle of iris and muscle of ciliary body to acetylcholine, causing mydriasis and cycloplegia. Phenylephrine (2.5% or 10% solution) concurrently with atropine may prevent formation of synechiae by producing wide dilation of pupil.
