Tropicamide is used to dilate (enlarge) the pupil so that the doctor can see into the back of your eye. It is used before eye examinations, such as cycloplegic refraction and examination of the fundus of the eye. Tropicamide may also be used before and after eye surgery.
As a parasympathetic antagonist, tropicamide exerts its dilatory effects by acting on the pupillary sphincter muscle to cause its relaxation. [10] Like other anticholinergic agents, tropicamide inhibits the parasympathetic drive, allowing sympathetic actions to dominate.
