What are the sympapomimetics?
These cause mydriasis of the eye by activating the iris dilator muscles via A1 receptors. eg phenylephrine
They can cause arrythmias, hypertension, stinging and don’t work as well in those with diabetes as sugar interferes, or those with a dark iris.
What are the anti muscarinics?
They block the Parasympathetic nervous system so increase mydriasis.
Tropicamide - Short acting
Cyclopentolate - For cycloplegia (stops accommodation) and uveitis

What is used for eye examination to stain the eye?
fluorescein
What is used as an eye anaesthetic?
