Which abbreviation is used to dose for both eyes?

Explanation:
In ophthalmic dosing, clinicians use Latin abbreviations to indicate which eyes are treated. OU stands for oculus uterque, meaning both eyes. This is exactly what you need when a medication should go in both eyes, so the instruction is clear to apply to each eye. OD and OS represent the right eye and left eye, respectively, so they’re used when only one eye is treated. AU is not the standard for eyes (it’s more commonly seen as auris uterque for both ears in many contexts), so using it for eyes could cause confusion.
