What does 'OU' represent in medical abbreviations?

The abbreviation 'OU' stands for "Oculus Uterque," which is Latin for "both eyes." In medical contexts, particularly in ophthalmology, this abbreviation is used to indicate that a treatment or observation applies to both of the patient's eyes. It is important for healthcare professionals to clearly communicate the need to administer medications or treatments for both eyes when necessary. Understanding this abbreviation helps avoid confusion and ensures that patients receive the appropriate care.

In contrast, other options pertain specifically to one eye or different time-related instructions, which are not applicable in this case. For example, 'OD' represents the right eye and 'OS' represents the left eye, while 'qAM' is often used to denote "every morning." Knowing these distinctions helps in accurately interpreting prescriptions and instructions.
