The abbreviation "OU" refers to which part of the body?

The abbreviation "OU" stands for "oculus uterque," which is Latin for "both eyes." This term is commonly used in the field of ophthalmology and optometry to indicate that a treatment, examination, or medication applies to both the left eye and the right eye. This is important in prescriptions or treatment plans, as it clearly communicates that both eyes should be considered or treated equally, especially when dealing with conditions that may affect vision in both eyes simultaneously. In contrast, other abbreviations like "OD" (right eye) and "OS" (left eye) specify individual eyes, underscoring the significance of "OU" in ensuring comprehensive care for both eyes.
