What does "OU" stand for in medical terminology?

In medical terminology, "OU" stands for "Both Eyes." This abbreviation is derived from the Latin phrase "oculus uterque," which translates to "each eye." It is commonly used in ophthalmology and optometry to indicate prescriptions, assessments, or treatments that apply to both eyes simultaneously.

Understanding this term is particularly important for caregivers when discussing eye care or interpreting medical instructions related to vision, as it clarifies that the information applies to both eyes instead of just one. Other options represent different anatomical designations, with "Left Eye" and "Right Eye" referring specifically to one eye, while "Both Ears" pertains not to the eyes but to auditory assessments. Thus, "OU" is a specific term that helps convey clear and important information regarding eye care in a clinical setting.
