What does the abbreviation "ou" stand for in medical terminology?

In medical terminology, the abbreviation "ou" stands for "oculus uterque," which translates to "both eyes." This term is commonly used in prescriptions and medical instructions to indicate that a treatment or medication should be applied to both eyes simultaneously. It is particularly relevant in the context of eye drops, ointments, or any other form of treatment intended for ocular use.

Understanding this abbreviation is crucial for pharmacy technicians, as it ensures proper dispensing and administration of medications when patients have needs that involve both eyes. This knowledge helps avoid medication errors and ensures that patients receive the correct dosage when required for both ocular applications.

The other options relate to different meanings in medical terminology but do not apply to "ou." For instance, "by mouth" is typically abbreviated as "PO," while "left ear" is noted as "AS," and "intrathecal," which refers to delivering medication into the spinal canal, does not have a common abbreviation similar to "ou." Thus, "ou" specifically and accurately refers to both eyes in this context.
