Which abbreviation indicates the right eye?

The abbreviation that indicates the right eye is "O.D.," which stands for "oculus dexter" in Latin. In the context of medical terminology, "oculus dexter" specifically refers to the right eye, allowing healthcare professionals to clearly document and communicate eye-related prescriptions or treatments.

Understanding these abbreviations is crucial for medication aides, as misinterpretation could lead to administering medications improperly. The other options refer to different terms: "O.U." stands for "oculus uterque," meaning both eyes; "O.S." stands for "oculus sinister," which refers to the left eye; and "p.o." means "per os," which indicates oral administration of medication and does not relate to eye designations at all. Therefore, recognizing "O.D." as the abbreviation for the right eye is essential in ensuring accurate communication in medical settings.
