What does the abbreviation "OD" refer to in prescription terms?

In prescription terminology, the abbreviation "OD" specifically refers to the right eye. This designation is often used in ophthalmology to indicate which eye a medication is intended for, especially in the context of eye drops or treatments.

Understanding that "OD" stands for "oculus dexter" in Latin is essential; it helps healthcare professionals communicate accurately and avoid medication errors. This is particularly important in cases where medications may be prescribed for conditions that affect one eye but not the other, ensuring patients receive the correct treatment.

The other options, while related to medication and prescriptions, do not accurately represent the meaning of "OD" in this context. For instance, ocular delivery might refer to how medications are administered to the eyes, and oral dosage pertains to how medications are taken by mouth. Overdose indicates taking more than the prescribed amount of a medication, which is a critical concern but not the meaning of "OD." Understanding the correct terminology helps maintain clarity in patient care and medication administration.
