What does the abbreviation 'OD' typically refer to?

The abbreviation 'OD' is commonly used in medical and optometric contexts to refer to 'Right eye.' This terminology helps healthcare professionals quickly communicate about a patient's ocular health. In a clinical setting, differentiating between the left and right eyes is crucial for diagnosis and treatment, making 'OD' an essential abbreviation for doctors who deal with eye care.

The other options, although relevant in their specific contexts, do not apply to the standard usage of 'OD' within medical terminology related to vision or optometry. For instance, while ocular degeneration and ocular depression pertain to eye health, they would not be abbreviated as 'OD.' Overall dosage is related to medication dosing and administration, which is also outside the scope of this specific abbreviation in eye care.
