What type of medication delivery does "ophthalmic" refer to?

The term "ophthalmic" specifically relates to the eye. Ophthalmic medications are designed for direct administration into the eyes, often to treat conditions such as glaucoma, infections, or dryness. The formulation can include drops, ointments, or gels, but the key aspect of "ophthalmic" is its connection to the eye as the site of action. Understanding this terminology is critical in medication management, as it helps healthcare professionals specify the correct route of administration and ensure the effectiveness of treatment for ocular conditions.

The other options refer to different routes of drug administration, but they do not pertain specifically to eye treatments. For instance, inhalation involves delivering medications through the respiratory system, and intravenous refers to medications delivered directly into the bloodstream through a vein. Thus, the focus on the eye makes "ophthalmic" the correct designation for this type of medication delivery.
