Definition of Peripheral
Medically reviewed by Min Clinic Staff | Updated: January 2026
Peripheral: Situated away from the center, as opposed to centrally located.
For example, peripheral vision means the type of vision that allows one to see objects that are not in the center of one's visual field.
The word "peripheral" comes from the Greek "peripheria" ("peri-", around or about + "pherein", to bear, carry). An IV (intravenous) catheter is a peripheral line.
