What is an ocular migraine?

An ocular migraine is primarily characterized by the presence of visual disturbances or phenomena, which can occur with or without a headache. This visual experience can include symptoms such as flashing lights, zigzag lines, or even temporary vision loss in one eye. While it is associated with migraine types, the defining factor is the visual component rather than the headache itself.

This option accurately captures the essence of an ocular migraine, aligning with clinical definitions and descriptions. In many cases, individuals may experience these visual symptoms without any accompanying headache or pain, which reinforces that the presence of visual phenomena is a key characteristic of an ocular migraine. It is important to differentiate that while headaches and visual disturbances can coexist, the visual component is the hallmark feature of this type of migraine.
