    Symptom Checker

    Symptom Checker
    Unlike other migraines, ocular migraines (also called "ophthalmic" migraines) involve no pain. Instead, their symptoms include:
    • a growing blind spot, often in the central field of vision;
    • flickering lights or a shimmering zig-zag line; and
    • shades of grey or black across the visual field
    Ocular migraines are created by a neurological response to triggers like hormones, flashing lights, or chemicals found in medications or foods. They generally affect only one eye at a time and go away within 30 minutes. But see your doctor if you experience these symptoms; visual disturbances can be associated with other, more serious disorders.
