Was this a TIA or a migraine aura?

age late 30s. female. Saw a silvery line which then proceeded to corner of eye looking like a kalidescope objects in corner of eye. lasted about 8 mins? Also, when I looked at the small black print on laptop screen it looked like some of the letters were partially blacked out. Now, would this be a TIA or a migraine aura. Never had this happen before.
