It's a common misconception. What you're calling "ocular migraines" are more accurately referred to as "migraines with aura without headache", sometimes called "silent migraines". You can get actual ocular migraines as well, but those affect the eye (or optic nerve), and as such, are limited to the eye. Scintillating scotomas caused by migraine auras are visible with your eyes closed, and look the same in both eyes.
