Anisocoria: Anisocoria refers to unequal pupils. Physiologic anisocoria is very common and normal in up to 20% of people. The variation should be no more than 1mm and both eyes should react normally to light. It can be dangerous if it is a form of horner's syndrome (e.g. Carotid dissection) or from damage to the third nerve (e.g. Aneurysmal expansion) so you should get it checked out!

Unless you went to: Eye doctor and he administered eye drops to dilate your pupils, this is a dangerous sign of brain damage. Get to emergency dept of your nearest hospital right away.
