Brief Answer: Anisocoria Detailed Answer: Dear parent, Thanks for the query. The finding is called anisocoria, and needs to be looked further into by an Eye doctor, since the causes range from completely benign such as essential anisocoria (1 out of every 5 persons has this as a normal variant) to more worrisome such as a nerve damage. Hope that helps, wish you the best, Dr Brenes-Salazar MD Mayo Clinic
