Septo-optic dysplasia, also known as De Morsier syndrome, is a rare disorder characterized by abnormal brain development. Septo-optic dysplasia causes underdevelopment of the optic nerve, pituitary gland and the septum pellucidum, a middle part of the brain. This condition can cause blindness, nystagmus (dancing eyes), and eyes turned inward or outward.
Currently, the NEI does not have a fact sheet on this condition.
