Abstract

To present a case of bilateral posterior ischemic optic neuropathy (PION) in a patient with uncontrolled Diabetes
Ischemia of the optic nerve that does not involve the optic nerve head is termed posterior ischemic optic neuropathy (PION). It is a rare disorder with a grave prognosis and exact incidence is not known. So far, according to literature very few cases of bilateral PION have been reported.
Case Report: A 54-year-old female with uncontrolled Diabetes Mellitus presented with bilateral profound decrease in vision. Ophthalmological examination with Neuroimaging consisting of MRI of brain and orbits as well as MRA lead to a diagnosis of bilateral PION.
Discussion: PION is a devastating vision threatening condition which can be classified into three types: arteritic PION , non-arteritic PION, and perioperative PION. So far there is no definite treatment for PION, thus preventive measures including control of systemic comorbidities and regular ophthalmic check-up is vital.
