Neuro retinitis (NR) though a rare disease occurring in young adults, mostly unilateral is an inflammatory disorder characterized by swelling of optic nerve head and adjoining retinal nerve fibre layer resulting in a typical Macular star configuration due to lipid exudation within macula and fovea. Neuroretinitis can be due to an infectious process involving the disc, a post viral event, of an autoimmune inflammatory mechanism or sometimes idiopathic in nature resulting in a sudden loss of vision in affected eye along with multiple pupillary defects in form of Anisokoria (dilated on affected side), Marcus Gunn pupil or ill sustained pupillary reactions. Patients may also present with painful ocular movements mostly adduction and elevation of the eye. Features common to above all 3 groups included age, absence of pain and fundus findings. Preceding systemic symptoms and visual field loss are more common in patient with Cat scratch disease and Multiple Sclerosis and uncommon in those with recurrences. With today’s technological advances, decision making regarding evaluation and treatment of NR is made accurately to reduce the incidence of optic atrophy which leads to total loss of vision.
