Abstract

Background: Optic neuritis is defined as an autoimmune demyelinating disorder of the optic nerve. It can be idiopathic/post infectious/component of multiple sclerosis. It is not associated with other systemic diseases so commonly. It causes inflammation, which affects the myelin lining of the optic erve. Aim of this study was to identify study the optic nerve characteristics in patients with optic neuritis in a tertiary care center.
Materials and Methods: A descriptive study was done on 30patients with optic neuritis, by considering specific components that determine the optic nerve function. Components of optic nerve studied includes, visual acuity, color vision, contrast ensitivity, visual fields, visual evoked otential and magnetic resonance imaging (MRI).
Results: Optic neuritis is more common in females than males (66.6%). Most common age group is 26-35years (36.6%). Relative afferent pupillary defect (RAPD) seen in 50% of patients (15pts). Visual acuity loss majority in between hand movements–counting fingers close to face (40%). Color vision defects were present in all the patients, Red-Green color defect was more common. Visual fields showed severely depressed fields in 30% patients. MRI was normal in 83% patients.
Conclusion: Optic neuritis usually affects young adults. Proper diagnosis of the disease, correct treatment at right time is necessary. Combined approach for treatment with neurologist is required to make them aware of disease process, treatment & to prevent recurrences.
