Abstract
Purpose: To study the retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) changes on optical coherence tomography in early multiple sclerosis (MS) patients. Methods: A prospective cohort study was conducted at a tertiary care center. Patients of early MS (expanded disability status scale P < 0.05). All the visual parameters significantly correlated with GCL + IPL thickness. Conclusion: GCL + IPL thickness is a more sensitive clinical structural marker than RNFL in early MS with/without ON and ON patients and correlates with all the visual parameters better than RNFL thickness.
