WebThe mean age (SD) was 9.16 (1.7) years and the mean (SD) RNFL average thickness was 98.46 (10.79) μm. The temporal quadrant showed the thinnest RNFL (69.35±11.28 μm), followed by the nasal (71.30±13.45 μm), superior (123.65±19.49 μm) and inferior (130.18±18.13 μm) quadrants. WebOCT evaluates the optic nerve axonal integrity by measurement of the retinal nerve fiber layer (RNFL), and is generally used to evaluate for evidence of prior ON. The pattern of RNFL thinning most specific to MS is temporal.3 RNFL can appear normal in the acute setting but starts to decline within 4 weeks of ON.
