Prospective Study on Retinal Nerve Fibre Layer Thickness Changes in Isolated Unilateral Retrobulbar Optic Neuritis

Table 1

Comparison of mean RNFL thickness.

	Superior RNFL	Nasal RNFL	Inferior RNFL	Temporal RNFL	Average RNFL
Baseline RNFL in the treatment versus nontreatment eye (𝑃 value)	1.0	0.5	0.8	0.1	0.6
Baseline RNFL in the attack versus fellow eye (𝑃 value)	0.8	0.4	0.9	0.5	0.8
3-month RNFL in the attack versus fellow eye (𝑃 value)	0.2	0.3	0.1	0.02*	0.05*
3-month RNFL in the treatment versus nontreatment eye (𝑃 value)	0.8	0.7	0.9	0.3	1.0
Attack eye RNFL at baseline versus 3 months (𝑃 value)	0.0002*	0.0001*	0.0001*	0.0001*	0.0001*
Fellow eye RNFL at baseline versus 3 months (𝑃 value)	0.1	0.5	0.1	0.4	0.3
