Optic disc topographic parameters in normal cynomolgus monkey eyes

Parameters	Right eye		Left eye		Right-left difference
Parameters	Mean	SD	Mean	SD	Mean	SD	As % of mean value for right eye
No significant differences between right and left eyes.
Each value represents mean (SD) for 18 eyes. RNFL, retinal nerve fibre layer.
Right-left difference was calculated using the absolute difference between right and left eyes for each animal.
