ICP measurements in two groups of measured IOP (below and above 20 mmHg)

IOP	n	ICP				P-value
		Mean	SD	Minimum	Maximum
1. Mean IOP ≤ 20	18	187.5	80.9	80	420
2. Mean IOP > 20	6	234.2	69.8	140	330	0.22

Notes: IOP = in mmHg; ICP = in cm H₂O.

Abbreviations: ICP, intracranial pressure; IOP, intraocular pressure; SD, standard deviation.
