Volume and Visual Field Defects in Occipital Stroke: The NOR-OCCIP Study

Table 3

Relation between volume (cc) of occipital infarcts and visual field defects.

		Mean volume (cc)	SD	Median volume (cc)	Interquartile range (IQR)
Normal VF	14	13.8	22.6 (0.4-75)	5.15	1.1-14.0
Mild VFD	15	55.1	130.2 (0.2-508)	9.3	4.1-36.0
Severe VFD	41	43.4	62.6 (0.1-369)	30.1	10.5-48.2
Perimetry missing	9	88.0	89.4 (7.8-296)	50.9	39.6-84.8

VF: visual field; VFD: visual field defect. Acute bilateral occipital infarcts in 7 of the 72 included patients were categorized as two separate infarcts.
