Modeling Hypertension as a Contributor to Retinal Hemorrhaging from Abusive Head Trauma

Table 9

Stress and displacement change percentage for the POIs and average for the ex vivo RH experimental model and the TBI and abusive shaking TBI models.

		POI1 (%)	POI2 (%)	POI3 (%)	POI4 (%)
von Mises stress change	Ex vivo RH experimental model	44	42	35	37	Maximum displacement change percentage
	TBI mean blood pressure model	22	28	12	18
	Nonhypertensive shaking model	15	20	7	14
	Abusive shaking AHT model	38	50	13	26
Volumetric strain change	Ex vivo RH experimental model	40	41	40	40
	TBI mean blood pressure model	27	27	29	27
	Nonhypertensive shaking model	16	17	21	21
	Abusive shaking AHT model	45	47	52	54
Displacement change	Ex vivo RH experimental model	40	52	49	53	48%
	TBI mean blood pressure model	31	32	36	37	34%
	Nonhypertensive shaking model	9	20	34	36	NA
	Abusive shaking AHT model	45	57	81	87

Values in italics indicate that the computed values exceed the computed experimental increase required to cause RH.
