Ocular Injury	Odds Ratio	95% Confidence Interval	P value
Globe rupture	1.088	0.131–9.031	0.027
Retinal Detachment	11.268	1.929–65.801	0.000
Optic nerve damage	6.388	0.819–49.809	0.007
Choroidal injury	11.268	1.929–65.801	0.000
Vitreous hemorrhage			0.001
Globe penetrating			0.539
Initial Visual Acuity			0.000

Univariate statistic testing by qi-square compared final BCVA worse than 20/200 versus final BCVA better than 20/200. P value < 0.05 was considered statistical significance. Binary logistic regression statistic was performed followed qi-square test, OR>1 indicates negative factor for prognosis of visual acuity
