The Outcomes of Primary Scleral Buckling during Repair of Posterior Segment Open-Globe Injuries

Table 3

Comparison between the final and the initial BDVA-grade in the PSB group (𝑛=19). 𝑃 value = 0.02.

Final BDVA-grade (mean: 2.37)	5
	4		1		1*	1
	3			3*	3
	2			4	1
	1	3*	1	1
		1	2	3	4	5
	Initial BDVA-grade (mean: 2.95)

PSB: primary scleral buckling; BDVA: best distance visual acuity.
Analysis was done using Wilcoxon signed-rank test.
