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

Table 4

Comparison between the final and the initial BDVA-grade in the control group (𝑛=19). 𝑃 value = 0.96.

Final BDVA-grade (mean: 2.89)	5					2*
	4	1	1	1	2*	2
	3			1*	1
	2	1	1*	1
	1	3*	2
		1	2	3	4	5
	Initial BDVA-grade (mean: 2.84)

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