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

Table 2

Outcomes for PSB and control patients.

	PSB group; 𝑛=19	Control group; 𝑛=19	𝑃 values
Mean follow-up (mo)	20.47 ± 14.93	16.00 ± 13.01	0.33
Mean final BDVA-grade	2.37 ± 1.07	2.89 ± 1.45	0.22
Mean final logMAR vision score	1.10 ± 0.73	1.38 ± 0.98	0.36
RD	3 (15.8%)	7 (41.1%)	0.14
PVR	1 (5.3%)	5 (38.4%)	0.03
Ocular hypertension	0 (0%)	1 (5.8%)	0.47
Subsequent surgeries	2.11 ± 0.88	1.95 ± 0.97	0.60

PSB: primary scleral buckling; BDVA: best distance visual acuity; logMAR: logarithm of the minimal angle of resolution; RD: retinal detachment; PVR: proliferative vitreoretinopathy.
Continuous and ordinal variables were analyzed using Mann-Whitney test. Binary variables were analyzed using 𝜒² trend test or Fisher’s exact test.
