Data shown were presented as mean ± SD, Mann-Whitney test, . P value: subthreshold SLT group versus conventional SLT group. IOP: intraocular pressure; CCT: central corneal thickness; D: diopter; : the cup to disc ratio; BCVA: best corrected visual acuity; TM: trabecular meshwork; SD: standard deviation.
