Significant at p <0.05. β =coefficient value. ACD, anterior chamber depth; AL, axial length; BCDVA, best corrected distance visual acuity; PS, posterior staphyloma; SE, spherical equivalent. Other type of staphyloma as the reference when comparing the different groups of PS associated with refractive error.
