Abbreviations: IBT, iodine-125 brachytherapy; RBM, rupture of Bruch's membrane; RD, retinal detachment; TSRWH, transscleral resection performed without hypotensive anaesthesia.
a
P-values were obtained by χ2-test (sex, eye, ciliary body involvement, TNM, exudative retinal detachment, and RBM) or Fisher's exact test (COMS, iris, angle involvement, and visual acuity) as needed.
b
According to COMS classification.
c
According to the ‘T' category of the 7th edition of AJCC staging. The bold value indicates P<0.05.
