a
P-values were obtained by Mann–Whitney's U-test (age, visual acuity, height, tumour horizontal base, distance from posterior tumour margin to fovea, and distance from posterior tumour margin to optic nerve) or Student's t-test (tumour vertical base and largest tumour diameter) as needed.
b
Median.
c
Mean. The bold values indicate P<0.05.
