*All p values are with respect to subfoveal measurements (either CT or LCVT in respective meridian). HSF, horizontal subfoveal; VSF, vertical subfoveal; TM, NM, SM, IM represent temporal, nasal, superior and inferior macular points respectively. T1, T2, N1, N2, N3, S1, S2, I1 and I2 are points of measurements in respective quadrants as depicted in Fig. 1.
