Table 2 Comparison of the macula OCT and optic nerve data between 50 IGHD and 50 controls eyes. Data are expressed as mean (standard deviation), and compared by Student’s t test, except for the inferior quadrant and the cup area expressed as median (interquartile range) and compared by Mann–Whitney test
