Table 2. Summary of Directional Bias.

Circular means ± circular variance are reported for measurements of the angle of directional bias from each retinal pole. Significance for the determination of whether the angles of directional bias from multiple preparations from a retinal pole deviated significantly from circular uniformity is indicated by asterisks (Rayleigh test). The number of retinas analyzed are given for each retinal pole. * p < 0.05; ** p < 0.01.
