Scatter plots showing the relationship between the severity of parafoveal scotoma and tilt ratio. (a, d) The relationship between central average TD (a) and parafoveal average TD (d) values and tilt ratio in 99 early myopic NTG eyes. (b, e) The relationship between central average TD (b) and parafoveal average TD (e) values, and tilt ratio in 50 early myopic NTG eyes without significant optic disc rotation. (c, f) The relationship between central average TD (c) and parafoveal average TD (f) values, and tilt ratio in 49 early myopic NTG eyes with significant optic disc rotation. P-values for all linear and quadratic regression are presented.
