Assessment of the Human Retinal Neural Selectivity to Square Gratings’ Orientation with the Multifocal and Pattern Electroretinograms

The retinal response to particular orientations might start a signaling cascade of events that help modulate eye growth and respond myopia control treatments. purpose this study was investigate the electrical activity in grids different spatial orientations. multifocal (mfERG) pattern (PERG) ERG responses nine eyes (spherical equivalent −0.45 ± 1.15 D; mean age 32.9 7.7 years) were recorded with four (1.2 cpd) oriented at 60°, 90°, 120° 180° under pupils’ dilation. mfERG analyzed by eccentricity, quadrants meridians same orientation grids. density mfERG, amplitudes PERG implicit times each peak from both tests analyzed. grid’s did not evoke tests. All showed higher parallel meridian lower perpendicularly These differences statistically significant horizontal 60° (p < 0.050). change grids’ sensitive detect changes outer variations stimulus orientation. paradigm meridional analysis results be more than traditional rings, or hemifields.
