An adaptive optics vision simulator was used to measure the role of ocular aberrations in the photopic foveal spatial summation curve for three young subjects. After the correction of the ocular aberrations over a 6 mm pupil, the increment luminance threshold was lowered for small stimuli and the estimated area of complete summation (Ricco's area) was reduced by a factor of 2.6 on average. These results show that the image spread due to natural ocular aberrations partly accounts for the spatial summation observed in the fovea in the photopic light regime.
使用自适应光学视觉模拟器测量了 3 名年轻受试者在明视条件下眼像差在光感受野空间总和曲线中的作用。在矫正 6mm 瞳孔范围内的眼像差后，小刺激的增量亮度阈值降低，平均估计的完全总和区域（Ricco 区域）减少了 2.6 倍。这些结果表明，由于自然眼像差导致的图像弥散部分解释了在明视光条件下光感受野中观察到的空间总和。
