A diverse range of retinal specializations are examined in twelve species of reef teleosts and estimates of the spatial resolution of neurons within the ganglion cell layer calculated using Matthiessen's ratio. Upper limits of between 4 and 27 cycles per degree were found to facilitate acute vision into frontal and eccentric space, utilizing temporal and nasal area centralis, respectively. Upper limits of between 3 and 20 cycles per degree were found in horizontal areas of acute vision across the retinal meridian. These areas are thought to be used for panoramic vision and may, in one species, indicate the relative importance of this region in comparison to the temporal area centralis. Comparisons are made between ganglion cell acuity and other morphological and behavioural acuities calculated in previous studies.
在12种珊瑚礁硬骨鱼中研究了多种视网膜特化，并使用马蒂森比率计算了神经节细胞层内神经元的空间分辨率估计值。发现每度4至27周的上限有助于分别利用颞侧和鼻侧中央区实现对额部和偏心空间的敏锐视觉。在横跨视网膜子午线的急性视觉水平区域发现每度3至20周的上限。这些区域被认为用于全景视觉，并且在一个物种中，可能表明该区域与颞侧中央区相比的相对重要性。还对神经节细胞敏锐度与先前研究中计算的其他形态学和行为敏锐度进行了比较。
