Notemigonus crysoleucas organisms were exposed to light at 1,250 and 850 lux in regimes of 12L:12D and 24L:OD. Each layer of cells in the retina was evaluated employing light microscopy and measurements for quantitative analysis were recorded from the retinas of over 150 fish. These values were compared for dorsal and ventral portions of the retina, for the two intensities, and for the two regimes. Fish maintained under the 24L:OD light regime exhibited significant light damage to the retina, characterized by reduction of outer segments of photoreceptors, reduction in the density of nuclear layers, and disintegration of ganglion cells. The dorsal portion of the retina experienced significantly greater deterioration than the ventral portion. Fish which had been subjected to 96 hours of continuous light displayed no ability to repair damage after 96 hours under 12L:12D.
将角突丽脂鲤置于12小时光照：12小时黑暗和24小时光照：0小时黑暗的条件下，分别暴露于1250勒克斯和850勒克斯的光照中。使用光学显微镜对视网膜的每一层细胞进行评估，并从150多条鱼的视网膜中记录用于定量分析的测量值。对视网膜的背侧和腹侧部分、两种光照强度以及两种光照条件下的这些值进行了比较。处于24小时光照：0小时黑暗光照条件下的鱼，其视网膜表现出明显的光损伤，特征为光感受器外段减少、核层密度降低以及神经节细胞解体。视网膜的背侧部分比腹侧部分恶化得更明显。连续光照96小时的鱼在12小时光照：12小时黑暗条件下96小时后没有修复损伤的能力。
