作者使用红外视频瞳孔描记术检查了早产儿对红色和蓝色刺激的瞳孔光反射。瞳孔对光反射的反应，获得470 nm的蓝色和635 nm的红色刺激与不同强度的10 cd/m（2）和100 cd/m（2）。红色刺激未引起早产儿瞳孔反应。然而，蓝色刺激产生瞳孔反射，反应的程度取决于刺激的强度。这些结果表明，在早产儿中，光反射的起源可能主要由含有黑视素的视网膜神经节细胞介导。
The authors examined pupillary light reflexes to both red and blue stimuli using infrared video-pupillography in premature infants. Pupillary light reflexes were obtained in response to 470 nm blue and 635 nm red stimuli with varying intensities of 10 cd/m(2) and 100 cd/m(2). Red stimuli did not evoke a pupillary response in premature infants. However, blue stimuli produced a pupillary reflex, and the extent of the reaction was dependent on the intensity of the stimulus. These results suggest that in premature infants, the origin of light reflex may be mediated predominately by melanopsin-containing retinal ganglion cells.
