Monochromatic light accentuates details of different retinal layers because of its variable absorption and reflectance by structures both within and above these layers. Monochromatic photography was used to examine macular vitreoretinal interface abnormalities in 19 patients. Short wavelength photographs (490 nm) provided the best detail of inner retinal abnormalities, including epiretinal membranes, vitreoretinal traction, and the internal surface of confluent macular edema (pseudocyst). Although 540-nm red-free photography provided acceptable photographs, it did not provide optimal detail of inner or deep retinal abnormalities. Longer wavelengths, 585 and 610 nm, best disclosed the extent of deep retinal abnormalities, including the extent of confluent macular edema (pseudocysts) and retinal detachment that surrounded macular holes. The addition of short- and long-wave-length photography to traditional red-free photography may provide better localization, understanding, and documentation of the three-dimensional relationships in macular vitreoretinal interface disorders.
单色光因其在视网膜各层及其上方结构中的可变吸收和反射特性，能够突出不同视网膜层的细节。采用单色摄影术对19例患者的黄斑玻璃体视网膜界面异常情况进行了检查。短波长照片（490纳米）能提供视网膜内层异常的最佳细节，包括视网膜前膜、玻璃体视网膜牵拉以及融合性黄斑水肿（假囊肿）的内表面。尽管540纳米无赤光摄影能提供可接受的照片，但它无法提供视网膜内层或深层异常的最佳细节。较长波长（585和610纳米）能最好地显示深层视网膜异常的范围，包括融合性黄斑水肿（假囊肿）的范围以及围绕黄斑裂孔的视网膜脱离情况。在传统无赤光摄影基础上增加短波和长波摄影，可能会更好地定位、理解和记录黄斑玻璃体视网膜界面疾病中的三维关系。
