通过眼底检查和摄影，可以连续检查和记录活的蟾鱼(Opsanus Tau)眼睛从暗适应状态到光适应状态的时间相关变化。在目前的研究中，完全暗适应的眼睛几乎没有显示脉络膜、色素上皮或视网膜血管细节。视神经呈白垩白，边界模糊。视网膜条纹从视神经向外辐射，呈灰褐色到白垩白。随着光线适应的开始，视网膜条纹消失，视网膜血管系统以及潜在的脉络膜和色素上皮细节变得更加清晰。一旦眼睛完全适应了光线，下面的色素上皮和脉络膜就可以看到典型的橙色和黑色斑驳的地理外观，视神经头部出现粉红色，有明显的边界。即使在完全适应光线的眼睛中，也可以看到一条模糊的线条从视神经延伸出来。这真是太棒了。
Intraocular funduscopy and photography permitted serial examination and documentation of time-related changes in the living toadfish (Opsanus tau) eye as it went from the dark-adapted to the light-adapted state. In the present study, the fully dark-adapted eye showed virtually no choroidal, pigment epithelial, or retinal vascular detail. The optic nerve was chalky white with indistinct borders. Grayish brown to chalky white retinal streaks radiated from the optic nerve into the periphery. As light adaptation began, the retinal streaks faded, with the retinal vasculature and the underlying choroidal and pigment epithelial detail becoming more discernible. Once the eye became fully light adapted, the typical geographic orange and black mottled appearance of the underlying pigment epithelium and choroid was visible, and the optic nerve head developed a pink hue with a distinct border. Even in the fully light-adapted eye, a vague radiation of lines could be seen extending from the optic nerve. This was superi...
