Results: The muscle of Riolan is a distinct subdivision of striated muscle that is separate from the pretarsal orbicularis muscle. In parasagittal eyelid sections, the muscle appears to be composed of two separate bundles, the pars ciliaris, located anterior to the tarsal plate, and a second smaller bundle, the pars subtarsalis, located ...

Where Is the Gray Line? | JAMA Ophthalmology - JAMA Network
The visualized gray line was consistently seen to correspond histologically to the most superficial portion of the orbicularis muscle, known as the muscle of Riolan. We comment on changes in gray line morphology with lid movement, and we advance a hypothesis to explain its "gray" color.
