A compound named after this structure sees the conversion from cis to trans orientation at the eleventh carbon, and ipRGCs are ganglion cells found in this structure that are sensitive to melanopsin, which helps maintain circadian rhythms. The uvea lies between this entity and the sclera. A region on it that lacks blood vessels is called the fovea centralis, and is also the central portion of the macula. For 10 points, identify this layer of the
