That epithelial cells could still take up debris at all was a surprise, as tissue culture experiments showed that cells missing this integrin were unable to pick up rod cell fragments.

Furthermore, the rod-to-cone cell ratio can be variable even among diurnal species.

The first step in visual perception is absorption of a photon by an opsin pigment in the membranous outer segment of a rod or cone cell.
