Aims: To define the effect of the neuropeptides substance P, calcitonin gene related peptide, vasoactive intestinal polypeptide, neuropeptide Y, and secretoneurin on the proliferation of human retinal pigment epithelial (RPE) cells.

Methods: ARPE-19 cells were used. The cells were cultured in Dulbecco's modified Eagle's medium.
