In fact, similar changes were reported in other animal models of RPE degeneration, including sodium iodate [7] and ornithine-induced models [10] and the ornithine delta-aminotransferase deficient mouse [11], and a similar scenario also has been invoked as a mechanism in human dry AMD [2,3] and gyrate atrophy [4].
Although there are no reports about the mode of RPE cell death in human gyrate atrophy with hyperornithinemia, necrosis of RPE cell was observed in ornithine-induced retinopathy in rats [10].
Further studies to evaluate spermidine concentrations and amine oxidase activity in patients with dry AMD and gyrate atrophy are needed to clarify this point.
Although the effect of spermidine on the inner retina was not fully clarified, following further validation, this novel animal model will likely be not only useful for elucidating the pathophysiology of dry AMD and gyrate atrophy, but also useful for screening potential therapies for these diseases.
