| abstractText | An appropriate animal model is essential to screening drugs or designing a treatment strategy for geographic atrophy. Since oxidative stress contributes to the pathological changes of the retinal pigment epithelium (RPE), we are reporting a new mouse AMD model of retinal degeneration by inducing mitochondrial oxidative stress in RPE. Sod2 the gene for manganese superoxide dismutase (MnSOD) was deleted in RPE layer using conditional knockout strategy. Fundus microscopy, SD-OCT and electroretinography were used to monitor retinal structure and function in living animals and microscopy was used to assess pathology post mortem. Tissue specific deletion of Sod2 caused elevated signs of oxidative stress, RPE dysfunction and showed some key features of AMD. Due to induction of oxidative stress, the conditional knockout mice show progressive reduction in ERG responses and thinning of outer nuclear layer (ONL) compared to non-induced littermates. |
