摘要

Noninvasive ocular imaging platforms are undeniably useful in identifying retinal abnormalities. The purpose of this study was to investigate a novel method for integrating information acquired from two independent imaging platforms, AF-SLO and SDOCT, in order to demonstrate retinal perturbations as a result of genetic or pharmacological manipulation. Two cohorts of mice were investigated, Nyxnob and C57BL/6 J. In Nyxnob mice, SLO revealed an atypical but variable amount of autofluorescent foci (AFF); SDOCT showed altered photoreceptor outer segment architecture. Naive Nyxnob had significantly more AFF than C57BL/6 J, suggesting that Nyxnob have some predisposition for developing AFF. Interestingly, both findings were significantly ameliorated in diabetic Nyxnob mice as compared to the controls. These data were incorporated into a novel analysis plot comparing AF-SLO and SDOCT results. The integration of the qualitative changes and accompanying quantitative analysis approach described herein provide a sensitive means for detecting whether a mouse model is susceptible to degeneration before other hallmark indicators are observed.
