Alzheimer’s Disease (AD) is a progressive neurodegenerative disease that severely impacts quality of life, so biomarkers that help identify AD are highly sought after. Here, we investigated the retinas of APPSL and 5xFAD mouse models and wild-type littermate controls, provided by QPS Austria GmbH, using a custom optical coherence tomography (OCT) ophthalmoscope. Features of interest including retinal thickness, the visibility of the photoreceptor inner and outer segment junction, and vessel density were quantified from the OCT images, with a number of significant differences between groups. This study identifies potential AD biomarkers and reemphasizes the importance of using proper age-matched controls.
