The distribution of toxic metals in the human retina and optic nerve head: Implications for age-related macular degeneration.

PLoS ONE, 2020
ObjectiveToxic metals are suspected to play a role in the pathogenesis of age-related macular degeneration. However, difficulties in detecting the presence of multiple toxic metals within the intact human retina, and in separating primary metal toxicity ...

Single‐Cell Annotation and Localization via Integrating Spatial Transcriptomics Maps the Mouse Ocular Atlas and RAO Dynamics

Advanced Science, EarlyView.
We developed the ASCAL pipeline, integrating complementary spatial transcriptomics, to construct a high‐fidelity mouse whole‐eye single‐cell atlas. Applying ASCAL to a retinal artery occlusion (RAO) model revealed spatially restricted immune activation localized to the ganglion cell layer and the selective depletion of a translationally active, outer ...

ApoE‐ and Cfh‐deficient mice exhibit structural and molecular features of human early–intermediate retinal degeneration

Animal Models and Experimental Medicine, EarlyView.
Age‐related macular degeneration (AMD) involves lipid dysregulation and complement overactivation. Here, we characterize a double‐knockout ApoE−/−/Cfh−/− mouse as a model of early–intermediate retinal degeneration. These mice exhibit retinal pigment epithelium thinning, Bruch's membrane thickening, lipid accumulation, enhanced C5b‐9 deposition ...

Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.

Novel rodent models for macular research [PDF]

, 2010
BACKGROUND: Many disabling human retinal disorders involve the central retina, particularly the macula. However, the commonly used rodent models in research, mouse and rat, do not possess a macula.
