In their 2019 paper, “Novel molecular mechanisms for Prph2‐associated pattern dystrophy,” Chakraborty et al use the Phoenix MICRON™ IV retinal imaging platform to longitudinally study the effect of a very specific mutation affecting the Peripherin 2 protein. Peripherin 2 is a protein in rods and cones which, if mutated, can lead to retinitis pigmentosa, cone-rod
In their paper, “The microphthalmia-associated transcription factor (Mitf) gene and its role in regulating eye function,” García-Llorca et al use the Phoenix MICRON™ IV to examine the outer eye appearance, retinal pigmentation, and retinal vasculature through fluorescein angiography to study several different mouse mutants. Combined with electroretinography and histology, the fundus images tell a story
Microglia respond to neurological injury but the precise way they help to clear and remodel the injuries is not known. In their paper, “Optic nerve as a source of activated retinal microglia post-injury,” Heuss et al investigate a population of microglia-like cells that proliferate in the retina after an optic nerve injury. They identify GFPhi myeloid
In a recent well written, compelling article published in Nature Communications, “Endothelial activation of caspase-9 promotes neurovascular injury in retinal vein occlusion,” Avrutsky et al show that caspase-9 inhibition is a promising treatment for retinal vein occlusion. Retinal vein occlusion models hypoxic-ischemic neurovascular damage and is the second leading cause of blindness in working-age adults.
In Nature’s Scientific Reports, Becker et al use the Phoenix MICRON IV, OCT, and focal ERG to assess the therapeutic value of knocking down a splice variant of VEGF in Müller cells in a model of Retinopathy of Prematurity (ROP). ROP is characterized by delayed vascularization of the retina after disrupted oxygen levels, followed by
In the recently published review, “Mouse Models of Inherited Retinal Degeneration with Photoreceptor Cell Loss,” researchers from The Jackson Laboratory in Bar Harbor, Maine and Mahidol University in Bangkok, Thailand performed an extensive literature search to find mouse models of single-gene mutations leading to photoreceptor loss and retinal degeneration. Using the Phoenix MICRON III and
