Age-related macular degeneration affects tens of millions of people worldwide, leading to vision impairment and blindness. Anti-VEGF treatment helps only 25-40% of patients, leaving others with no recourse to this progressive blinding disease. In their article, “Suppression of aberrant choroidal neovascularization through activation of the aryl hydrocarbon receptor,” Choudhary et al explore potential treatment using
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
Retinitis pigmentosa is a genetic disorder that leads to severe vision impairment and blindness. The photoreceptors die off in a self-propelling cycle of rod and cone dysfunction, leading to glial activation and death, leading to more dysfunction. There are a few experimental treatments but no widespread effective treatment or cure. Cassia seed is used in
In the July edition of Nanomedicine journal, Chemla et al demonstrate a fascinating and novel way to label and track individual photoreceptor precursor cells migrating within the retina with fluorescence and gold nanoparticle tagging using the Phoenix MICRON and OCT. Many retinal diseases such as age-related macular degeneration and retinitis pigmentosa are characterized by photoreceptor
