Designer Leptin Receptor Antagonist Allo-aca Inhibits VEGF Effects in Ophthalmic Neoangiogenesis Models
Experimental and clinical data suggest that pro-angiogenic, pro-inflammatory and mitogenic cytokine leptin can be implicated in ocular neovascularization and the other eye pathologies. At least in part, leptin action appears to be mediated through functional interplay with vascular endothelial growth factor (VEGF). The effects of VEGF on leptin expression were assessed in ocular endothelial cell…
Retinal Ischemia Tied to Variant of Acute Macular Neuroretinopathy
Paracentral acute middle maculopathy is a newly identified variant of acute macular neuroretinopathy that appears to result from retinal capillary ischemia, according to a retrospective observational case series. “This has been traditionally a very rare disease but now with advanced retinal imaging systems such as spectral domain optical coherence tomography (SD-OCT) and infrared reflectance imaging…
Interim results from clinical trial demonstrate safety of cell-based therapy for retinitis pigmentosa
Regenerative medicine company jCyte and the Sue & Bill Gross Stem Cell Research Center at the University of California, Irvine report that their investigational therapy for retinitis pigmentosa (RP) has demonstrated a favorable safety and tolerability profile in an ongoing Phase I/II clinical trial. The cell-based approach taken is intended to rescue sick and dying…
New Trial Shows Drugs are Effective for Diabetic Macular Edema
Diabetes is a significant risk factor for developing eye diseases. The most common diabetic eye disease and a leading cause of blindness is diabetic retinopathy. Americans with diabetic retinopathy have diabetic macular edema (DME) in which fluid leaks into the macula, the area of the retina used when looking straight ahead. Over the past few…

Gut microbes linked to major autoimmune eye disease
One major cause of human blindness is autoimmune uveitis, which is triggered by the activation of T cells, but exactly how and where the T cells become activated in the first place has been a long-standing mystery. Autoimmune uveitis, which accounts for up to 15% of severe visual handicap in the Western world, affects the…
