Pentosan Polysulfate Sodium (Pps, Elmiron) Maculopathy Demonstrates The Importance Of Coordinated Care From A Low Vision Perspective, Charlotte I. Spada Od, Stephanie Schmiedecke Barbieri Od, Patricia Sanchez Diaz Dvm, Phd, Jeffrey Rabin Od, Phd

Optometric Clinical Practice

Background: Pentosan polysulfate sodium (PPS, Elmiron®) is a widely used medication to reduce pain caused by interstitial cystitis, a bladder disorder most often affecting females. PPS maculopathy is a novel form of toxic retinal disease often not recognized or mistaken for other retinal conditions such as macular degeneration due to the initial similarities on fundus exam. However, when visualized using fundus autofluorescence, affected eyes show characteristic hyper/hypo-autofluorescent patterns.

Case report: A patient taking PPS for 10 years presented with macular changes and complaints of blurry vision and nyctalopia. Clinical, electrodiagnostic, and genetic testing were performed including fundus autofluorescence and …

Retinal organoids represent a promising regenerative strategy for restoring vision in retinal degenerative diseases, but the capacity of host cone bipolar cells in the primate macula to rewire with transplanted photoreceptors has not been established. In this study, we transplanted genome-edited ISL1-/- human retinal organoids lacking ON-bipolar cells into an acute laser-induced macular photoreceptor ablation non-human primate model. Using immunohistochemistry, ultrastructural imaging, and focal macular electroretinography, we demonstrate that host rod and cone bipolar cells actively extend dendrites toward grafted photoreceptors and form synaptic contacts, with evidence of functional signal transmission in a subset of transplanted eyes. Longitudinal, per-eye analyses …

Despite effective lipid-lowering therapies, atherosclerosis continues to be a leading cause of death, with considerable residual cardiovascular risk. Atherosclerotic lesions develop preferentially at arterial regions exposed to disturbed flow (d-flow), which induces genomic stress, endothelial injury, and barrier dysfunction. Hemodynamic forces are known to reprogram endothelial metabolism, but the role of de novo purine synthesis (DNPS), which supplies nucleotides for genome maintenance and whose terminal steps are catalyzed by the bifunctional enzyme ATIC, remains undefined in atherosclerosis. By integrating bulk and single-cell multiomics with in vitro flow systems and in vivo models, we show that d-flow upregulates DNPS and ATIC …

Age-Independent Anti-Angiogenic Therapy For Choroidal Neovascularization By Targeting Secretogranin Iii, Chengchi Huang, Hong Tian, Wei Li

Faculty, Staff and Students Publications

Recent studies reported that anti-angiogenic drugs targeting vascular endothelial growth factor (VEGF) alleviate choroidal neovascularization (CNV) in young but not aged animals. We recently developed a disease-targeted anti-angiogenic therapy against secretogranin III (Scg3), which selectively binds to diseased but not healthy vessels in young mice. Herein, using a unique in vivo ligand binding assay, we predicted and confirmed that Scg3 selectively binds CNV vessels in both young and aged mice. In contrast, VEGF with minimal increased binding to CNV vessels exhibited an age-dependent decline in binding to both CNV and healthy vessels with negligible binding in aged mice. Based on …
