J Ocul Pharmacol Ther 2019 Jan/Feb;35(1):23-31

1 Research Divison, Harry S. Truman Memorial Veterans' Hospital, Columbia, Missouri.

Purpose: This study investigated the efficiency and potential toxicity of a linear 22-kDa polyethylenimine (PEI)-DNA nanoconstruct for delivering genes to corneal cells and the effects of PEI nitrogen-to-DNA phosphate (N:P) ratio on gene transfer efficiency in vitro and in vivo.

Methods: A gel retardation assay, zeta potential measurement, bright-field microscopy, transfection with green fluorescent protein (GFP), immunofluorescence, and enzyme-linked immunosorbent assay (ELISA) were used to characterize the physicochemical and biological properties and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), lactate dehydrogenase (LDH), and reactive oxygen species (ROS) assay for cytotoxicity of the linear PEI-DNA nanoconstruct using in vitro cultured primary human corneal fibroblast and in vivo mouse models.

Results: Of the several evaluated N:P ratios, the highest gene transfection efficiency achieved without any notable cytotoxicity was observed at an N:P ratio of 30:1 (N:P 30). Read More

Gene Therapy for Inherited Retinal Degeneration.

J Ocul Pharmacol Ther 2019 Jan 28. Epub 2019 Jan 28.

Department of Ophthalmology, USC Roski Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles, California.

Inherited retinal degeneration (IRD), a group of rare retinal diseases that primarily lead to the progressive loss of retinal photoreceptor cells, can be inherited in all modes of inheritance: autosomal dominant (AD), autosomal recessive (AR), X-linked (XL), and mitochondrial. Based on the pattern of inheritance of the dystrophy, retinal gene therapy has 2 main strategies. AR, XL, and AD IRDs with haploinsufficiency can be treated by inserting a functional copy of the gene using either viral or nonviral vectors (gene augmentation). Read More

Challenges in the Polyene- and Azole-Based Pharmacotherapy of Ocular Fungal Infections.

J Ocul Pharmacol Ther 2019 Jan/Feb;35(1):6-22. Epub 2018 Nov 8.

1 Department of Pharmaceutics and Drug Delivery, School of Pharmacy, University of Mississippi, Oxford, Mississippi.

Polyenes and azoles constitute 2 major drug classes in the antifungal armamentarium used to treat fungal infections of the eye such as fungal keratitis, endophthalmitis, conjunctivitis, and blepharitis. These classes of drugs have come to occupy an important niche in ophthalmic antifungal therapy due to their broad spectrum of activity against a variety of filamentous and yeast-like fungi. Natamycin suspension (Natacyn), a polyene antifungal drug, is currently the only US FDA-approved formulation for treating ophthalmic fungal infections, whereas the other polyene and azole antifungals such as amphotericin B, fluconazole, itraconazole, ketoconazole, miconazole, voriconazole, and posaconazole are routinely used off-label in the clinical setting.

J Ocul Pharmacol Ther 2018 Oct 12. Epub 2018 Oct 12.

1 Department of Ophthalmology and Visual Sciences, Carver College of Medicine, University of Iowa , Iowa City, Iowa.

Purpose: To determine how the Rho kinase inhibitor, ripasudil, affects metabolic function and cell viability in donor human corneal endothelial cells (HCECs).

Methods: Endothelial cell-Descemet membrane (EDM) tissues were treated with 10 μM ripasudil and assayed for mitochondrial and glycolytic activity using extracellular flux analysis and then compared to untreated controls. In addition, EDM tissues with a 24-h ripasudil treatment and control tissues were exposed to 1 μM staurosporine to induce apoptosis and then analyzed for cell viability using apoptosis and necrosis assays.

Safety and Tolerability of Overdosed Artificial Tears by Abraded Rabbit Corneas.

J Ocul Pharmacol Ther 2018 Oct 12. Epub 2018 Oct 12.

1 SANTEN SAS, Novagali Innovation Center , Evry Cedex, France .

Purpose: Preservative-free cationic emulsion-based artificial tear (AT) is an innovative eye drop based on the Novasorb technology with cetalkonium chloride (CKC) as the cationic agent. The cationic emulsion Cationorm is designed for the management of mild-to-moderate dry eye disease (DED) patients that present cornea epithelium alterations. The aim of the present study was to evaluate the safety and tolerability of overdosed ATs by altered corneal epithelium in vivo and assess the usefulness of the ex vivo eye irritation test (EVEIT) as a predictive alternate toxicity test method.

Topical Cyclosporine Pretreatment of Ocular Surface in Allogeneic Hematopoietic Stem Cell Transplant Recipients.

J Ocul Pharmacol Ther 2018 Nov 5;34(9):628-632. Epub 2018 Oct 5.

2 Department of Ophthalmology, College of Medicine, Yeouido St. Mary's Hospital, The Catholic University of Korea , Seoul, Korea.

Purpose: Dry eye disease (DED) of ocular graft-versus-host disease (GVHD) is a common complication after allogeneic hematopoietic stem cell transplantation (HSCT). Ongoing inflammation and irreversible fibrotic changes of the ocular surface and adnexa are obstacles for effective treatment of ocular GVHD. We hypothesized that topical cyclosporine A (CsA) pretreatment might be effective in preventing ocular GVHD. Read More

Amount of Mononuclear Phagocyte Infiltrate Does Not Predict Area of Experimental Choroidal Neovascularization (CNV).

J Ocul Pharmacol Ther 2018 Sep;34(7):489-499

Department of Ophthalmology, Novartis Institutes for Biomedical Research , Cambridge, Massachusetts.

Purpose: Mononuclear phagocytes (MNPs) are present in neovascular age-related macular degeneration (nv AMD) which is also called choroidal neovascularization (CNV). The number and phenotype of the MNPs depend upon the local environment in the CNV and effect of nv AMD therapy. We investigated ocular cell infiltration and conditions that modulate angiogenesis in a laser-induced mouse CNV model. Read More
