Connexin43 hemichannel block protects against the development of diabetic retinopathy signs in a mouse model of the disease.

J Mol Med (Berl) 2018 Dec 8. Epub 2018 Dec 8.

Buchanan Ocular Therapeutics Unit, Department of Ophthalmology and the New Zealand National Eye Centre, University of Auckland, Auckland, New Zealand.

Diabetic retinopathy (DR) is a vascular disease of the neuroretina characterised by hyperglycaemia and inflammation. Current DR therapies target late-stage vascular defects and there is evidence to suggest that they contribute to geographic atrophy and retinal ganglion cell death long term. Therefore, alternative treatments that target common upstream disease mechanisms are needed. Read More

Int J Retina Vitreous 2018 30;4:45. Epub 2018 Nov 30.

Gavin Herbert Eye Institute, University of California Irvine, 850 Health Sciences Road, Irvine, CA 92697 USA.

Background: Prader-Willi syndrome (PWS) is a genetic disease caused by loss of expression of the paternally inherited copy of several genes on the long arm of chromosome 15. Ophthalmic manifestations of PWS include strabismus, amblyopia, nystagmus, hypopigmentation of the iris and choroid, diabetic retinopathy, cataract and congenital ectropion uvea. An overlap between PWS and oculocutaneous albinism (OCA) has long been recognized and attributed to deletion of OCA2 gene located in PWS critical region (PWCR). Read More

Antifouling Super Water Absorbent Supramolecular Polymer Hydrogel as an Artificial Vitreous Body.

Adv Sci (Weinh) 2018 Nov 25;5(11):1800711. Epub 2018 Sep 25.

School of Materials Science and Engineering Tianjin Key Laboratory of Composite and Functional Materials Tianjin University Tianjin 300350 China.

Recently, there has been a high expectation that high water absorbent hydrogels can be developed as an artificial vitreous body. However, the drawbacks associated with in vivo instability, biofouling, uncontrollable in situ reaction time, and injection-induced precrosslinked fragmentation preclude their genuine use as vitreous substitutes. Here, a supramolecular binary copolymer hydrogel termed as PNAGA-PCBAA by copolymerization of -acryloyl glycinamide (NAGA) and carboxybetaine acrylamide (CBAA) is prepared. Read More

Systemic Approach to Prevent Inadvertent Perfusion in Eyes with Extensive Choroidal Detachment, Suprachoroidal Fluid, and Hypotony During Pars Plana Vitrectomy.

Adv Ther 2018 Nov 24. Epub 2018 Nov 24.

State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center of Sun Yat-sen University, Guangzhou, China.

Introduction: Rhegmatogenous retinal detachment (RRD) with extensive choroidal detachment (CD), suprachoroidal fluid (SCF), and lower intraocular pressure (IOP) markedly increase the difficulty of pars plana vitrectomy (PPV) because it makes the insertion and placement of the trocar cannulas for PPV time-consuming and technically challenging. In this study, we developed a systemic approach that avoids the risks of sclerotomy or using a longer trocar to help in the safe placement of the trocar cannulas in order to prevent inadvertent fluid/air perfusion during PPV in RRD eyes with extensive CD, SCF, and hypotony.

Methods: This is a prospective case series study. Read More

Ocular kinetics and safety of intravitreally injected angiotensin converting enzyme inhibitor lisinopril.

Int J Retina Vitreous 2018 14;4:42. Epub 2018 Nov 14.

2Ocular Pharmacology and Pharmacy Division, Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, 110029 India.

Background And Objectives: The study investigated the intravitreal safety and vitreous disposition of lisinopril, an angiotensin converting enzyme inhibitor in rabbits for its projected use in retinopathy.

Methods: For the safety study, following the baseline ERG recording and fundus photography, 40 µg/50 µl of lisinopril sterile injection was injected unilaterally in the rabbit eyes (n = 4), where other eye served as a control. The electroretinogram and fundus images were obtained at 24, 48, 72 and 168 h following the intravitreal injection. Read More

Prion Seeds Distribute throughout the Eyes of Sporadic Creutzfeldt-Jakob Disease Patients.

MBio 2018 Nov 20;9(6). Epub 2018 Nov 20.

Department of Pathology, University of California, San Diego, La Jolla, California, USA

Sporadic Creutzfeldt-Jakob disease (sCJD) is the most common prion disease in humans and has been iatrogenically transmitted through corneal graft transplantation. Approximately 40% of sCJD patients develop visual or oculomotor symptoms and may seek ophthalmological consultation. Here we used the highly sensitive real-time quaking-induced conversion (RT-QuIC) assay to measure postmortem prion seeding activities in cornea, lens, ocular fluid, retina, choroid, sclera, optic nerve, and extraocular muscle in the largest series of sCJD patient eyes studied by any assay to date.

Targeting Interleukin-23 in the Treatment of Noninfectious Uveitis.

Ophthalmology 2018 Dec 4;125(12):1977-1983. Epub 2018 Jul 4.

Casey Eye Institute, Oregon Health & Science University, Retinal and Vitreous Diseases/Surgery, Ocular Inflammation and Immunology, Portland, Oregon.

The interleukin (IL)-23/IL-17 axis plays a central role in the pathogenesis of immune-mediated diseases such as psoriasis, psoriatic arthritis, Crohn's disease, and uveitis. Therefore, targeting the IL-23/IL-17 axis has become the focus of multiple clinical trials for drug development in patients with autoimmune diseases. We briefly describe the biology of the IL-23/IL-17 axis and its relevance to the pathogenesis of experimental and clinical uveitis, and review the monoclonal antibody therapies targeting this pathway.

Iatrogenic Posterior Lens Capsule Rupture and Subsequent Complications due to Nd:YAG Laser Vitreolysis for Vitreous Floaters: A Case Report.

Ophthalmic Surg Lasers Imaging Retina 2018 Nov;49(11):e214-e217

Nd:YAG laser vitreolysis has been used as a noninvasive approach to treat visually significant vitreous strands and floaters. However, severe vision-threatening complications may occur. The authors describe a rare case of a 60-year-old woman who had suffered rupture of the posterior lens capsule with subsequent cataract formation 1 week post-Nd:YAG laser vitreolysis in the right eye.

Surgical Management of an Externally Protruding, Perforating Intraocular Foreign Body.

Ophthalmic Surg Lasers Imaging Retina 2018 11;49(11):904-906

Ru-ik Chee Felix Y. Chau In this case of a perforating eye injury by a 2-inch-long nail that went through the cornea, lens, and posterior eye wall, the authors describe a combined external, anterior, and posterior segment surgical approach that resulted in safe and successful removal of the foreign body. Initial external trimming of the protruding nail facilitated the use of a noncontact viewing system. Read More

Bilateral Vitreous Hemorrhage Following Bilateral Intravitreal Injections of Bevacizumab in an Infant With Retinopathy of Prematurity.

Ophthalmic Surg Lasers Imaging Retina 2018 Nov;49(11):893-896

Since the publication of BEAT-ROP in 2011, intravitreal bevacizumab (IVB) has become increasingly common for the treatment of posterior type 1 retinopathy of prematurity (ROP). However, long-term data on the safety and efficacy of IVB for ROP are lacking. Vitreous hemorrhage following bevacizumab injections have been rarely reported in infants with ROP, and the need for treatment of these hemorrhages remains in question. Read More

Toxicity and in vivo release profile of sirolimus from implants into the vitreous of rabbits' eyes.

Doc Ophthalmol 2018 Nov 19. Epub 2018 Nov 19.

Faculty of Pharmacy, Federal University of Minas Gerais, Belo Horizonte, CEP 31270-901, Brazil.

Purpose: To assess the in vivo release profile and the retinal toxicity of a poly (lactic-co-glycolic acid) (PLGA) sustained-release sirolimus (SRL) intravitreal implant in normal rabbit eyes.

Methods: PLGA intravitreal implants containing or not SRL were prepared, and the viability of ARPE-19 and hES-RPE human retinal cell lines was examined after 24 and 72 h of exposure to implants. New Zealand rabbits were randomly divided into two groups that received intravitreal implants containing or not SRL. Read More
