Immune cells in the retina and choroid: Two different tissue environments that require different defenses and surveillance.

Prog Retin Eye Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Anatomy and Developmental Biology, Monash Biomedicine Discovery Institute, Monash University, Clayton, Victoria, Australia.

In the eye immune defenses must take place in a plethora of differing microenvironments ranging from the corneal and conjunctival epithelia facing the external environment to the pigmented connective tissue of the uveal tract containing smooth muscle, blood vessels and peripheral nerves to the innermost and highly protected neural retina. The extravascular environment of the neural retina, like the brain parenchyma, is stringently controlled to maintain conditions required for neural transmission. The unique physiological nature of the neural retina can be attributed to the blood retinal barriers (BRB) of the retinal vasculature and the retinal pigment epithelium, which both tightly regulate the transport of small molecules and restrict passage of cells and macromolecules from the circulation into the retina in a similar fashion to the blood brain barrier (BBB).

Lymphatic Vascular Structures: A New Aspect in Proliferative Diabetic Retinopathy.

Int J Mol Sci 2018 Dec 13;19(12). Epub 2018 Dec 13.

Research Programs Unit, Genome-Scale Biology, Biomedicum Helsinki, University of Helsinki, FI-00014 Helsinki, Finland.

Diabetic retinopathy (DR) is the most common diabetic microvascular complication and major cause of blindness in working-age adults. According to the level of microvascular degeneration and ischemic damage, DR is classified into non-proliferative DR (NPDR), and end-stage, proliferative DR (PDR). Despite advances in the disease etiology and pathogenesis, molecular understanding of end-stage PDR, characterized by ischemia- and inflammation-associated neovascularization and fibrosis, remains incomplete due to the limited availability of ideal clinical samples and experimental research models.

Asymmetric Expression of LincGET Biases Cell Fate in Two-Cell Mouse Embryos.

Cell 2018 Dec;175(7):1887-1901.e18

State Key Laboratory of Stem Cell and Reproductive Biology, Institute of Zoology, Chinese Academy of Sciences, 100101 Beijing, China; University of Chinese Academy of Sciences, 100049 Beijing, China; Institute for Stem Cell and Regeneration, Chinese Academy of Sciences, 100101 Beijing, China. Electronic address:

In early mammalian embryos, it remains unclear how the first cell fate bias is initially triggered and amplified toward cell fate segregation. Here, we report that a long noncoding RNA, LincGET, is transiently and asymmetrically expressed in the nucleus of two- to four-cell mouse embryos. Overexpression of LincGET in one of the two-cell blastomeres biases its progeny predominantly toward the inner cell mass (ICM) fate. Read More

Vernal Keratoconjunctivitis.

Surv Ophthalmol 2018 Dec 11. Epub 2018 Dec 11.

Department of Ophthalmology, Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.

Vernal keratoconjunctivitis, a chronic, bilateral, seasonal allergic inflammatory disease of the eye, is an important cause of visual debilitation and impairment of quality of life in children and young adults in certain parts of the world such as the Mediterranean areas, Central and West Africa, the Middle East, Japan, the Indian subcontinent, and South America. It usually has a self-limiting course; however, in a few cases the disease is recurrent and leads to long-term visual disabling complications like keratoconus and limbal stem cell deficiency. The main pathogenic mechanism is IgE mediated; however, there may be non-IgE and certain non-specific hypersensitivity mechanisms. Read More

Department of Clinical Epidemiology and Biostatistics, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Purpose: To investigate whether the relationship between circumpapillary vascular density (cpVD) and visual field (VF) mean sensitivity (MS) differs between primary open-angle (POAG) and angle-closure glaucoma (PACG).

Reconstruction of the orbital rim and floor following tumor excision is traditionally performed with bone grafts, vascularized grafts, or free flaps. The authors describe a case of an osteosarcoma of the maxillary sinus and a second case of an ossifying fibroma of the orbital floor, both of which required reconstruction of the orbital floor and rim. In both of these cases, reconstruction of the orbital floor and rim was performed with a titanium implant whose anterior portion was bent inferiorly to recreate the orbital rim. Read More

Ocular Considerations in Face Transplantation: Report of 2 Cases and Review of the Literature.

Ophthalmic Plast Reconstr Surg 2018 Dec 7. Epub 2018 Dec 7.

The Hansjörg Wyss Department of Plastic Surgery and.

Purpose: Periorbital injuries are common in face transplantation (FT) candidates. It is therefore essential that the ophthalmologist play a central role in the multidisciplinary treatment of these patients. In this study, the authors perform a comprehensive review of all procedures involving periorbital components, provide an update for the ophthalmology community regarding the current state of the field, and present 2 cases.

A Rare Cause for Recurrent Implant-Related Inflammation of Orbit: Dacryocystitis.

J Craniofac Surg 2018 Dec 13. Epub 2018 Dec 13.

Plastic, Reconstructive, and Aesthetic Surgery Department of Mersin University Medical Faculty, Mersin, Turkey.

Ultra-thin porous polyethylene has been widely preferred in orbital blow out fracture repair for many years as a safe and stable material. Delayed complications related to the implant in orbital blow out fracture repair are very rare and usually begin as a periorbital inflammation. Infections and tissue reaction to the foreign body are regarded as main causes for implant-related inflammation of which symptoms may vary among the patients and may involve subacute and chronic eyelid swelling, skin redness, pain, conjunctival injection, proptosis, and acute orbital inflammation.

Fourier Analysis of Corneal Irregular Astigmatism Due to the Anterior Corneal Surface in Dry Eye.

Eye Contact Lens 2018 Dec 11. Epub 2018 Dec 11.

Departments of Innovative Visual Science (S.K., K.M.), and Ophthalmology (S.K., N.M., M.O., S.A., Y.T., K.M., K.N.), Osaka University Graduate School of Medicine, Osaka, Japan; Research and Development Division (Y.T.), Rohto, Kyoto, Japan; and Department of Ophthalmology, Icahn School of Medicine at Mount Sinai (S.D.K.), New York, NY.

Objectives: To evaluate corneal irregular astigmatism due to the anterior corneal surface using Fourier harmonic analysis with a Placido ring-based corneal topographer (Placido-based topographer) and three-dimensional anterior segment optical coherence tomography (OCT) in dry eyes.

Methods: Forty-four eyes of 44 subjects with dry eye and 20 eyes of 20 normal control subjects were enrolled. Corneal topographic data were obtained using a Placido-based topographer and OCT. Read More

e Market Access, Health Economics and Outcomes Research , Bayer Yakuhin, Ltd , Tokyo , Japan.

Aims: To estimate the impact of anti-vascular endothelial growth factor (VEGF) agents on visual impairment and blindness avoided in patients with diabetic macular edema (DME) and on associated patient and caregiver productivity loss in Japan.

Methods: We compared the impact of current care (estimated at 53.8% utilization of anti-VEGF agents using current data) with that of hypothetical care (characterized by a higher utilization of anti-VEGF agents [80. Read More

Department of Ophthalmology, Guangxi Zhuang Autonomous Region People's Hospital.

To analyze the clinical characteristics of ocular tilt reaction in vestibular neuritis patients and discuss its value to the diagnosis of vestibular neuritis.Thirty-five patients with vestibular neuritis confirmed between January 2016 and March 2018 underwent bedside vestibular function physical examination including nystagmus, head impulse test(HIT),head shaking nystagmus(HSN), ocular tilt reaction(OTR), Romberg sign, Fukuda stepping. All patients underwent head CT scan and brain MRI scan + DWI to exclude bleeding and infarction. Read More
