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).

Vitamin E - The Next 100 Years.

IUBMB Life 2018 Dec 14. Epub 2018 Dec 14.

Vascular Biology Laboratory, JM USDA-HNRCA at Tufts University, Boston, Massachusetts.

α-Tocopherol is the only tocopherol that has been shown to prevent the human deficiency disease Ataxia with Isolated Vitamin E Deficiency (AVED), and thus it is the only one that, for humans, can be called vitamin E. Vitamin E in addition to preventing AVED has documented immune boosting properties and an activity against nonalcoholic hepatosteatosis and low-grade inflammation. Epidemiological studies indicating that vitamin E could prevent cardiovascular events, neurodegenerative disease, macular degeneration, and cancer were in general not confirmed by clinical intervention studies.

Interferon-α-induced retinopathy in chronic hepatitis C treatment: summary, considerations, and recommendations.

Graefes Arch Clin Exp Ophthalmol 2018 Dec 13. Epub 2018 Dec 13.

Department of Ophthalmology and Vision Sciences, Princess Margaret Hospital/University Health Network, University of Toronto, 610 University Avenue, Toronto, ON, M5G 2M9, Canada.

Interferons are cytokines that regulate the host's response to viral infection, particularly in the setting of the immunologic response to the hepatitis C virus (HCV). While the virus has the ability to evade the host's innate and specific immunity, exogenous interferon-α with combined ribavirin, treatments have been found to achieve a significant sustained viral response in subgroups of patients with chronic HCV. One of the major side effects of interferon-α is an ocular retinopathy characterized by flame-shaped hemorrhages and cotton wool spots visualized on funduscopic examination. Read More

Torsten Bohn

Int J Vitam Nutr Res 2018 Dec 14:1-10. Epub 2018 Dec 14.

Carotenoids are C-30, C-40 or C-50 terpenoids produced by a number of bacteria, fungi, and plants. In addition to acting as vitamin A precursors such as β-carotene, their dietary intake and blood plasma/serum and tissue levels have been associated in several epidemiological studies to the reduced incidence of chronic diseases, including the reduction of type 2 diabetes and other cardiometabolic diseases, as well as some types of cancer. Lutein and zeaxanthin also appear to play a role in the amelioration of age-related macular degeneration (AMD), the main cause of blindness in the elderly, and may be regarded as conditionally essential nutrients for the elderly.

Progress in optical coherent tomography (OCT) has recently provided new insights into variety of chorioretinal disorders. The use of EDI (Enhanced Depth Imaging) during OCT examinations and as well as OCT angiography provides a more accurate analysis of the choroid both quantitatively and qualitatively. "Pachychoroid" (greek pachy- [παχύ] - thick) is defined as an abnormal and sustained increase in choroidal thickness 300 μm, which is mainly due to dilated choroidal vessels in the Hallers layer and other structural changes in physiological choroidal architecture.

Objective: Intraocular lens (IOL) repositioning using a closed-eye approach could be carried out in some selected cases. Our study focuses on the efficacy and safety of a IOL closed-eye repositioning technique using scleral suture, which is performed using a trocar as an intrastromal limbal guide.

Methods And Analysis: Thirty-one eyes of 31 patients with late IOL dislocation operated on between January 2015 and May 2017 were included in this retrospective non-comparative consecutive case series study. Read More

Ability of Swept-Source Optical Coherence Tomography to Detect Retinal and Choroidal Changes in Patients with Multiple Sclerosis.

J Ophthalmol 2018 13;2018:7361212. Epub 2018 Nov 13.

Ophthalmology Department, Miguel Servet University Hospital, Zaragoza, Spain.

Purpose: To evaluate the ability of new swept-source (SS) optical coherence tomography (OCT) technology to detect changes in retinal and choroidal thickness in patients with multiple sclerosis (MS).

Methods: A total of 101 healthy and 97 MS eyes underwent retinal and choroidal assessment using SS Triton OCT (Topcon). Macular thickness and peripapillary data (retinal, ganglion cell layer (GCL+, GCL++) and retinal nerve fiber layer (RNFL) thickness) were analyzed, including choroidal thickness evaluation.

Safety of high-dose intravitreal triamcinolone acetonide as low-cost alternative to anti-vascular endothelial growth factor agents in lower-middle-income countries.

Clin Ophthalmol 2018 26;12:2383-2391. Epub 2018 Nov 26.

Department of Ophthalmology, Faculty of Medicine, Benha University, Benha, Egypt.

Purpose: The purpose of this study was to evaluate the safety of high-dose intravitreal triamcinolone acetonide (IVTA) as affordable low-cost alternative to anti-vascular endothelial growth factor (anti-vascular endothelial growth factor [anti-VEGF] agents) in lower-middle-income countries.

Patients And Methods: This was a retrospective interventional non-comparative case series. The study recruited patients who received 20 mg IVTA for treating various retinal and optic nerve diseases over the past 5 years. Read More

Posterior staphyloma in pathologic myopia.

Prog Retin Eye Res 2018 Dec 8. Epub 2018 Dec 8.

Department of Ophthalmology, Medical Faculty Mannheim, Ruprecht-Karls-University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Germany. Electronic address:

A posterior staphyloma is an outpouching of a circumscribed region of the posterior fundus and has been considered a hallmark of pathologic myopia. Occurring in highly myopic eyes, it is histologically characterized by a relatively abrupt scleral thinning starting at the staphyloma edge, a pronounced de-arrangement of scleral collagen fibrils and a marked choroidal thinning, which is the most marked at the staphyloma edge and which occurs in addition to the axial elongation-associated choroidal thinning. Besides in highly myopic eyes, a posterior staphyloma can be found in non-highly myopic eyes in association with retinitis pigmentosa or localized defects of Bruch's membrane in the cases of which it is not associated with a marked choroidal thinning.
