Age-related macular degeneration (AMD), the leading cause of vision loss among older adults in the United States, is often associated with psychological stress. A simple stress rating scale (the Perceived Stress Scale) is a valid and useful way to evaluate the connection between stress and progressive vision loss from AMD, according to a study in the March issue of Optometry and Vision Science, the official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

It is no secret that the issues associated with current glaucoma medications can be problematic. Systemic medications carry the risk of side effects, while the current medical treatment of choice, eye drops, has its own drawbacks. Studies show that half of patients stop taking their prescription glaucoma eye drops after a year, leaving them vulnerable to vision loss

A study published in Obstetrics and Gynecology suggests that pre-eclampsia may be associated with retinal disease in the mother later in life. Pre-eclampsia is a pregnancy complication characterized by high blood pressure and large amounts of protein in the urine. According to this study, more severe and earlier-onset pre-eclampsia was associated with even higher risk.

Symptoms of dry eye syndrome -- dry, red, itchy, gritty, sore eyes -- are more common among contact lens wearers. But relief may be on the horizon, thanks to a group of Stanford University researchers and their work exploring the mechanical interactions between the eye surface, the cornea and contact lenses. Ultimately, the group’s goal is to create better contact lenses that maximize comfort and alleviate dry eye symptoms, and their work will be presented at the Society of Rheology meeting being held Feb. 12-16, in Tampa, Florida.

Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear have shown that a slight increase in transforming growth factor beta (TGF-β), which is present in preclinical animal models with diabetic eye disease, protects retinal blood vessels from damage that commonly occurs in the early stages of the disease (known as diabetic retinopathy). Their findings, published in the American Journal of Pathology, may lead to targeted therapeutics that delay or prevent the development of the disease in patients.

Researchers from Schepens Eye Research Institute of Massachusetts Eye and Ear have uncovered two factors responsible for the chronic, lifelong nature of autoimmune disorders, which tend to “flare up” intermittently in affected patients. These two factors are cell-signaling proteins called cytokines—specifically Interleukin-7 and -15 (IL-7 and IL-15)—that are secreted by cells of the immune system and help modulate memory Th17 cells, a subset of T cells which are known to contribute to autoimmune disorders. Until now, it was unclear how Th17 cells maintained memory; the study results show that IL-7 and IL-15 signal the Th17 cells to chronically reside in the body.
