Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear have identified new underlying mechanisms of proptosis, or bulging of the eyes, in patients with acute thyroid eye disease. In a report published online in the journal Ophthalmology, the researchers describe vascular growth factors causing an abnormal proliferation of blood vessels, as well as the rare formation of lymphatic vessels, that may contribute to the dangerous swelling and inflammation that occurs in the orbits of these patients. The findings point to new potential targets for non-surgical therapies to decompress the eye in the acute phase of thyroid eye disease.

San Francisco, CA, August 16, 2016 - Because of the beneficial effect of corticosteroids on lung function, especially in infants who are ventilator dependent, corticosteroids are, at times, administered to very low birth weight neonates to treat established or evolving lung disease. However, it has long been suspected that steroids may have negative neurodevelopmental effects on very premature infants. In a study in the Journal of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS), researchers found that for very premature infants with birth weights of less than 500 grams, there was a 1.6 times increased risk for retinopathy of prematurity (ROP) and a 1.7 times greater chance for advanced ROP.

Indiana University researchers have created a virtual tissue model of diabetes in the eye that shows precisely how a small protein that can both damage or grow blood vessels in the eye causes vision loss and blindness in people with diabetes. The study, reported in the journal PLOS Computational Biology, could also lead to better treatment for diabetic retinopathy, which currently requires multiple, invasive procedures that aren’t always effective in the long term.

A study in mice funded by the National Institutes of Health (NIH) shows for the first time that high-contrast visual stimulation can help damaged retinal neurons regrow optic nerve fibers, otherwise known as retinal ganglion cell axons. In combination with chemically induced neural stimulation, axons grew further than in strategies tried previously. Treated mice partially regained visual function. The study also demonstrates that adult regenerated central nervous system (CNS) axons are capable of navigating to correct targets in the brain. The research was funded through the National Eye Institute (NEI), a part of NIH.

Vision loss due to glaucoma or optic nerve damage is generally considered irreversible. Now a new prospective, randomized, multi-center clinical trial demonstrates significant vision improvement in partially blind patients after 10 days of noninvasive, transorbital alternating current stimulation (ACS). In addition to activation of their residual vision, patients also experienced improvement in vision-related quality of life such as acuity, reading, mobility or orientation. The results are reported in PLOS ONE.

Jetzt zeigt eine prospektive, randomisierte, multizentrische, klinische Studie signifikante Verbesserungen des Sehvermögens in teilweise erblindeten Patienten nach 10 Tagen Behandlung mit nicht-invasiver, transorbitaler Wechselstromstimulation (alternating current stimulation, ACS). Die Behandlung führte zu der Aktivierung von Restsehleistungen und sehbezogenen Verbesserungen der Lebensqualität wie Sehschärfe, Lesen, Mobilität und Orientierung. Diese aktuellen Ergebnisse wurden in PLOS ONE berichtet.

Knowing the exact number of molecules located at specific junctures in cells can be a critical measure of health as well as disease. For example, abnormally high numbers of growth factor receptors on cells can be an indication of cancerous and precancerous states. Now, a simplified method known as qPAINT uses the blinking pattern of the light that marks each molecule, to find, count, and study individual molecules that are just a few nanometers apart.

When Aleksandra Pryszczewska was a toddler, she often stumbled and bumped into things because of an eye condition called strabismus, or lazy eye. Her left eye veered to the far right, altering her line of vision causing her sight to be impaired. While strabismus is traditionally corrected during early childhood, Ms. Pryszczewska's only surgery was unsuccessful. Loyola is one of the few medical centers that treats adult strabismus.
