IU Research Points Toward New Blindness Prevention Methods in Diabetic Eye Disease

VEGF_Oxygen_charts_1x1.jpg

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.

Alzheimer’s Detected Before Symptoms via New Eye Technology

Scientists may have overcome a major roadblock in the development of Alzheimer’s therapies by creating a new technology to observe ― in the back of the eye ― progression of the disease before the onset of symptoms. Clinical trials are to start in July to test the technology in humans according to a paper recently published in Investigative Ophthalmology & Visual Science ( IOVS).

Use It or Lose It: Visual Activity Regenerates Neural Connections Between Eye and Brain

axonsmagentaandgreenregeneratingintheadultbrain.jpg

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.

Routine Eye Exams Lead to High Rate of Change in Vision Status or Care

Do you really need to get your eyes checked—even if you haven't noticed any vision problems or eye-related symptoms? More than half of routine eye examinations in asymptomatic patients lead to a change in vision prescription or other changes in care, according to a study in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

Current Stimulation of the Brain Restores Vision in Patients with Glaucoma and Optic Nerve Damage

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.

Wechselstrom-Stimulation Des Gehirns Verbessert Sehleistung Bei Patienten Mit Glaukom Und Sehnervschädigung

Der Verlust der Sehkraft durch Glaukom oder Schädigung des Sehnervs gilt als irreversibel. 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.

Lizard Tail Adaptations May Reflect Predators' Color Vision Capabilities

118225_web.jpg

Juveniles of numerous lizard species have a vividly blue-colored tail that likely serves to deflect predator attacks toward the detachable tail rather than the lizard's body. Now researchers have found that certain differences in blue and UV light reflectance in lizard tails are likely adaptations to predators with different color vision capabilities.

About 9.6 million U.S. adults are severely nearsighted, a new study shows. Researchers also found that 41,000 suffer a rare complication that can cause blindness, with the prevalence rate among women double that of men. Published in Ophthalmology, the journal of the American Academy of Ophthalmology.
