A team of researchers affiliated with several institutions in Singapore has developed an eyepatch with dissolvable needles for use in treating eye diseases. In their paper published in the journal Nature Communications, the group describes their eyepatch and how well it worked in mice

By combining two imaging modalities-adaptive optics and angiography-investigators at the National Eye Institute (NEI) can see live neurons, epithelial cells, and blood vessels deep in the eye's light-sensing retina.
The most common tests for glaucoma can underestimate the severity of the condition by not detecting the presence of central vision loss, according to a new Columbia University study
Calcified nodules in the retina are associated with progression to late stages of age-related macular degeneration (AMD). Experts from Queen's University Belfast, working in partnership with the University of Alabama of Birmingham and in collaboration with UK material scientists and US clinical ophthalmology practices, made the ground-breaking discovery that the calcified nodules in the retina – the thin layer of tissue that lines the back of the eye – increase the risk for progression to advanced AMD more than six times
A new study shows that an implantable delivery system for a widely used medication to treat a blinding eye disease has enabled some patients to go 15 months in between treatments. This represents a vast improvement over the typical regimen of nearly monthly eye injections
An enzyme is known to help our liver get rid of ammonia also appears to be good at protecting our retina, scientists report. Our retina, which captures light and converts it into neural signals that go to the brain so we can see, can be damaged or destroyed by conditions that reduce blood flow like diabetes, glaucoma or hypertension
Ocular inflammation uveitis is a serious disease that can destroy eye tissue and cause irreversible blindness. Fortunately, blindness and eye damage can be prevented by suppressing the immune system and treating the disease with corticosteroids, said Sai Chavala, MD, Professor of Pharmacology and Neuroscience and Director of Translational Research at the North Texas Eye Research Institute at UNT Health Science Center.
A new form of therapy may halt or even reverse a form of progressive vision loss that, until now, has inevitably led to blindness. This hyper-targeted approach offers hope to individuals living with spinocerebellar ataxia type 7 (SCA7) and validates a new form of therapy with the potential to treat neurogenetic diseases effectively and with far fewer side effects than other medications. Details of this therapy appear in the latest issue of Science Translational Medicine
The standard treatment for a so-called lazy eye (amblyopia) in children is to cover the nonimpaired eye with a patch. This trains the impaired eye to work harder. Such therapy is successful only when the patient wears the eyepatch for the prescribed period of time. This is often not the case, however, as many children feel self-conscious about wearing the patch and reject this form of treatment
Researchers from the University of California, Irvine School of Medicine, have discovered that neurons located in the vision centers of the brains of blind rats functioned normally following fetal retina cell transplants, indicating the successful restoration of vision. The research was published today in JNeurosci, the Journal of Neuroscience
IUPUI biologists are growing 'mini retinas' in the lab from stem cells to mimic the growth of the human retina. The researchers hope to use the research to restore sight when critical connections between the eye and the brain are damaged. These models also allow the researchers to better understand how cells in the retina develop and are organized. These results are published online in Scientific Reports
