Surgeons perform world’s first operation inside the eye using a robot

Robert MacLaren, Professor of Ophthalmology. assisted by Dr Thomas Edwards, Nuffield Medical Fellow, used the remotely controlled robot to lift a membrane 100th of a millimetre thick from the retina at the back of the right eye of the Revd Dr William Beaver, 70, an Associate Priest at St Mary the Virgin, Iffley, Oxford. He is the first patient ever to undergo this experimental procedure. Read the … [Read more...]

Curing blindness by repairing corneas with invisible films

The University of Melbourne–lead team of researchers have grown corneal cells on a layer of film that can be implanted in the eye to help the cornea heal itself. They have successfully restored vision in animal trials and are aiming to move to human trials next year.  "The hydrogel film we have developed allows us to grow a layer of corneal cells in the laboratory," says Berkay. "Then, we can … [Read more...]

Gene-based agents for the treatment of congenital eye diseases

Pharmacologists at LMU have developed gene-based agents for the treatment of congenital eye diseases. The first of these is now undergoing a phase-I clinical trial in color-blind patients at the University Medical Center in Tübingen. Is this approach translatable in principle to other visual disorders? Michalakis: About 200 genes have been identified which, when mutated, lead to monogenetic … [Read more...]

In February the company won U.S. Food and Drug Administration (FDA) breakthrough status for new multiple sclerosis drug Ocrevus. That was followed in … [Read more...]

Activation of the molecular chaperone, sigma 1 receptor, preserves cone function in a murine model of inherited retinal degeneration.

Retinal degenerative diseases are major causes of untreatable blindness, and novel approaches to treatment are being sought actively. Here we explored the activation of a unique protein, sigma 1 receptor (Sig1R), in the treatment of PRC loss because of its multifaceted role in cellular survival.  We used Pde6βrd10 (rd10) mice, which harbor a mutation in the rod-specific phosphodiesterase gene … [Read more...]

Prismatic eyewear for patients with tunnel vision to launch

A trio of eyeglasses using revolutionary prism techniques could open up a whole new field of view for patients with hemianopia.  The three designs – yoked prisms in a carrier lens, a bi-part double Fresnel prism, and the mirror-based periscopic prisms – were showcased in the journal Optometry and Vision Science.  Lead researcher and Harvard Medical School ophthalmology professor, Dr Eli Peli, told … [Read more...]

Intraocular therapy prevents or reverses diabetic retinopathy in mice

Pathologic changes of the retina caused by diabetes is the leading cause of blindness in working adults. Diabetic retinopathy has no known cure, treatment options are inadequate, and prevention strategies offer limited protection. In the first of its kind, a report in The American Journal of Pathology describes a potential new intraocular treatment based on manipulating the renin angiotensin … [Read more...]
