Emory Eye Center Implants Its First Retinal Chips In Patients With Retinitis Pigmentosa

An expanded clinical trial conducted by Optobionics Corporation involving the implantation of a retina mircrochip has allowed Emory Eye Center and the Atlanta Veterans Affairs Rehabilitation Research & Development Center to implant the device in several patients. The patients all have retinitis pigmentosa with moderate-to-severe vision loss. Three centers in the United States have been chosen...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss

Ophthalmologists at Rush University Medical Center implanted Artificial Silicon Retina (ASR) microchips in the eyes of five patients to treat vision loss caused by retinitis pigmentosa (RP). The implant is a silicon microchip 2mm in diameter and one-thousandth of an inch thick, less than the thickness of a human hair. Four patients had surgery Tuesday, January 25. The fifth patient is sch...

Six previously blind patients detect light, motion, identify objects with retinal prostheses

Researchers from the University of Southern California and the Doheny Eye Institute's Doheny Retina Institute will be presenting data on the first six patients implanted with an intraocular retinal prosthesis-more popularly referred to as an artificial retina-developed and manufactured in partnership with Second Sight Medical Products, Inc., of Sylmar, Calif. According to Mark Humayun, pro...

Retina adapts to seek the unexpected, ignore the commonplace

Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace. The scientists report in this week's issue of the journal Nature on their finding that this principle of novelty-detection operates in many visual environments. "Appar...

The Clue to a Diabetic Requiring an Amputation may lie in the Retina of ones Eye.

Amputations continue to be a major complication of diabetes, despite the fact most are preventable. About one //half of all amputations are currently performed among the diabetic population. Researchers studied changes in the tiny blood vessels in the retinas of about 900 diabetic patients who had been diagnosed with the disease before age 30. All were followed for 20 years to assess ho...

Retinal Hemorrhage: No More a Sure Sign of Child Abuse

A new study has now found out that retinal examination of a child, to determine the location and number of hemorrhages may not be a sure sign of abuse. // This was discussed in the American Academy of Forensic Sciences annual meeting held in Seattle recently. Retina is a light sensitive tissue located behind the eye. Any rupture in the retinal surface can damage the tiny blood vessels a...

Another feather in fish oil cap: hope against retinal degenerative diseases

Fish oil has numerous health benefits and is being touted as a new age elixir. So another research is in its honour is welcome.Nicolas G. Bazan, MD, PhD, Boyd Professor// and Director of the Neuroscience Centre of Excellence at LSU Health Sciences Centre in New Orleans, in a paper reports on the role that the omega-3 fatty acids in fish oil play in protecting cells in the retina from degenerativ...

There is light at the end of the blind tunnel: prosthetic retinal cells offer hope!

People with inherited retinal degeneration have hope of vision since researchers have engineered cells in the eye to be light sensitive that were not before.// Zhuo-Hua Pan of Wayne State University School of Medicine and colleagues have engineered this technology using a harmless virus, they introduced a gene for a light-sensitive protein into "inner retinal neurons" in a strain of mic...
