New hope for regenerating the human retina damaged by disease or injuryScientists at Schepens Eye Research Institute have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells, a stem-like cell that can generate new retinal cells. The discovery, published in the March issue of Investigative Ophthalmology and Visual Science (IOVS), offers new hope to victims of diseases that harm the retina, such as macular...

Copernicus Therapeutics, Inc. announced today that a research team at University of Oklahoma Health Sciences Center, led by Dr. Muna Naash, Professor of Cell Biology, demonstrated that Copernicus' DNA nanoparticles corrected vision defects in a mouse model of retinitis pigmentosa (RP). These findings were presented at the American Society of Gene Therapy meeting in Seattle, WA. Mutations in genes important in the biology of vision cause RP, a common genetic form of visual impairment...

Optobionics Corporation, a developer of innovative medical devices for the treatment of vision loss due to degenerative retinal diseases, today provided an update on the interim results from its multi-center, pilot clinical study of the Artificial Silicon Retina (ASR®) device. Results from the 20 patients treated with the ASR device show measurable vision improvement in a significant number of Retinitis Pigmentosa patients. These patients currently have no treatment...

GAINESVILLE, Fla. - University of Florida scientists used a healthy human gene to prevent blindness in mice with a form of an incurable eye disease that strikes boys. Writing in the August issue of Molecular Therapy, scientists from the UF Genetics Institute describe how they successfully used gene therapy in mice to treat retinoschisis, a rare genetic disorder that is passed from mothers, who retain their sight, to their sons. "Currently there is no treatment," said William Hauswirth,...

Device allows formerly blind patients to see, identify objects HealthDay News -- An "artificial retina" is helping six previously blind patients detect light, identify objects and perceive motion, researchers announced Friday. "If you project a long, 2-foot bar of light on a projector, they can tell which way the light bar moves, right or left, up or down. They can detect motion," said lead researcher Dr. Mark Humayun, an ophthalmology professor at the University of Southern California's...

Moran Eye Center researchers have found gene mutations that result in retinitis pigmentosa (RP), one of the leading causes of blindness. The discovery has raised fears that medications commonly used to treat both heart disease and glaucoma may trigger the eye disease in even those without the mutation because of similarities in what the mutations and the drugs do to the eyes. The research, published in the online version of Human Molecular Genetics Wednesday, says each gene mutation...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
