New findings on astronaut vision loss

New findings on astronaut vision loss

ScienceDaily (May 30, 2012) — Could vision changes experienced by astronauts be linked to a vitamin B-12 or folate deficiency? While investigating the vision changes recently identified in astronauts, nutritional assessment data showed similarities to symptoms that occur with vitamin deficiencies, according to a new study published in the March edition of The Journal of Nutrition . Approximately 20 percent of astronauts living on the International Space Station have reported post-flight vision changes. Continue reading

Researchers have created glasses that indicate obstacles to patients with visual handicaps

ScienceDaily (May 28, 2012) — People with moderate visual impairment, particularly those who have difficulty perceiving the full extent of their surroundings, could use the ingenious device that these UC3M scientists have created. “This device is aimed at people who would bump into everything that they fail to see because of their loss of visual field, caused by glaucoma, retinal pathologies, etc.,” states the head of the project Professor Ricardo Vergaz, of UC3M’s Electronics Technology Department.

Future treatment for nearsightedness — compact fluorescent light bulbs?

ScienceDaily (May 8, 2012) — Researchers at the University of Alabama at Birmingham hope to one day use fluorescent light bulbs to slow nearsightedness, which affects 40 percent of American adults and can cause blindness. In an early step in that direction, results of a study found that small increases in daily artificial light slowed the development of nearsightedness by 40 percent in tree shrews, which are close relatives of primates Continue reading

Avastin has similar effect to Lucentis in treating most common cause of blindness in the developed world

Avastin has similar effect to Lucentis in treating most common cause of blindness in the developed world

ScienceDaily (May 6, 2012) — The one year results from a study into whether two drug treatments (Lucentis and Avastin), are equally effective in treating neovascular or wet age-related macular degeneration (wet AMD), have been reported May 6 at an international research meeting in Fort Lauderdale, Florida. The findings will also appear online shortly in the leading journal Ophthalmology. Wet AMD is a common cause of loss of vision in older people Continue reading

Breakthrough in IOP regulation in fight against glaucoma

Breakthrough in IOP regulation in fight against glaucoma

ScienceDaily (Apr. 5, 2012) — A six-year collaboration between two faculty members of Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine has yielded new insight regarding the regulation of intraocular pressure (IOP) in glaucoma — an irreversible blinding disease that causes progressive visual impairment due to optic nerve damage and is the leading cause of blindness worldwide. The findings are published in the April 4, 2012 issue of PLoS ONE , an open-access peer-reviewed scientific journal, produced by the Public Library of Science. Continue reading
