In diagnosis of giant cell arteritis, cranial ultrasound may replace temporal artery biopsy
A new study presented for the first time at the European League Against Rheumatism Annual Congress (EULAR 2014), shows that cranial ultrasound has a greater sensitivity than temporal artery biopsy,*…
Light-sensitive retina created with human stem cells
With human stem cells, a team has created a miniature human retina in a petri dish with functioning photoreceptor cells. They hope this technique could restore vision one day.
Study could help improve retinal prosthetic devices
In laboratory tests, researchers have used electrical stimulation of retinal cells to produce the same patterns of activity that occur when the retina sees a moving object.
Jigsaw effect in glaucoma patients proves it is a brain disease
Findings from a new study published in Translational Vision Science & Technology (TVST show the brain, not the eye, controls the cellular process that leads to glaucoma.
The American Academy of Ophthalmology offers guidance to help improve public understanding of cataracts
Cataract is one of the leading causes of blindness in the United States. Approximately 24.
Generic version of drug to treat blindness could save medicare billions
If all eye doctors prescribed the less expensive of two drugs to treat two common eye diseases of older adults, taxpayer-funded Medicare plans could save $18 billion over a 10-year period, say…
Two gene mutations cause melanoma of the eye
Researchers at the University of California, San Diego School of Medicine have identified a therapeutic target for treating the most common form of eye cancer in adults.
Mathematical model may lead to cure for dry eye
A treatment for dry eye – a burning, gritty condition that can impair vision and damage the cornea – could some day result from computer simulations that map the way tears move across the surface of…
The visual cortex processes auditory information too
Scientists studying brain process involved in sight have found the visual cortex also uses information gleaned from the ears as well as the eyes when viewing the world.
New neural pathway identified in eyes that aids in vision
A type of retina cell plays a more critical role in vision than previously known, a team led by Johns Hopkins University researchers has discovered.
Ocular sarcoidosis an increased risk for male smokers
Cigarette smoking and male sex are significant risk factors for developing ocular sarcoidosis, according to a new study presented at the 2014 American Thoracic Society International Conference.
Artificial intelligence lenses for the blind created in Mexico
Combining computational geometry, artificial intelligence, geo and ultrasound techniques, among others, scientists from the Center for Research and Advanced Studies (CINVESTAV) created a…
2 JAMA Ophthalmology studies focus on glaucoma medication adherence
Electronic Monitoring Documents Lack of Medication Adherence in Patients with GlaucomaElectronic monitoring to measure medication adherence by patients with glaucoma documented that a sizable…
New clinical and real world data further confirms the safety profile and efficacy of Lucentis (ranibizumab) and supports a flexible dosing approach
Real world data presented by Novartis at the 2014 Association for Research in Vision and Ophthalmology (ARVO) Conference this week further support the well-established safety and efficacy profile…
GPs urged to ensure every squint is checked with a red reflex test to rule out eye cancer
A children’s cancer charity is calling for all squints in babies and young children to be checked with a red reflex test to rule out eye cancer.
Bioengineering for retinopathy: plugging leaky blood vessels to save vision
A new drug approach has been developed for safer clean-up of deformed blood vessels in the eye by a research team at the Lunenfeld-Tanenbaum Research Institute, Mount Sinai Hospital in Toronto.
Neurotrophic keratitis: Preliminary data from the REPARO study
Dompé, an Italian biopharmaceutical company, is creating new prospects for the treatment of corneal ulcers in patients affected by neurotrophic keratitis, an untreatable rare eye condition that…
Post-operative healing aided by new gel-based eye fluid
In an effort to avoid serious side effects suffered after surgery to repair retinal detachment, vision scientists have developed a new product to help stabilize the eye while it heals.
