Early detection of macular degeneration with electroretinography


In a study that compared patients with dry and wet AMD to those with healthy eyes researchers determined that electroretinography (ERG) is able to detect both wet and dry forms of macular degeneration. The confirmation of this will hopefully lead to earlier treatment in patients before the disease can advance. While macular degeneration does not […]

Color vision may be affected by high blood pressure


Japanese researchers may have discovered a link between high blood pressure and impaired color vision. Saitama Medical University researchers in Japan studied the relationship between color vision, eye disease, heart-related risk factors and lifestyle habits among 872 men between the ages of 20 and 60 years who were on active duty in the Japanese Self […]

Google’s smart lens technology pairs with Alcon


Google has licensed its “smart lens” technology to Alcon for all ocular medical uses. The collaboration between the technology giant and the eye care giant will include developing a “smart lens” to address ocular conditions. The advances that Google has made in miniaturization of electronics will help Alcon in its endeavors to improve the ways […]

Could blood pressure meds raise risk of developing AMD?


A recent, long-term study points to a possible link between vasodilators and beta blockers and the development of age-related macular degeneration (AMD). Researchers at the University of Wisconsin School of Medicine conducted a 25-year study, which included t 5,000 adults who were between the ages of 43 and 86. Eye exams were conducted every 5 […]

Alcohol Impairs Night Vision


Alcohol not only impairs coordination and driving ability, it actually impairs night vision as well. The perception of halos and other nighttime related visual disturbances is increased when alcohol is consumed. The ethanol in an alcoholic drink passes into the tear and disrupts the lipid layer, which then increases the evaporation of the aqueous part of the tear. […]

Molecule enables blind mice to see the light


Mice injected with a molecule developed by neuroscientists at the University of California at Berkeley were able to react to light. The researchers are hopeful that patients injected with the molecule would be able to be fitted with smart goggles which would then be able to interpret the surroundings into a photo simulation. The molecule […]

Sensor placed in eye can track intraocular pressure changes


A low-power sensor has been developed by researchers at the University of Washington that can be placed permanently in the eye and can monitor changes in eye pressure. This lens is implanted during cataract surgery and can immediately detect changes in pressure within the eye. The sensor transmits data via radio frequency waves. Glaucoma is often […]

Cerebrospinal fluid pressure may hold key to glaucoma


Researchers have discovered that cerebrospinal fluid (the fluid surrounding the brain) plays an important role in maintaining proper eye function. This discovery could lead to possible treatments for glaucoma. By raising the pressure of the cerebrospinal fluid in rats, researchers were able to counterbalance elevated intraocular pressure. This in turn, kept the optic nerve from […]

Cataract Awareness during the month of June


Despite being manageable and treatable, cataracts are the leading cause of blindness in the world. In the United States alone, more than 24 million American aged 40 and older are affected. On the bright side, cataract surgery has 95% success rate and is one of the most commonly performed surgeries in the United States. The […]

‘Sticky-trap’ therapy helps treat diabetic retinopathy


Researchers at the University of Toronto in Canada have developed a new therapy called ‘sticky-trap’ to treat diabetic retinopathy. ‘Sticky-trap’ is injected into the eye and the binding component within it attaches to the surface of cells and shuts down the abnormal blood vessels within the eye. Diabetic retinopathy causes vision loss when the extra, […]
