Researchers report startling glaucoma protein discovery

A discovery in a protein associated with glaucoma was so unheard of that for over two years, researchers ran it through a gauntlet of lab tests and published a new research paper on it. The tests validated what they initially saw.

Curve-eye-ture: How to grow artificial corneas

Scientists at Newcastle University, UK, and the University of California have developed a new method to grow curved human corneas improving the quality and transparency - solely by controlling the behaviour of cells in a dish.

A country's prevalence of visual impairment, blindness associated w level of socioeconomic develop

In an analysis of data for 190 countries and territories, those with higher levels of socioeconomic development had a lower prevalence of visual impairment and blindness, according to a study published by JAMA Ophthalmology.

Clinical study success for novel contact lens device aimed to improve glaucoma treatment

A novel contact lens device developed by University of Liverpool engineers to improve the treatment of glaucoma has been found to reliably track pressure changes in the eye and be wearable by people who took part in its first clinical study.

Genetic testing recommended for children considered at risk for most common eye cancer

Children who are considered to be at risk of developing eye cancer should receive genetic counseling and testing as soon as possible to clarify risk for the disease. This is the consensus of leading ophthalmologists, pathologists and geneticists, who worked for two years to develop the first U.S. guidelines on how to screen for the most common eye tumor affecting children. The goal is to ensure retinoblastoma is detected at the earliest possible stage so ophthalmologists can save the lives and vision of more children.

EHRs take up substantial time for ophthalmologists

(HealthDay)—A substantial portion of the time that ophthalmologists spend with patients is spent on electronic health record (EHR) use, according to a study published online Oct. 12 in JAMA Ophthalmology.

Study indicates proof of concept for using a surrogate liquid biopsy to provide genetic profile of retinoblastoma tumors

Retinoblastoma is a tumor of the retina that generally affects children under 5 years of age. If not diagnosed early, retinoblastoma may result in loss of one or both eyes and can be fatal. Unlike most cancers that are diagnosed using a biopsy, retinoblastoma tumors cannot be directly biopsied. Although it is one of the first cancers to have its genetic origin identified, ocular oncologists have not been able to use this information to optimize treatment since they can only access the tumor if the affected eye is removed (called enucleation) in the course of treatment.

Farsighted children struggle with attention, study finds

Farsighted preschoolers and kindergartners have a harder time paying attention and that could put them at risk of slipping behind in school, a new study suggests.

Combo Tx superior for polypoidal choroidal vasculopathy

(HealthDay)—Combination therapy consisting of ranibizumab plus verteporfin photodynamic therapy (vPDT) is superior to ranibizumab monotherapy for treatment of eyes with polypoidal choroidal vasculopathy (PCV), according to a study published online Oct. 5 in JAMA Ophthalmology.

A close look at efforts to turn back the growing problem of myopia

Several studies indicate that the prevalence of myopia is increasing in the U.S. and worldwide, and researchers project that the trend will continue in the coming decades. Otherwise known as nearsightedness, myopia occurs when the eye grows too long from front to back. Instead of focusing images on the retina—the light-sensitive tissue in the back of the eye—images are focused at a point in front of the retina. As a result, people with myopia have good near vision but poor distance vision.

Most ophthalmologists write few opioid prescriptions

(HealthDay)—Most ophthalmologists write no more than 10 opioid prescriptions annually, with a mean supply per prescription of five days, according to a study published online Oct. 5 in JAMA Ophthalmology.

New drug reduces rate of progression of incurable eye disease

An international study including researchers from the Centre for Eye Research Australia (CERA) has found a way to slow the progression of dry age-related macular degeneration (AMD) - one of the most common causes of vision loss in people over the age of 50.

Gene therapy shows promise for reversing blindness

Most causes of untreatable blindness occur due to loss of the millions of light sensitive photoreceptor cells that line the retina, similar to the pixels in a digital camera.

Radical research raises hopes for eye disease treatment for premature babies

Ground-breaking research by Monash University scientists has demonstrated the previously unknown existence of a disease-fighting immune cell in the eye and points to potential novel ways of treating eye disorders in premature babies and diabetic adults.

Eyebank corneal tissue prep may increase infection risk

(HealthDay)—Donor rim cultures are more likely to have detectable Candida growth in endothelial keratoplasty-processed eyes than for other uses, according to a study published online Sept. 28 in JAMA Ophthalmology.
