Retinal disease

Retinal Disease In Unique Research Project

Researchers at the Lions Eye Institute (LEI) laboratory model of a rare type of retinal disease; paving the way for new treatment pathways. Cone dystrophy with supernormal rod response (CDSRR); is an inherited disease which emerges in childhood and will eventually cause life-long visual loss. Symptoms include central vision loss; extreme sensitivity to light; night…

Dry Eye Disease And Diabetes New study Reveals Scale Of Issue

Diabetes is a debilitating health condition which is to reach epidemic proportions in the next 20 years. According to the World Health Organisation; 108m people around the world had diabetes in 1980; by 2014 that figure was 422m. Three years later in 2017, 425m people worldwide are living with the disease and this figure is…

Retina

First Cellular Atlas Of The Primate Retina

When it comes to understanding how neurons connect to form circuits in the brain; scientists for decades have turned to the retina of the humble laboratory mouse as an ideal model organism. But as a model for vision and vision-related diseases. And though the fovea well-studied for decades researchers have demonstrated both functional; structural specialization…

Gene therapy

Gene Therapy Operation For Macular Degeneration

In the medicine field gene therapy (also called human gene transfer); is the therapeutic delivery of nucleic acid into a patient’s cells as a drug to treat disease. The first attempt at modifying human DNA was performed in 1980 by Martin Cline, but the first successful nuclear gene transfer in humans; approved by the National Institutes of…

Vision loss

Heavy Smoking Could Lead To Vision Loss

vision loss is a decreased ability to see to a degree that causes problems not fixable by usual means; such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses. The Centers for Disease Control and Prevention estimates that 34.3 million;…

Corneal Dystrophy

Improve Diagnostics And Treatment For Corneal Dystrophy

Corneal dystrophy is a group of rare hereditary disorders characterized by bilateral abnormal deposition of substances; in the transparent front part of the eye called the Corneal dystrophy; may not significantly affect vision in the early stages. However, it does require proper evaluation and treatment for restoration of optimal vision. Corneal dystrophies usually manifest themselves…

Optic nerve injury

Appears To Aid Recovery After Optic Nerve Trauma

When a car crash or explosion results in an optic nerve injury; eliminating an enzyme known to promote inflammation appears to aid recovery, scientists report. They have shown for the first time in a mouse model of tough-to-treat optic nerve trauma, that removing the enzyme arginase 2; which increases with injury; decreases neuron death in…

Smartphones

Capture Photographs Of Patients Eyes Risk Misdiagnosis

Clinicians who use smartphones to capture photographs of patients’ eyes risk misdiagnosis if they base their decisions on objective data extracted from non-calibrated cameras; according to new research published this week in the Nature journal Scientific Reports. Clinicians increasingly use smartphones in conjunction with ophthalmic imaging equipment, such as the eyepiece of a slit lamp, because of their…

Macular degeneration

New Biomarker For Age-Related Macular Degeneration

Age-Related Macular Degeneration Macular degeneration, also known as age-related macular degeneration (AMD or ARMD); is a medical condition which may result in blurred or no vision in the center of the visual field. Early on there are often no symptoms. Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. While it does not result in complete blindness. Researchers from…

Scientists First To Pinpoint A Cause Of Pigmentary Glaucoma

An international team of researchers has identified a gene responsible for the onset of pigmentary glaucoma, which may lead to new therapies for the condition. “People who traditionally we wouldn’t think of having glaucoma young males in their 20s and 30sec are at particular risk for this form of the disease and of losing their vision,”…

Microscopic Eye Movements Affect How We See Contrast

It is often difficult for a driver to see a person walking on the side of the road at night especially if the person is wearing dark colors. One of the factors causing this difficulty is a decrease, in contrast, making it hard to segment an object; such as a person, from its background. Researchers…

Gonococcal Eye

Gonococcal Eye Infections In Newborns Advised

The US Preventive Services Task Force (USPSTF) makes recommendations about the effectiveness of specific preventive care services for patients without obvious related signs or symptoms. It bases its recommendations on the evidence of both the benefits and harms of the service and an assessment of the balance. The USPSTF does not consider the costs of…
