DNA testing for congenital cataracts can accurately diagnose diseases linked to childhood blindness

Researchers in the United Kingdom have demonstrated that advanced DNA testing for congenital cataracts can quickly and accurately diagnose a number of rare diseases marked by childhood blindness, according to a study published online today in Ophthalmology, the journal of the American Academy of Ophthalmology.

Early intervention hope for childhood achromatopsia

Researchers have found that children with achromatopsia have milder foveal pathology than their older counterparts, highlighting a potential opportunity for early intervention with gene therapy.

Focal choroidal excavation linked to chorioretinal diseases

Results of a Japanese study show that focal choroidal excavation is present in several ocular diseases, including typical age-related macular degeneration, central serous chorioretinopathy, polypoidal choroidal vasculopathy and idiopathic choroidal neovascularization.

Uniform facedown posturing unnecessary after macular hole surgery

An individualised posturing programme after macular hole surgery can significantly reduce the duration of facedown posturing without compromising outcomes, suggests research published in Retina.

Iodine supplement can reduce central foveal swelling in RP patients with CME

Cystoid macular edema (CME) is a common complication of retinitis pigmentosa (RP), a family of retinal diseases in which patients typically lose night and side vision first and then develop impaired central vision. CME can also decrease central vision.

Vitreous anatomic features characterised

Researchers have found a direct anteroposterior connection between the retrolental and premacular and preoptic spaces that exits in young adults before the occurrence of vitreous degeneration.

Focal choroidal excavation’s coexistence with other choroidal diseases impairs vision

Focal choroidal excavation appears to be relatively common and can have a detrimental effect on vision, a study of Korean patients suggests.

Study to investigate use of OCT in collaboration with Melanoma Institute of Australia

Michelson Diagnostics, the UK based medical device company focused on multi-beam Optical Coherence Tomography ('OCT') technology, has commenced a clinical study to investigate the use of OCT to diagnose basal cell carcinoma in collaboration with the Melanoma Institute of Australia using Michelson's Diagnostics VivoSight system.

Retinal measurements associated with Parkinson’s disease duration

The inner retinal layers in the eyes of patients with Parkinson’s disease are thinner than those of healthy people’s eyes, except for the inner nuclear layer, which is thicker, show the results of a prospective study involving the latest optical coherence tomography methods.

Study establishes innovative approaches to improve vision of young children with brain tumor

Robert Avery, DO, MSCE, of Children's National Health System and colleagues are establishing innovative approaches with technology and medication to improve the vision of young children who have visual pathway glioma, a type of brain tumor.

UAB launches pilot program to detect earlier stages of glaucoma

Glaucoma is a silent disease. It does not hurt, symptoms are slow to develop, and most people do not notice any loss of vision until it is too late. A project by ophthalmologists at the University of Alabama at Birmingham will examine whether a partnership with community-based optometrists will improve detection and treatment of glaucoma, especially for high-risk populations.

Researchers hope to improve treatment, survival rates of ischemic heart disease

Researchers at Case Western Reserve University and University Hospitals Case Medical Center hope to improve treatment and survival rates of ischemic heart disease patients by providing doctors an unprecedented look at the stents they place in coronary arteries.

Binge drinking during pregnancy can lead to fetal alcohol syndrome

Recent data shows that more than 500,000 women in the U.S. report drinking during pregnancy, with about 20 percent of this population admitting to binge drinking.

New optical device puts the power to detect retinal disease in the palm of a hand

A new optical device puts the power to detect eye disease in the palm of a hand. The tool-about the size of a hand-held video camera-scans a patient's entire retina in seconds and could aid primary care physicians in the early detection of a host of retinal diseases including diabetic retinopathy, glaucoma and macular degeneration.

Svelte completes enrollment in drug-eluting coronary stent Integrated Delivery System study

Svelte Medical Systems today announced enrollment of the final patient in the DIRECT II (Direct Implantation of Rapamycin-Eluting stents with bioabsorbable drug Carrier Technology) clinical study. DIRECT II is a prospective, randomized study comparing the safety and efficacy of the Svelte drug-eluting coronary stent Integrated Delivery System (IDS) to the Medtronic Resolute Integrity drug-eluting stent in 159 patients at 19 investigative sites.

Researchers study link between vision loss and Alzheimer's disease

An international team of researchers studying the link between vision loss and Alzheimer's disease report that the loss of a particular layer of retinal cells not previously investigated may reveal the disease's presence and provide a new way to track disease progression.
