Better Eyes for Longer Life without Alzheimer's research project opens to everyone

The Alzheimer's Association puts a fine point on the truism that the risk of developing Alzheimer's disease or some other form of cognitive impairment increases with age: (They expect that) 7 million of those who reach 85 by 2050 will have Alzheimer's disease (AD).

Carl Zeiss Meditec to invest in Oraya Therapy for treatment of wet AMD

Carl Zeiss Meditec AG and Oraya Therapeutics, Inc. jointly announced today that the companies have entered into a collaboration agreement under which Carl Zeiss Meditec will provide funding to Oraya over a period of up to two years for the implementation of Oraya’s growth strategy, and in turn receive rights in the company reaching up to a majority stake after two years.

Caution advised over OCT measurement of thick choroid

Enhanced depth imaging optical coherence tomography is consistent for measuring choroidal thickness, researchers confirm, but its accuracy may be impaired in eyes with a very thick choroid.

Optical coherence tomography methods comparable for AMD assessments

There is good accordance between spectral-domain and time-domain optical coherence tomography image assessments of eyes treated for neovascular age-related macular degeneration, show study findings.

OCT enhances neovascular subtype detection in AMD

Researchers recommend the inclusion of optical coherence tomography anatomic classification with fluorescein angiography grading to identify initial neovascular lesion subtypes in newly diagnosed age-related macular degeneration.

Second treated eyes with nAMD functionally more important than first eyes

A real-world study of the characteristics of second treated eyes in patients with neovascular age-related macular degeneration given ranibizumab in the UK National Health Service has shown that these eyes start off with better baseline visual acuity than first treated eyes and, despite a poor response to therapy, maintain this advantage.

Stanford scientists find new way to predict progression of AMD

Stanford University School of Medicine scientists have found a new way to forecast which patients with age-related macular degeneration are likely to suffer from the most debilitating form of the disease.

Treating wet AMD with gold nanoparticles: an interview with Jim Taylor, CEO, Oraya Therapeutics

Wet AMD is characterized by abnormal growth of blood vessels in the macula (the area of the eye containing vision-enabling photoreceptors), and is responsible for the vast majority of severe vision loss in the industrialized world.

Reticular pseudodrusen predicts late-stage AMD

Reticular pseudodrusen increases the likelihood of people with choroidal neovascularisation in one eye also developing late-stage, age-related macular degeneration in the other eye, researchers report.

Central sclera thickening characterises dome-shaped macula

A dome-shaped macula appears to result from the relative thickening of the central macular sclera, researchers have found.

Macular ischaemia, retinal thinning linked to reduced visual function in diabetic retinopathy

Macular ischemia and retinal thinning are associated with reduced visual function in patients with diabetic retinopathy, research suggests.

Study examines ocular changes seen in astronauts to treat spaceflight-induced visual impairment

To reduce and better treat spaceflight-induced visual impairment, University of Houston (UH) optometrists are collaborating on a NASA study that examines ocular changes seen in a number of astronauts.

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.
