Ophthalmology News and Research

RSS

Ophthalmology is the specialized field of medicine that focuses on the health of the eye. It includes the anatomy, physiology and diseases that may affect the eye. Historically, the science of ophthalmology encompassed all aspects of visual function, both in health and in illness. Additionally, ophthalmology also includes animal eyes as ocular function and optic diseases are similar among humans and animals.

Functional ultrasound imaging can reveal brain activity maps of mice for specific behaviors

In a study published in Neuron, Emilie Macé from Botond Roska's group and collaborators demonstrate how functional ultrasound imaging can yield high-resolution, brain-wide activity maps of mice for specific behaviors.

Electrical impulses to the olfactory bulb can provide sense of smell, research shows

Physicians at Massachusetts Eye and Ear have, for the first time, induced a sense of smell in humans by using electrodes in the nose to stimulate nerves in the olfactory bulb, a structure in the brain where smell information from the nose is processed and sent to deeper regions of brain.

Trial results show minimally invasive retinal detachment improves outcomes in patients

A minimally invasive treatment for retinal detachment gives patients sharper vision, less distortion and reduced side-effects, according to the findings of a randomized controlled trial performed at St. Michael's Hospital in Toronto.

AI and Big Data enable better diagnosis, personalized treatment of eye diseases

"Exactly one year ago, we spoke about the fact that, in future, it will be possible to diagnose diabetes from the eye using automatic digital retinal screening, without the assistance of an ophthalmologist – 12 months on, MedUni Vienna is right in the middle of this digital revolution." These were the words used by Ursula Schmidt-Erfurth, Head of MedUni Vienna's Department of Ophthalmology and Optometrics to open today's press conference about the ART-2018 Specialist Meeting on new developments in retinal therapy, which is to take place on 1 December.

Breakthrough technology offers new hope to people with glaucoma, retinitis and macular degeneration

In January 2009, the life of engineer Michel Meunier, a professor at Polytechnique Montréal, changed dramatically. Like others, he had observed that the extremely short pulse of a femtosecond laser (0.000000000000001 second) could make nanometer-sized holes appear in silicon when it was covered by gold nanoparticles.

Study evaluates second-hand marijuana smoke exposure among children

In a study designed to evaluate second-hand marijuana smoke exposure among children--a topic that scientists have not yet widely addressed--researchers at the Icahn School of Medicine at Mount Sinai found that nearly half of children whose parents smoked marijuana showed evidence of second-hand marijuana smoke exposure.

Researchers develop tool that speeds up analysis and publication of biomedical data

Researchers at the Icahn School of Medicine at Mount Sinai have developed a tool that speeds up the analysis and publication of biomedical data from many months or years to mere minutes, transforming the way researchers communicate results of their studies.

Chronic dry eye can slow reading rate and disrupt day to day tasks

Johns Hopkins researchers report that chronic dry eye, a condition in which natural tears fail to adequately lubricate the eyes, can slow reading rate and significantly disrupt day to day tasks that require visual concentration for long periods of time.

Calcified nodules in the retina increase risk for progression to late stages of AMD

Calcified nodules in the retina are associated with progression to late stages of age-related macular degeneration.

NEI investigators combine two imaging modalities to view the retina in unprecedented detail

By combining two imaging modalities--adaptive optics and angiography--investigators at the National Eye Institute can see live neurons, epithelial cells, and blood vessels deep in the eye's light-sensing retina.

Computer games and a summer birthday linked to increased risk of myopia in childhood

According to a new study by researchers in King's School of Life Course Sciences, time spent playing computer games and being born in the summer are both linked to an increased risk of developing short or near sightedness (myopia) in childhood.
