Artificial intelligence promising for CA, retinopathy diagnoses

(HealthDay)—A deep learning algorithm can detect metastases in sections of lymph nodes from women with breast cancer; and a deep learning system (DLS) has high sensitivity and specificity for identifying diabetic retinopathy, according to two studies published online Dec. 12 in the Journal of the American Medical Association.

Alternative diagnosis for many referred for optic neuritis

(HealthDay)—Almost 60 percent of patients referred for acute optic neuritis have an alternative diagnosis, according to a study published online Dec. 7 in JAMA Ophthalmology.

Researchers use breakthrough technology to understand eclipse eye damage

In a first-of-its-kind study, Mount Sinai researchers are using adaptive optics (AO) to analyze retinal eye damage from the August solar eclipse on a cellular level. The research could help doctors develop a deeper understanding of this rare condition, called solar retinopathy, which has no currently accepted treatment.

Addressing the burden of glaucoma in Ghana

In each of the past 22 years, Don Budenz, MD, MPH, has gone to Ghana – first right after his fellowship training and now as Chair of the Department of Ophthalmology at UNC and founder of Christian Eye Ministry, an NGO dedicated to preventing and curing blindness in the developing world.

Newly published research provides new insight into how diabetes leads to retinopathy

An international team of scientists led by Professor Ingrid Fleming of Goethe University, Frankfurt, Germany, and including Professor Bruce Hammock of the University of California, Davis, provides new insight into the mechanism by which diabetes leads to retinopathy and often to blindness.

Combating eye injuries with a reversible superglue seal

When a soldier sustains a traumatic eye injury on the battlefield, any delay in treatment may lead to permanent vision loss. With medical facilities potentially far away and no existing tools to prevent deterioration, medics are in a high-stakes race against the clock.

Most glaucoma patients don't ask about medication costs

Less than one-third of patients with glaucoma talk to their doctor about the costs of medications needed to control their disease, reports a study in the December issue of Optometry and Vision Science, the official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

Most older adults willing to play game to monitor vision

(HealthDay)—Many older patients with age-related macular degeneration (AMD) use personal electronic devices, and most are willing to play a game to monitor vision, according to a study published online Nov. 13 in Clinical & Experimental Ophthalmology.

Patients more prone to complain about younger doctors

(HealthDay)—Patients apparently are more likely to complain about younger doctors. Case in point: ophthalmologists.

Trigger for most common form of vision loss discovered

In a major step forward in the battle against macular degeneration, the leading cause of vision loss among the elderly, researchers at the University of Virginia School of Medicine have discovered a critical trigger for the damaging inflammation that ultimately robs millions of their sight. The finding may allow doctors to halt the inflammation early on, potentially saving patients from blindness.

Rods in the retina contribute to daylight vision

An international research team headed by Thomas Münch from Tübingen University found the contribution of rod photoreceptors in mouse retinas to be much greater than previously assumed. Rods cannot distinguish between colours and were thought to become useless as light levels increase, while vision in daylight conditions is based on cone photoreceptors. The new study – published in Nature Communications – shows that rod function can even increase in bright light.

Images used to educate public about leading cause of blindness not realistic, says study

Images used to educate the public about vision loss due to the leading causes of blindness are not fit for purpose, according to a new study from City, University of London.

Data may weigh on pros/Cons of expanded care optometry

(HealthDay)—More than three-quarters of residents living in states where optometrists have been granted expanded scope of practice live within an estimated travel time (ETT) of 30 minutes to the nearest ophthalmologist office, according to a study published online Nov. 22 in JAMA Ophthalmology.

Scientists engineer drug delivery device that treats glaucoma directly inside the eye

Glaucoma, which affects over 60 million people worldwide, can seem easy to treat: medicated eye drops can be used to ease the buildup of fluid in the eye that underlies the condition. If glaucoma is caught early, eye drops can prevent irreversible blindness.

Nanosponges show promise for potentially blinding eye infections

In recent years, the number of eye surgeries for conditions including cataracts and glaucoma has dramatically increased and with it, so has the number of potentially blinding intraocular infections. In a new study, researchers demonstrate using a mouse model that engineered nanosponges can be used to protect eyes from infections caused by Enterococcus faecalis. Enterococcus faecalis contain a toxin called cytolysin, which is found in roughly 50% of isolates that cause post-operative intraocular infections seen in the United States.
