Nerve fibre loss and rise in key immune cells on eye surface may signal 'long COVID'
Nerve fibre loss and an increase in key immune (dendritic) cells on the surface of the eye (cornea) may be an identifying feature of 'long COVID', suggests a small study published in the British Journal of Ophthalmology.
Tailored optical stimulation for the blind
Stimulation of the nervous system with neurotechnology has opened up new avenues for treating human disorders, such as prosthetic arms and legs that restore the sense of touch in amputees, prosthetic fingertips that provide detailed sensory feedback with varying touch resolution, and intraneural stimulation to help the blind by giving sensations of sight.
Vision impairment tied to cognitive decline
Worse visual acuity, contrast sensitivity, and stereo acuity impairment are associated with an increased risk for cognitive decline in older, community-dwelling individuals, according to a study published online July 16
10 child eye problems parents should never ignore
Childhood is a crucial time for developing healthy vision. Symptoms of eye problems in children can sometimes be obvious and other times may be more subtle. It’s important to detect and treat issues early, while vision is still developing. Regular screenings with a pediatric ophthalmologist can help protect your child’s vision as they grow.
What can cause sticky eyes?
People may use the term sticky eyes to describe when a wet or sticky discharge causes the eyelid to feel as though it is stuck together. The condition can occur due to various conditions that affect the eyes, such as styes, conjunctivitis, and blepharitis.
First report of COVID-19 orbital involvement
A severe skin infection in the orbital area (around the eye) may represent an unusual complication of COVID-19, according to a patient report published in The Journal of Craniofacial Surgery.
Nickelodeon and onesight team up for kids eye health campaign
Launching August 1 and culminating on World Sight Day, October 14, the “Framing The Future” campaign will educate kids and families on the importance of eye health, clear vision and access to vision care on a global scale, through multi-property programming, original short form and digital content.
Inflammation of the eye after drug withdrawal in children with arthritis
Jens Klotsche and colleagues shared new data at the 2021 EULAR congress analyzing the risk of uveitis events after discontinuing disease-modifying antirheumatic drugs (DMARD) in children with one of two JIA categories: extended oligoarthritis and rheumatoid factor (RF)-negative polyarthritis.
Cataracts: Common, and easy to treat
Many aging Americans can have their vision dimmed by cataracts, but the good news is that they're easily treated, one expert says.
The vision: Tailored optical stimulation for the blind
Scientists in a European collaboration have shown that optic nerve stimulation is a promising neurotechnology to help the blind, with the constraint that current technology has the capacity of providing only simple visual signals. A new stimulation protocol of the optic nerve is a promising way for developing personalized visual signals.
