Multicenter cohort study shows reduced risk of vision-threatening diabetic retinopathy from fenofibrate
A team of researchers at the University of Pennsylvania has found that administration of a drug currently used to reduce cholesterol levels in the bloodstream can reduce the risk of developing proliferative diabetic retinopathy (PDR) from non-proliferative diabetic retinopathy (NPDR).
People with vision impairments up to four times more likely to suffer mental health problems
Research by international development organization Sightsavers, University of Ilorin, and the Kogi State Ministry of Health, in Nigeria has revealed links between vision impairment and poor mental health.
Sound can stimulate blind retina to transmit signals to the brain via an ultrasonic retinal prosthesis
Retinal degenerative diseases, caused by progressive degeneration of the light-sensitive photoreceptors in the retina, is one of the major causes of vision loss and blindness, affecting tens of millions of people worldwide. Although the rods and cones which are the light-sensitive cells of the retina have completely degenerated, the neural circuitries connected to the brain are mostly well preserved, providing the opportunity to restore vision by directly stimulating the retinal neurons.
Risks to children's eyesight and general health linked to increased screen time
A new study shows that children's digital screen time has increased significantly during the COVID-19 pandemic, resulting in potential risks to physical health.
Vision scientists discover new angle on path of light through photoreceptors
Researchers at the National Eye Institute (NEI) have discovered that power-producing organelles in the eye's photoreceptor cells, called mitochondria, function as microlenses that help channel light to these cells' outer segments where it's converted into nerve signals.
Mayo Clinic Q and A: Relief for dry eyes
It is common to have dry and watery eyes at the same time. Watery eyes is the No. 1 complaint of those with dry eyes. That's because when your eyes get dry enough, they act as if there is something in them and try to flush it out. And this leads to watery eyes.
Depression linked to more severe dry eye disease
Depression is associated with more severe dry eye disease (DED) symptoms and overall signs, according to a study published online March 10 in JAMA Ophthalmology.
Topical therapeutic effective in alleviating allergic conjunctivitis symptoms
Reproxalap may be a viable new therapy option for patients with allergic conjunctivitis, according to a study published in Clinical Ophthalmology.
Perspectives on diabetic retinopathy from advanced retinal vascular imaging
Diabetic retinopathy (DR) is a microvascular complication of diabetes and one of the leading causes of blindness in patients aged 20–74. DR is estimated to affect one-third of the over 460 million diabetic patients worldwide. As a progressive and vision-threatening condition, its late-stage complications including vitreous haemorrhage, traction retinal detachment, neovascular glaucoma, and vision loss.
Use of ellipsoid zone width for predicting visual prognosis after cataract surgery in patients with retinitis pigmentosa
To predict the visual prognosis of cataract surgery in patients with retinitis pigmentosa by measuring ellipsoid zone (EZ) width using spectral-domain optical coherence tomography.
