Treatments for Advanced Diabetic Retinopathy Show Similar Results
Vitrectomy surgery and intravitreal injections showed similar effectiveness in improving overall vision for patients with advanced diabetic retinopathy, according to results from a clinical trial published in JAMA.
Reassessing How Light Impacts Behavior
Northwestern Medicine investigators have found that a small subset of cells in the retina inhibit the communication of light signals from the eyes to the brain, impacting how light affects daily activity and how the pupils constrict to light.
Site of Flow Resistance in Glaucoma Identified
According to a recent study, elevated ocular pressure in glaucoma is generated in the wall of a small vessel in the eye, the Schlemm’s canal.
Subclinical Macular Degeneration Requires Monitoring
A new Northwestern Medicine study published in PLOS One affirmed the importance of monitoring patients with age-related macular degeneration to ensure their disease does not progress further.
Mapping the Visual System, From Photoreceptors to Brain
With advances in technology and genetics, Feinberg and Northwestern investigators are conducting basic science research to understand just how the retina works in concert with the brain.
Delaying Treatment for Diabetic Eye Condition Could Be Beneficial
Waiting to begin treatments for diabetic macular edema until patients experience vision loss resulted in similar outcomes compared to starting treatments prior to vision loss, according to a recent study published in JAMA.
Eyes May Reveal Early Alzheimer’s Disease
Reduced blood capillaries in the back of the eye may be a new, noninvasive way to diagnose early cognitive impairment, a precursor to Alzheimer’s disease.
Origin of Neuromodulator in the Retina Pinpointed
Northwestern Medicine scientists have discovered that amacrine cells produce nitric oxide, a neuromodulator that regulates blood dilation, in a recently published study.
Newly Formed Blood Vessels May Contribute to Eye Disease
A recent Northwestern Medicine study found that proteins linked to age-related macular degeneration crossed the blood-ocular barrier of aberrantly formed new blood vessels, a process that may contribute to disease.
