Eyes Might Be Windows To The Risk Of Alzheimer’s Disease

Locus coeruleus (LC) tau accumulation begins early. Targeting LC (dys)function might improve early identification for Alzheimer’s disease (AD) risk. Pupillary responses during cognitive tasks are driven by the LC and index cognitive effort. Despite equivalent task performance, adults with mild cognitive impairment (MCI) have greater pupil dilation/effort; during digit span than cognitively normal (CN) individuals.…

Retina

Birth Of Vision From The Retina To The Brain

How is the retina formed? And how do neurons differentiate to become individual components of the visual system? By focusing on the early stages of this complex process, researchers at the University of Geneva (UNIGE); Switzerland, in collaboration with the École Polytechnique Fédérale de Lausanne (EPFL), have identified the genetic programs governing the birth of…

Altered Visual Processing A Nonverbal Marker Of Autism

Patients with autism may have altered visual processing; which could serve as an objective, nonverbal neural marker of the disorder, new research suggests. Using electroencephalography (EEG), investigators found that adults with autism have differences; in the part of the brain that processes visual information and these differences used to predict which individuals have autism. “This…

Blindness

Poor Diet Can Lead To Blindness In Young Patients

An extreme case of “fussy” or “picky” eating caused a young patient’s blindness; according to a new case report published in Annals of Internal Medicine. The University of Bristol researchers who examined the case recommend clinicians consider nutritional optic neuropathy in any patients with unexplained vision symptoms and poor diet, regardless of BMI, to avoid…

Online Information

Online Information On Diabetic Retinopathy Lacks Accuracy

Patients at risk for Diabetic Retinopathy or with a new diagnosis of DR may attempt to supplement information; from their ophthalmologist and primary care physicians by conducting research on the internet. The Pew Research Center found that 72% of adults who use the internet search for health-related material. Studies have found that online information can…

Eyelash

Emergency Procedures, Serious Infections Caused By Eyelash Treatments

One of the most commonly reported problems is a condition known as blepharitis; a chronic inflammatory disorder of the eyelids that arises due to bacterial overgrowth on the eyelash; explains Consultant Ophthalmic and Oculoplastic Surgeon Elizabeth Hawkes in a recent article. Research carried out by Huda Beauty demonstrated just how committed British women; are to…

Ocular Hypertension

Ophthalmic Solution Lowers IOP In Glaucoma, Ocular Hypertension

Glaucoma is the leading cause of irreversible blindness worldwide, affecting more than 64 million people aged 40-80 years. Glaucoma can arise through various etiologies; but vision loss is ultimately due to optic nerve damage and the progressive death of retinal ganglion cells. Intraocular pressure (IOP); which becomes elevated owing to abnormally high resistance to trabecular…

Dry Eye

Poor Acuity Linked To Vision-Related Symptoms In Dry Eye

Identification of the association of specific signs of dry eye disease with specific visual function; deficits may allow for more targeted approaches to treatment. The purpose of this study was to explore the association of dry eye signs; and symptoms with visual acuity (VA) and contrast sensitivity in the Dry Eye Assessment and Management study. Poor…

Reticular pseudodrusen

Reticular Pseudodrusen A Risk For More Rapid AMD Progression

Patients with reticular pseudodrusen (RPD)-associated age-related macular degeneration (AMD) are at increased risk of progression to geographic atrophy, researchers say. “Ophthalmologists have known about RPD and their relationship to AMD for over 30 years; but the diagnosis rarely made,” Dr. Amitha Domalpally of the University of Wisconsin-Madison School of Medicine and Public Health said by…

Retina-on-a-chip

Retina On-A-Chip Provides Powerful Tool For Studying Eye Disease

The development of a retina-on-a-chip; which combines living human cells with an artificial tissue-like system, has described today in the open-access journal eLife. However, this cutting-edge tool may provide a useful alternative to existing models for studying eye disease; and allow scientists to test the effects of drugs on the retina more efficiently. However, many…

Genetic code

Researchers Reveal New Insights Into Retina’s Genetic Code

Australian scientists have led the development of the world’s most detailed genetic code the human retina; providing new insights which will help future research to prevent and treat blindness. The retina is the latest part of the human body and the first part of the eye to be mapped as part of the Human Cell…

Augmented Reality Glasses May Help People With Low Vision Better

Nearly one in 30 Americans over the age of 40 experience low vision significant visual impairment that can not; be corrected with glasses, contact lenses, medication or surgery. However, in a new study of patients with retinitis pigmentosa; an inherited degenerative eye disease that results in poor vision, Keck School of Medicine of USC researchers…
