Researchers discovered that fusing Müller glia with adult stem cells can differentiate into ganglion cells, a type of neuron essential for vision. This finding brings hope for recovering the retina's regenerative capacity in humans.
A study of 12 million children found a moderate association between strabismus and anxiety disorder, schizophrenia, bipolar disorder, and depressive disorder. The findings suggest that children with crossed eyes may be at higher risk for developing these mental health conditions.
Scientists identify a specialized zone in Muller glia cells called the citrullination bunker that sequesters damaged proteins, preserving vision. Chronic engagement of this process may lead to retinal degeneration, but inhibiting it could delay or prevent disease.
Researchers at CRCHUM have identified damaged nanotubes connecting pericytes as a major contributor to glaucoma. The study reveals that restoring calcium equilibrium within pericytes can recover vascular and neuronal functions, paving the way for new therapeutic approaches.
A USC discovery demonstrates the safety and efficacy of a stem-cell derived retinal implant for treating advanced dry age-related macular degeneration. The implant successfully improved visual function in some patients and survived without rejection for up to two years.
Researchers at RIKEN have developed a new retinal transplant technique by engineering human-derived retina sheets to lose bipolar cells, allowing better connections to host retinas and improved responses to light. The technique has shown substantial functional improvement in animal studies and is now poised for human clinical trials.
A new study of UK Biobank adults found significantly increased rates of nearsightedness, particularly in children. The study suggests changing environmental factors and gene-environment interactions may be to blame for the rising trend.
A two-year study aims to restore functional vision among veterans and service members with head trauma-related visual dysfunction using immersive virtual reality technology. Researchers will explore the feasibility and benefits of applying new technologies to rehabilitative treatment activities.
Phoebe Lin's research establishes a gut-eye association in animal models, finding that certain interventions can enhance Tregs and decrease eye inflammation. Her five-year grant will investigate how intestinal microbes and the immune system can be rebalanced to treat uveitis.
Researchers have found that people with genetic risk factors for age-related macular degeneration (AMD) have thinner retinas and photoreceptors, even if they haven't yet lost their sight. This early detection could lead to earlier treatment and lifestyle changes to prevent vision loss.
Tiny fixational eye movements, beyond human awareness, are critical for fine details and everyday tasks. Microsaccades cause transient visual suppression during gaze shifts, but vision recovers rapidly at the center of gaze, leading to enhanced overall visibility.
A seven-year study by CooperVision indicates that MiSight 1 day contact lenses slow myopia progression without a rebound effect, even after treatment cessation. The lenses demonstrate sustained slowing of myopia progression across different ages and with varying levels of myopia.
A study to investigate stem cell therapy as a potential treatment for glaucoma, the world's second leading cause of blindness, has received $6.7M in NEI funding. The research team will explore ways to make stem cell-derived neurons survive and integrate into the eye.
A Tanzanian study found that laser treatment (SLT) successfully reduced eye pressure to normal levels in 61% of patients after one year, compared to 31% with daily eye drops. SLT may be an affordable alternative for glaucoma care in Africa.
A research team led by NJIT's Tara Alvarez is enrolling 100 participants with persistent symptoms of convergence insufficiency (CI) post-concussion for clinical trials. The study aims to establish guidelines for diagnosing and treating CI, a disabling eye disorder causing blurred vision, headaches, and cognitive difficulties.
A recent study of 1.5 million Israeli teens found that approximately 1% have lazy eye, with a decline in incidence over the past two decades. Socioeconomic factors and ultra-orthodox upbringing are linked to increased risk, while immigrants from certain countries have a higher prevalence
Researchers tested CER-001 on a human patient with familial LCAT deficiency, showing improved kidney function and stable vision for up to 11 months. The treatment was well-tolerated, but further studies are warranted to prevent kidney progression.
Researchers analyzed da Vinci's artworks and found evidence of intermittent exotropia, a condition that enables monocular vision. This skill may have contributed to his ability to depict depth in his paintings.
A study of 14,000 people with MS found common conditions like fibromyalgia, irritable bowel syndrome, and mood disorders preceding the diagnosis. This research may enable early detection and treatment, possibly slowing disease progression.
A study of over 2,500 adults found that visual impairment is strongly associated with cognitive decline. Maintaining good vision through prevention and treatment may help reduce age-related cognitive changes.
A new study reports the first small molecule targeted therapy for progressive hearing loss in a mouse model of USH3, which causes devastating symptoms. The discovery holds promise for real-world translation and could prevent both sensory deficiencies in USH3 patients.
A new study finds that moderately farsighted preschoolers and kindergarten students perform worse in early literacy than children with normal vision. The researchers hope this research is an important step in clearing up the uncertainty surrounding what to do with these kids.
Researchers at the University of York found that our colour perception changes between seasons and is influenced by environmental factors. The study revealed that unique yellow remains stable across large populations despite individual differences in eye biology.
A study published in JAMA Network found that the medication acetazolamide, combined with a low-sodium weight-reduction diet, improved vision in patients with idiopathic intracranial hypertension. The treatment resulted in modest improvement in visual loss compared to a placebo.
A new study reveals that girls with NF1 are at greater risk of vision loss from brain tumors, while boys are more vulnerable to learning disabilities. The research identifies gender-linked differences in male mice that may help explain these findings.
This year's class of distinguished fellows recognizes outstanding leadership and service in vision research. The ARVO Fellows will be officially inducted at the Association's Annual Meeting, May 1, 2023.
A new report by World Vision highlights the need for direct healthcare investment in families and communities to tackle preventable child and maternal deaths. The organization calls on world leaders to prioritize these efforts to meet Millennium Development Goals (MDGs) 4 and 5 targets.
A new study by George Mason University's Center for Climate Change Communication found that framing climate change as a public health problem resonates with people, even those who don't believe in climate change. The research suggests re-framing the issue helps people better understand and relate to the climate problem.
The Association for Research in Vision and Ophthalmology (ARVO) has announced its inaugural class of Fellows, honoring members who have made significant contributions to vision research and ophthalmology. The ARVO Fellow title recognizes outstanding achievements in leadership, collaboration, and dedication to advancing the field.
Research found that individuals' expectations of recovering from whiplash injuries are crucial in predicting their likelihood of recovery. Patients who expected to make a full recovery were more likely to have fewer disability symptoms six months later.
Parkinson's disease impacts brain's centers of touch and vision, affecting more than just motor control. Functional magnetic resonance imaging (fMRI) reveals widespread abnormalities in somatosensory and visual cortex.
