Function matters: visual stimulation protects the retina against ischemia
Retinal ischemia is a condition involved in several prevalent retinal degenerative diseases such as glaucoma and diabetic retinopathy, which cause visual impairment and blindness. Current research focuses on the development of neuroprotective strategies against ischemic retinopathies, but
Retroduplication of rhodopsin gene 400 million years ago diversified the photoreception in fishes
Animals utilize light from the environment as important information sources. We can discriminate colors, brightness and shapes of objects by visual system. In addition, animals can detect daily and seasonal changes of the light environment to alter
Biomarkers for Alzheimer’s disease diagnosis: an eye on retinal inflammation
Alzheimer’s disease is one of the most common neurodegenerative disorders. Alzheimer’s disease cases are constantly increasing worldwide due to population aging. Typical symptoms of the disease include memory loss, cognitive deficits, personality and behavior modifications. At the
Eye opener: the gate for immune cells entering the injured eye
Disease or injury to the retina or optic nerve is one of the main causes of blindness worldwide. As such, major research efforts have been invested in finding ways to protect the neuronal cells of the retina
Small fish can help finding drugs to fight retina diseases
About 285 million people are visually impaired in the world. The arising of chronic eye diseases and ageing processes make more people at risk of blindness, 65% of visually impaired people being aged 50 or older. Among
Neurons share the same destiny irrespective of their location: A closer look at PP-MS pathogenesis
Multiple sclerosis (MS) is a disease of the central nervous system, caused by the reaction of immune cells against myelin, a membrane that surrounds the axons of nerve cells. MS is characterized by the presence of inflammatory
OCT provides a better understanding about retinal damage in two rare neuromuscular diseases
The facial – scapular – humeral muscular dystrophy (FSHD) and myotonic dystrophy type 1 (DM1) are neuromuscular diseases with systemic clinical manifestations. Although rare, they are genetic myopathies most frequently encountered in adults. The diagnosis is confirmed
From the gut to the eye: commensal microbes as potential triggers of autoimmune uveitis
Autoimmune uveitis is a group of inflammatory diseases that affect the retina of the eye and related tissues and constitute a major cause of human blindness. It is believed that the disease is triggered by the activation
Can mathematics help defeating acquired blindness?
Sight threatening pathologies of the eye retina, the light sensitive tissue lining the back of the eye, are an increasing health concern in the ageing population. A number of risk factors, including high intraocular pressure, high blood
