Finnish researchers have found cellular components in the epithelial tissue of the eye, which have previously been thought to only be present in electrically active tissues, such as those in nerves and the heart. A study at Tampere University found that these components, voltage-gated sodium (Nav) channels, are involved in the renewal of sensory cells in the adjacent neural tissue, the retina.
Sex disparities in ophthalmic research were analyzed in this study that evaluated the representation of female authorships in ophthalmologic journals from 2008 to 2018, with sex assigned according to first name.
This study of 1,400 elementary and junior high school students in Tokyo estimated the rate of nearsightedness.
Researchers at the University of Colorado Anschutz Medical Campus have found that intense light amplifies a specific gene that bolsters blood vessels and offers protection against heart attacks.
Scientists at Trinity College Dublin today announced a major breakthrough with important implications for sufferers of a common eye disease -- dry age-related macular degeneration (AMD) -- which can cause total blindness in sufferers, and for which there are currently no approved therapies.
Giant cell arteritis is an inflammation of the blood vessels that typically occurs in adults over 50 and, if left untreated, can result in irreversible vision loss and death. This study examined whether occurrence of the disorder was associated with race.
The latest iteration of the Huh lab's eye-on-a-chip has a mechanical eyelid to simulate blinking and was used to test an experimental drug for dry eye disease. By incorporating human cells into an engineered scaffolding, the eye-on-a-chip has many of the benefits of testing on living subjects, while minimizing risks and ethical concerns.
Albinism is the best-known of a group of rare genetic disorders that can affect both eyes and skin. Some genes have been identified that are linked to these conditions, but many remain mysterious. Now a team led by UC Davis researchers has identified dozens of these genetic mutations in a screen of gene-targeted 'knockout' mice. The authors hope the work, published Aug. 1, 2019 in Scientific Reports, will be a resource for clinicians specializing in genetic disorders.
With the use of a driving simulator, three commercially available yellow-lens night-driving glasses were compared with clear lenses to examine their ability to detect pedestrians or reduce the negative effects of headlight glare. The study included 22 participants.
The financial and environmental costs of unused portions of drugs from cataract surgery at four surgical sites in the US was investigated in this study.
