Ophthalmology News and Research

RSS

Ophthalmology is the specialized field of medicine that focuses on the health of the eye. It includes the anatomy, physiology and diseases that may affect the eye. Historically, the science of ophthalmology encompassed all aspects of visual function, both in health and in illness. Additionally, ophthalmology also includes animal eyes as ocular function and optic diseases are similar among humans and animals.

Proteins in the eye may predict which macular degeneration patients need life-long treatment

In a study of eye fluid from 38 patients, Johns Hopkins Medicine researchers say they have found that levels of a specific protein appears to help accurately predict whether people with the wet form of age-related macular degeneration may need lifelong, frequent eye injections to preserve vision or if they can be safely weaned off the treatments.

Immune particles from llama blood could offer protection against several COVID-19 variants

Mount Sinai-led researchers have shown that tiny, robust immune particles derived from the blood of a llama could provide strong protection against every COVID-19 variant, including Omicron, and 18 similar viruses including SARS-CoV-2 and SARS-CoV-1, which was responsible for the 2003 SARS outbreak.

Researchers identify a signature of three genes linked to positive response to blood cancer therapy

Mount Sinai researchers have for the first time identified genes that predict a good response to a vital new therapy for a blood cancer that can have serious side effects for some patients.

Anorexia patients show notable reductions in three critical measures of the brain, study reveals

Eating disorders are often misunderstood as lifestyle choices gone awry or oversimplified as the unfortunate result of societal pressures. These misconceptions obscure the fact that eating disorders are serious and potentially fatal mental illnesses that can be treated effectively with early intervention.

IOB's new scRNA-seq protocol provides a snapshot of the cell transcriptome at unprecedented resolution

Single-cell RNA-sequencing (scRNA-seq) shows which genes are turned on in a cell and what their level of transcription is. This allows in-depth assessment of the biology of individual cells, and detection of changes that may indicate disease.
