Electroretinography (ERG) is an ophthalmic diagnostic method used to determine whether the retina is functioning normally. It is widely employed for diagnosing hereditary retinal diseases or assessing retinal function decline.

Cell replacement therapy offers new hope for millions of people affected by retinal degenerations (RDs)—a group of blinding conditions caused by the loss of light-sensing photoreceptor cells in the retina. Among the most promising approaches is the transplantation of stem cell-derived partially differentiated photoreceptor cells, known as precursor cells, to replace those lost to disease. But a persistent hurdle remains: Many of the transplanted cells do not survive long enough to integrate or restore vision.

The retina places a large energy demand on the body, in part due to the activity of photoreceptors.

A new study from Washington University School of Medicine in St. Louis identifies a possible way to slow or block progression of age-related macular degeneration, a leading cause of blindness in people over age 50. The study appears in the journal Nature Communications.

Capsular tension ring (CTR) implantation is associated with improved stability of the intraocular lens (IOL), according to a review published online June 12 in JAMA Ophthalmology.

An Aston University optometrist, Professor James Wolffsohn, has determined an optimum blinking exercise routine for people suffering with dry eye disease, and has developed a new app, MyDryEye, to help them complete the routine to ease their symptoms. The research is published in the journal Contact Lens and Anterior Eye.

In a study published in Advanced Science, researchers from the Institute of Biophysics of the Chinese Academy of Sciences, along with collaborators at the Institutes of Brain Science and Fudan University, have developed an innovative augmented reality (AR) training method that significantly improves visual function in adults with amblyopia.

Using pilocarpine eye drops following Kahook Dual Blade (KDB) goniotomy surgery may improve clinical outcomes for patients with glaucoma and reduce the need for future medications, according to new research published by faculty members and trainees in the Department of Ophthalmology at the University of Colorado School of Medicine. The study is published in the journal Current Eye Research.

A five-year clinical study has revealed that spectacle lenses equipped with highly aspherical lenslets (HAL) can significantly slow the progression of myopia and axial elongation in children. The findings are published in the journal Eye and Vision.

The prevalence and severity of refractive astigmatism and corneal astigmatism increased among schoolchildren after the COVID-19 pandemic, according to a study published online March 20 in JAMA Ophthalmology.
