Study reveals significant restoration of retinal and visual function following Gene Therapy

(c) Nature Biomedical Engg
A breakthrough study, led by researchers from the University of California, Irvine, has demonstrated restoration of retinal and visual functions of mice models suffering from inherited retinal disease.

Published today in Nature Biomedical Engineering, the paper, titled, “Restoration of visual function in adult mice with an inherited retinal disease via adenine base editing,” illustrates the use of a new generation CRISPR technology and lays the foundation for the development of a new therapeutic modality for a wide range of inherited ocular diseases caused by different gene mutations.

Is it possible for us humans to regenerate our eyes? Research points to a possibility.

Damage to the retina is the leading cause of blindness in humans, affecting millions of people around the world. Unfortunately, the retina is one of the few tissues we humans can't grow back. 

Unlike us, other animals such as zebrafish are able to regenerate this tissue that's so crucial to our power of sight. We share 70 percent of our genes with these tiny little zebrafish, and scientists have just discovered some of the shared genes include the ones that grant zebrafish the ability to grow back their retinas.

COVID-19 and the Retina - how does this Coronavirus affect the back of the eye?

(c) Wikipedia
COVID-19 can affect the retina. Retinal vein diameter seems directly correlated with the disease severity. Its assessment could have possible applications in the management of COVID-19.

As the coronavirus pandemic evolves and spreads worldwide, more information emerges on how the virus affects the body. What was once a respiratory illness has now become a systemic infection, affecting multiple organs.

AI Algorithm Helps Screen COVID-10 patients based on Eye Images

(c) Yanwei Fu
Scientists describe a potential screening method for COVID-19 based on eye images analyzed by artificial intelligence. Scanning a set of images from several hundred individuals with and without COVID-19, the tool accurately diagnosed coronavirus infections more than 90 percent of the time, the developers reported in a preprint posted to medRxiv September 10.

New OCT technique offers better potential in retinal stem cell and gene therapy treatment


Researchers at the University of Washington have modified the standard process of OCT (optical coherence tomography) to detect minute changes in response to light in individual photoreceptors in the living eye. The technique has potential in the testing of therapies such as stem cells or gene therapy to treat retinal disease.
