Low-Cost OCT Retinal Scanner Could Help Prevent Blindness Worldwide

Biomedical engineers at Duke University have developed a low-cost, portable optical coherence tomography (OCT) scanner that promises to bring the vision-saving technology to underserved regions throughout the United States and abroad.

Thanks to a redesigned, 3D-printed spectrometer, the scanner is 15 times lighter and smaller than current commercial systems and is made from parts costing less than a tenth the retail price of commercial systems—all without sacrificing imaging quality.

U.S. District Judge Ursula Ungaro of the Southern District of Florida has issued an order that stops US Stem Cell Clinic LLC, of Weston, Florida, and US Stem Cell Inc., of Sunrise, Florida, and their Chief Scientific Officer Kristin Comella, Ph.D., from manufacturing or distributing any and all stromal vascular fraction (SVF) products, which are adipose (fat) tissue derived stem cell products, until they come into compliance with the law.

Immune system may slow degenerative eye disease

A new study shows that the complement system, part of the innate immune system, plays a protective role to slow retinal degeneration in a mouse model of retinitis pigmentosa, an inherited eye disease. This surprising discovery contradicts previous studies of other eye diseases suggesting that the complement system worsens retinal degeneration. 

The research was performed by scientists at the National Eye Institute (NEI), part of the National Institutes of Health, and appears in the Journal of Experimental Medicine.
