Gene that regulates immune activity in the retina identified
UT Southwestern Medical Center

UT Southwestern Medical Center researchers have identified a gene called Lipe that appears to be pivotal to retinal health, with mutations spurring immune activation and retinal degeneration. This is important because the retina is responsible for detecting the light that is transformed into vision. The findings, published in Communications Biology, provide clues about the mechanisms behind a variety of disorders affecting the retina, including macular degeneration and diabetic retinopathy.

Questions remain about artificial tears linked to an outbreak of Pseudomonas aeruginosa infections involving 64 people in 13 states, including 8 cases of vision loss, as well as lung and urinary tract infections, and one death. Federal agencies warned people to stop using EzriCare and Delsam Pharma artificial tears after tests of opened bottles used by those affected found a rare, extensively drug-resistant strain of P. aeruginosa. The strain had never been reported in the United States.What is clear is that eye health experts have advice for people using artificial tears, which are sold over the counter and widely used for eye irritation associated with dry eye disease, contact lens use, and refractive surgery, as well among those using other eye drops regularly, such as for glaucoma.
