Cataract surgery in infancy increases glaucoma risk
Children who undergo cataract surgery as infants have a 22% risk of glaucoma 10 years later, whether or not they receive an intraocular lens implant. The findings come from the National Eye Institute (NEI)-funded Infant Aphakic Treatment Study, which today published 10-year follow-up results in JAMA Ophthalmology. NEI is part of the National Institutes of Health. (2020-12-17)

Study in mice shows genes may be altered through drug repurposing
Researchers screened drugs that can enhance the PAX6 gene and found MEK inhibitors can stimulate PAX6 expression in the eye. They tested this drug in newborn PAX6 deficient mice and found that either topical or oral administration of the drug enhanced PAX6 and partially normalized their eye development. Mice treated with topical MEK inhibitor had clearer corneas (less scarring) and could see better. (2020-12-17)

Drug for rare disorder shows promise for treating herpes viruses
New research shows that the antiviral activity of the drug -- called phenylbutyrate, or PBA -- was even better when used along with acyclovir, a common HSV-1 treatment. When used in combination, less acyclovir is needed to effectively suppress the virus compared to acyclovir alone -- this is important because acyclovir is also known to have toxic side effects in the kidneys. (2020-12-07)

Novel population of neurons identified that control binocular eye movements in 3D space
Researchers have discovered a previously undescribed population of neurons called saccade-vergence burst neurons that help control our eyes as they view in three-dimensional space. Models had predicted the existence of such neurons. The neurons are in a region of the mid-brain called the central mesencephalic reticular formation. (2020-11-11)

Cornea appears to resist infection from novel coronavirus
Some doctors have worried that the novel coronavirus may be able to infect people by getting into their eyes. Viruses such as herpes simplex can infect the eye's cornea and Zika virus has been found in corneal tissue and tears, but new research from Washington University School of Medicine in St. Louis suggests the cornea can resist infection from SARS-CoV-2. (2020-11-03)

Therapy using immune system cells preserves vision in mice implanted with rare eye cancer
A treatment that uses immune system T cells, combined with an immune-boosting drug packaged in an injectable gel, was found to preserve the vision of mice implanted with retinoblastoma tissue. The cancer, which is most commonly diagnosed in infants and young children, is treatable in early stages but can still lead to the loss of vision in about 5% of cases. (2020-10-12)

These results provide new knowledge in the endeavor to further improve healthcare for a large group of patients. (2020-10-02)

CU researcher: Outdated corneal donation policies prevent sight-restoring surgery
U.S. and Canadian restrictions on corneal donations prevented as many as 3,217 corneal donations from gay and bisexual men in 2018, despite a worldwide need for corneas for vision-restoring surgery and a lack of scientific evidence of harm caused by corneas from these men, according to a new study published in the September 24 issue of the journal JAMA Ophthalmology. (2020-09-24)

Researchers discover predictor of laser treatment success in patients with glaucoma
More than 70 million people worldwide suffer from glaucoma. Treatment options have traditionally included eye drops to reduce the fluid the eye produces or surgery to unclog the eye's drainage. But a new study from the University of Missouri School of Medicine and MU Health Care provides insight into which patients might benefit most from a noninvasive treatment called selective laser trabeculoplasty (SLT), which relieves pressure by using a laser to alter the eye tissue, resulting in better fluid drainage. (2020-08-05)
