Researchers have published preliminary results of a first-in-human clinical trial for dry age-related macular degeneration (AMD). Four patients received implants consisting of human embryonic stem cell-derived retinal pigment epithelium (RPE), which support light-sensitive photoreceptor cells critical to vision.
Watch your step: How vision leads locomotion

People with diabetes are twice as likely to develop cataract as the general population and the relative risk is highest in those aged between 45 and 54, according to a new study.
Substances found in cornea activate healing of blinding scar tissue

Two substances typically associated with brain neurons are involved in the healing process of the cornea in humans. The discovery suggests that the substances, which are produced naturally in the cornea, could form the basis for a non-invasive treatment of corneal opacity. This according to a doctoral dissertation published at Umeå University.
New eye pressure test could prevent vision loss in older adults

By age 75, approximately half of all Americans will develop cloudy vision caused by cataracts. The most common complication from cataract surgery is high eye pressure, which can cause swelling and other issues that can lead to vision loss or even blindness. Now, researchers recommend a new test to check eye pressure to prevent possible vision loss
Trigger for most common form of vision loss discovered

Researchers have discovered a critical trigger for the damaging inflammation that causes macular degeneration and ultimately robs millions of their sight. The finding may allow doctors to halt the inflammation early on, saving people from blindness.
Research shows new mechanism that can cause eye inflammation

Research presented at the ASM Microbe research meeting demonstrates a new way bacteria can cause dramatic morphological changes in human cells. Specifically, the researchers discovered that a common bacterial contaminant of contact lenses and cases can cause the formation of large bubble-like membrane structures on human ocular cells, which can contribute to contact lens wear complications and inflammation.
