Scientists discover gene responsible for rare, inherited eye disease

Scientists at the National Institutes of Health (NIH) and their colleagues have identified a gene responsible for some inherited retinal diseases (IRDs), which are a group of disorders that damage the eye's light-sensing ...

Case series offers insights on corneal epithelial ingrowth after small incision lenticule extraction surgery

Corneal epithelial ingrowth (EI) is a rare but significant complication following small incision lenticule extraction (SMILE) surgery. Although this refractive procedure offers several advantages, such as a smaller incision ...

Immunology

Researchers discover new role of immune cells in eye health

The eye is an immune-privileged tissue because of the need to keep blood vessels away from the central pathway of light and to restrict entry of inflammatory cells that could cause damage. This has prompted questions about ...

Your eyes could reveal the first signs of many diseases

Melissa, a 30-year-old educator, came to the emergency department with a sudden onset of double vision. She had not been in an accident or suffered any trauma and had never experienced this symptom before. However, she noted ...

100-fold improvement in sight seen after gene therapy trial

The vision of people with a rare inherited condition that causes them to lose much of their sight early in childhood was 100 times better after they received gene therapy to address the genetic mutation causing it. Some patients ...

Understanding Graves' disease

Graves' disease is a condition of the immune system that leads to an overactive thyroid. It is caused by antibodies attacking the thyroid by mistake. The thyroid and the hormones it produces are the gas pedal for the body. ...

New research sheds light on vision loss in Batten disease

Progressive vision loss, and eventually blindness, are the hallmarks of juvenile neuronal ceroid lipofuscinosis (JNCL) or CLN3-Batten disease. New research shows how the mutation associated with the disease could potentially ...

The benefits of reading outdoors

Contrast is a sensory property that makes stimuli stand out. Writers, designers, and musicians all use contrast to emphasize striking differences in text, visual displays and melodies. In vision, luminance contrast describes ...

Generation of conjunctivae in a dish

Conjunctival tissue is perhaps most recognizable to the average person in relation to conjunctivitis—but it's a vital part of the eye's functionality and protection. In a new study, researchers from Osaka University generated ...
