NEI-funded study explores methods to improve diagnosis, treatment of common eye diseases

If you've ever been sleep-deprived, you've probably had a firsthand glimpse of the blood vessels in your eyes. But what you haven't seen—and what many eye care professionals cannot see as well as they would like—are the vessels closest to the retina, the light-sensitive tissue at the back of the eye.

Optics Express publishes new paper on smart micromanipulation aided robotic-surgical tool

Even the most skilled and steady surgeons experience minute, almost imperceptible hand tremors when performing delicate tasks. Normally, these tiny motions are inconsequential, but for doctors specializing in fine-scale surgery, such as operating inside the human eye or repairing microscopic nerve fibers, freehand tremors can pose a serious risk for patients.

Advanced optics system noninvasively maps out network of tiny blood vessels beneath the skin

The trained eye of a dermatologist can identify many types of skin lesions, but human sight only goes so far. Now an international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients' skin, potentially revealing telltale signs of disease.
