Delayed healing linked to weaker electrical currents in diabetic wounds

People with diabetes often suffer from wounds that are slow to heal and can lead to ulcers, gangrene and amputation. New research from an international group led by Min Zhao, professor of ophthalmology and of dermatology at the University of California, Davis, shows that, in animal models of diabetes, slow healing is associated with weaker electrical currents in wounds.

Researcher employs high-resolution imaging, mechanical mapping to gauge structural integrity of cornea

A biomedical engineer at the University of Houston is developing new techniques to map the structural integrity of the human cornea, work that could lead to more effective therapies for degenerative corneal disease.

Controlling corneal blindness by 2030: an interview with Dr Pravin Vaddavalli

Corneal blindness is estimated to be the second most prevalent cause of blindness in many less developed countries. Globally, bilateral corneal blindness is estimated to afflict 4.9 million persons and accounts for 12% of 39 million blind, utilizing WHO 2010 global blindness data.

First limbal stem cell transplant performed in Ireland

On Tuesday 7th June 2016, the first Limbal Stem Cell transplant in Ireland was performed by Mr. William Power, Consultant Ophthalmologist at the Royal Victoria Eye and Ear Hospital in Dublin.

Vision Express advises Britons to be 'sun safe' when choosing eyewear

Britons are putting their sight at risk – potentially exposing themselves to cataracts and macular degeneration – by choosing vanity over UV protection when buying sunglasses, new research from Vision Express has revealed.

New light-based technique may offer improved treatment for eye problems

Researchers have developed a new light-based technique that selectively stiffens tissue in the cornea and might one day offer improved treatment for eye problems caused by weakened corneal tissue.

New methods for IOP measurements in patients with abnormal corneas

As a fundamental component of the ocular examination, accurate measurement of intra-ocular pressure (IOP) facilitates the management of patients with established glaucoma and the identification of patients with an elevated risk of developing glaucoma. For over 70 years, the most common method of measuring IOP has been by Goldmann Applanation Tonometry (GAT), largely on account of its low cost and ease of use.

Researchers discover gene that plays vital role in inherited eye disorder

Researchers from the University of Liverpool have identified a specific gene that plays a key role in an inherited eye disorder.

TKCI outlines plan to curb corneal blindness worldwide by 2030

The Tej Kohli Cornea Institute in partnership with the world-renowned LV Prasad Eye Institute, has today laid out its plan to control corneal blindness, globally, by 2030.

Scientists identify genetic mechanisms behind development of myopia

Myopia, also known as short-sightedness or near-sightedness, is the most common disorder affecting the eyesight and it is on the increase. The causes are both genetic and environmental.

Study: British adults agree to donate heart, kidney and lungs, but not eyes for transplant

Despite a shortage of corneas for transplant purposes, new research reveals that eyes are the one body part we are least likely to donate.

Investigators find tacrolimus to be very effective in reducing ocular symptoms of GVHD

Researchers from Massachusetts Eye and Ear/Harvard Medical School have conducted a clinical trial comparing the safety and efficacy of topical tacrolimus, an immunosuppressive therapy, and topical methylprednisolone, a steroid medication, in patients with ocular graft-versus-host-disease (GVHD) -- a complication associated with allogeneic bone marrow transplants in which the transplanted immune system's cells attack certain parts of the recipient's body, including the cornea and ocular surface.

Scientists reveal mechanism involved in regulation of lymphangiogenesis

After an injury to tissues, such as in organ transplantation, the body grows new lymphatic vessels in a process known as lymphangiogenesis. A new study in Nature Communications reveals a mechanism involved in the regulation of this process, specifically in corneal transplants and infectious eye disease.

Research suggests new pathway for preventing optic nerve damage in KPro recipients

Researchers from Massachusetts Eye and Ear/Harvard Medical School have identified inflammatory factors that cause optic neuropathy in the back of the eye following implantation of a keratoprosthesis (KPro) — similar to what glaucoma patients experience, without the rise of pressure in the eye — and have shown that blocking one of those factors, tumor necrosis factor alpha (TNFa), successfully halts the development of optic nerve damage in a mouse model.

UT Southwestern scientists discover mutation that causes X-linked reticulate pigmentary disorder

UT Southwestern Medical Center researchers have discovered a mutation that causes a rare systemic disorder known as X-linked reticulate pigmentary disorder (XLPDR) and, significantly, the unexpected cellular mechanism by which the mutation causes the disease.

Fish's retina inspired autofocus contact lens could benefit presbyopia patients

Making the most of the low light in the muddy rivers where it swims, the elephant nose fish survives by being able to spot predators amongst the muck with a uniquely shaped retina, the part of the eye that captures light. In a new study, researchers looked to the fish's retinal structure to inform the design of a contact lens that can adjust its focus.

Scientists demonstrate method for generating eye tissues to restore lost or damaged vision

Scientists have demonstrated a method for generating several key types of eye tissue from human stem cells in a way that mirrors whole eye development.

FDA allows marketing of one-time use contact lens to help measure patient's intraocular pressure

The U.S. Food and Drug Administration today allowed marketing of a one-time use contact lens that may help practitioners identify the best time of day to measure a patient's intraocular pressure (IOP). Elevated IOP is often associated with the optic nerve damage that is characteristic of glaucoma.

Researchers reveal link between mitochondrial dysfunction and Fuchs' Endothelial Corneal Dystrophy

Researchers at Schepens Eye Research Institute of Massachusetts Eye and Ear have shown a link between mitochondrial dysfunction in corneal endothelial cells and the development of Fuchs' Endothelial Corneal Dystrophy.

Diabetes researchers develop novel technique to monitor insulin resistance

Diabetes researchers at Sweden's Karolinska Institutet have developed a novel technique that makes it possible to monitor insulin resistance in a non-invasive manner over time in mice. The new method, presented in the journal Scientific Reports, can be used to assess insulin resistance during progression and intervention of metabolic diseases.
