Kate Garraway reveals cause of mystery eye condition was part of a contact lens that had been stuck in her eye for six days

  Kate Garraway reveals cause of mystery eye condition was part of a contact lens that had been stuck in her eye for six days Kate Garraway has revealed the cause of her mystery eye injury was part of a six-day-old contact lens nurses discovered in the top of her eye. The GMB presenter, 53, had visited a specialist eye hospital after suffering from an unknown eye condition, which had forced her to switch her usual contact lenses for glasses. But the cause of the discomfort she had been feeling turned out to be a small piece of contact lens that had got lodged in her eye and had been stuck there for six days.Revealing the unusual ailment to co-host Ben Shephard, the presenter explained that the discovery was made after a team of eye nurses had given her eye numbing drops and examined her eye.

An effective new treatment to restore vision is on the horizon that works by injecting genetically modified stem cells into the eye to mend the damaged retina.

Researchers found that the cells of damaged retinas send out a rescue signal to attract the stem cells that repair eye damage.

They identified two of these cell signals – known as Ccr5 and Cxcr6 – and then genetically engineered the stem cells to make them more sensitive to those signals.

  Drug tricks cancer cells by impersonating a virus The drug has been tested in mice and a small group of human patients.The drug, called BO-112, is in human trials and mimics the structure of a double-stranded RNA molecule, a type of genetic material found in some viruses. Viruses inject their RNA into cells during infection, but cells can spot this viral RNA using specific receptors, and call upon the immune system to intervene when viruses strike.

Getting regular eye checkups is just one of many ways you can get better eyesight . It’s a condition in which the macula — the part of the eye that controls central vision — deteriorates. Food sources for these important nutrients include a variety of colorful vegetables and fruits, such as

When these modified stem cells were transplanted back into mice and human tissue samples in the lab they flocked to the retina cells in much greater numbers, keeping the tissue of the damaged retina alive and functioning.

May one day cure blindness

The technique holds promise for improving sight in people with poor vision – and potentially even to cure blindness altogether – but the researchers cautioned that any such development was some years away and required much bigger studies to confirm their findings.

“One of the main hurdles in using stem cells to treat damaged eyesight is low cell migration and integration in the retina,” says Pia Cosma, at the Centre for Genomic Regulation in Barcelona.

“After the cells are transplanted they need to reach the retina and integrate through its layers. Here we have found a way to enhance this process using stem cells commonly found in the bone marrow, but in principle can be used with any transplanted cells,” Dr Cosma said.

Transplants feasible

“There is still considerable work to be done, but our findings could make stem cell transplants a feasible and realistic option for treating visual impairment and restoring eyesight,” she said.

Retinal damage, which is currently incurable, inevitably leads to visual disabilities and in most cases blindness. With a growing and ageing population, the number of people affected by retinal damage is estimated to increase dramatically over the next few decades.

Stem cell therapies have been touted as one way of treating degenerative retinal conditions. Stem cells can be transplanted into the eye, releasing therapeutic molecules with neuroprotective and anti-inflammatory properties that promote the survival, proliferation and self-repair of retinal cells. The stem cells can also generate new retinal cells, replacing lost or damaged ones.

Bone marrow cells

The researchers used mesenchymal stem cells, which are found in bone marrow and can differentiate into lots of types of cells, including retinal cells that respond to light.

Mesenchymal stem cells can also be easily grown outside an organism, providing abundant starting material for transplantation compared to other cell sources such as hematopoietic stem cells.

The study is published in the journal Molecular Therapy.
