Eye surgery boost for gene therapy patients

Eye surgery
Eye surgery to treat patients with impaired vision since birth is often aided by the brain's ability to re-wire itself so that it can recognise the parts of the retina being replaced.

Surgeons administering gene therapy to restore sight have found that enough image-processing strength is exposed to the treated retina sections to enable connection to the fovea.

Through this process the eye is then able to capture the brain's attention and function normally.

Dr William Hauswirth, professor in the ophthalmology department at the UF College of Medicine, commented: "When one patient came back for her 12-month visit, she said she could read the digital clock in her parents' car with her treated eye - something she was never able to do before.

"That prompted us to measure where her gaze was fixed while looking at a variety of dim targets. This showed that she now has two preferred centres of vision rather than one, depending on the brightness of the object."

A recent study has found that medicated eye drops could reverse the symptoms of glaucoma.
