Twelve patients are in the middle of a first-of-its-kind trial in the UK. They are undergoing gene therapy to correct a genetic gene deficiency; a gene called RPE65. It is supposed to be expressed at the beack of the eye, in the retina, and without that gene expression the eye won’t interpret images.
Currently in one patient, Robert Johnson, he can now see outlines during the day, but little at night – he has had genes inserted into one eye. The procedure itself requires extensive precision, including a risk of tearing the retina. (See image to the right; Source: Moorfields Eye Hospital)
