To the Editor: Leber's congenital amaurosis, a common cause of blindness in infants and
children, 1 recently became the first human genetic retinal disease to show improved vision
in response to treatment. Patients with mutations in the gene encoding retinal pigment
epithelium–specific 65-kD protein (RPE65) had gains in vision within weeks after subretinal
injection of a vector containing the gene in one eye. 2–5 At 1-year follow-up after gene

Patients with mutations in the gene encoding retinal pigment epithelium–specific 65-kD protein (RPE65) had gains in vision within weeks after subretinal injection of a vector containing the gene in one eye.25 At 1-year follow-up after gene therapy, the three young adult patients in our trial4,5 remained without serious adverse events.
A noteworthy observation in one patient at 1 year after treatment prompted further studies. For . . .
