Short-term assessment of photoreceptor rescue after gene therapy

Leber congenital amaurosis (LCA) has been the first inherited retinal disease with a gene therapy approved for clinical use. An article recently published in Acta Ophthalmologica reports on the short-term effects of this therapy.

The authors, a team led by Katarina Stingl at University of Tübingen, used an rtx1 adaptive optics camera to assess changes at the level of photoreceptor cells in the retina of a LCA patient after treatment.

“This case demonstrates a remarkable fast restoration of the central photoreceptors within only 5 weeks after treatment as documented by high-resolution imaging. The effect was still visible after 3 months.”

Changes in the photoreceptor mosaic were observed several weeks before an improvement in visual acuity could be measured.
