Let There Be Light: laser therapy for combating blindness

Karen Peynshaert, PhD

Posdoctoral researcher. Ghent University. (Belgium)

23 May 2024 10:00–10:30


The inner limiting membrane (ILM) is the dominant hurdle to overcome to reach the retina after intravitreal injection for both viral and non-viral carriers. Several strategies to remove this membrane have been investigated, yet all of them are invasive and/or toxic. In this lecture, we present a novel technology to manipulate the ILM by applying pulsed laser light. Indeed, our ex vivo and in vivo proof-of-concept studies have revealed that this strategy can greatly enhance the delivery of gene carriers to the retina following intravitreal injection.


Karen Peynshaert is a postdoctoral fellow at Ghent University with expertise in ocular drug delivery barriers. During her PhD she developed an ex vivo model, a vitreoretinal explant, designed to look at the vitreous and inner limiting membrane as barriers to retinal delivery. Her primary focus now is ILM photodisruption, a technology to manipulate the ILM, in context of delivery of AAVs, nanoparticles and since 2022 also stem-cell derived retinal ganglion cells.
