abstract = {To assess the safety and feasibility of direct
vitrectomy-sparing subretinal injection for gene delivery in
a large animal model.The experimental Liběchov minipigs
were used for subretinal delivery of a plasmid DNA vector
(pS/MAR-CMV-copGFP) with cytomegalovirus (CMV) promoter,
green fluorescent protein (GFP) reporter (copGFP) and a
scaffold/matrix attachment region (S/MAR) sequence. The eyes
were randomized to subretinal injection of the vector
following pars plana vitrectomy (control group) or a direct
injection without prior vitrectomy surgery (experimental
group). Intra- and post-operative observations up to 30 days
after surgery were compared.Six eyes of three mini-pigs
underwent surgery for delivery into the subretinal space.
Two eyes in the control group were operated with a classical
approach (lens-sparing vitrectomy and posterior hyaloid
detachment). The other four eyes in the experimental group
were injected directly with a subretinal cannula without
vitrectomy surgery. No adverse events, such as
endophthalmitis, retinal detachment and intraocular pressure
elevation were observed post-operatively. The eyes in the
experimental group had both shorter surgical time and
recovery while achieving the same surgical goal.This pilot
study demonstrates that successful subretinal delivery of
gene therapy vectors is achievable using a direct injection
without prior vitrectomy surgery.},
