Purpose : Within the recent year’s nucleic acid-based therapeutics have gained a lot of interest for the treatment of ophthalmic pathologies.

Methods : Despite some success of small RNAi based approaches the delivery to the posterior eye segment still remains a major obstacle, especially for larger mRNA. For direct intravitreal injection of nanoparticles the vitreous can interfere with the diffusion of nanoparticles and can prevent reaching the relevant cells.

Results : Here we report a novel polymeric carrier system (CVCMs) that enables the delivery of mRNA by intravitreal and sub-retinal injection to the rat eye. After intravitreal injection of CVCM-encapsulated mRNA, encoding reporter protein, protein expression was detected in eye tissue lysates. After sub-retinal injection of the CVCM encapsulated mRNA the reporter protein expression was localized in the photoreceptor inner segment which is an attractive target tissue for therapeutic intervention.

Conclusions : Overall the CVCM based polymeric delivery system allows for ocular delivery of mRNA and will be utilized to develop therapeutic application in the near future.
