Gene Therapy for Inherited Retinal Disease: Current Strategies, Personalized Medicine, and Future Implications-A...

Area of Science:

• Ophthalmology
• Genetics
• Molecular Biology

Background:

• Gene therapy is emerging as a revolutionary treatment for inherited and acquired retinal diseases.
• The eye's unique characteristics make it highly suitable for targeted gene therapy delivery.
• Current treatments often manage symptoms, whereas gene therapy addresses the genetic root cause.

Purpose of the Study:

• To explore the potential of gene therapy in ophthalmology.
• To highlight advancements in gene therapy for retinal diseases.
• To discuss the future prospects of gene-based treatments for vision restoration.

Main Methods:

• Introduction of exogenous genetic material to correct gene expression.
• Utilizing viral vectors for targeted delivery to retinal cells.
• Employing subretinal or intravitreal injection for localized treatment.

Main Results:

• The approval of voretigene neparvovec-rzyl demonstrated the efficacy and safety of gene replacement therapy.
• Gene therapy has shown potential in preserving or restoring vision in patients with specific genetic mutations.
• The eye's anatomical and immunological features facilitate effective gene therapy delivery.

Conclusions:

• Gene therapy represents a significant advancement in treating retinal diseases at their genetic origin.
• Future developments in vector design and gene editing will broaden therapeutic applications.
• The field is rapidly progressing, with numerous clinical trials indicating a future of more accessible and effective gene-based eye treatments.
