Inherited retinal dystrophies (IRD) have been studied since their recognition by Franz
Donders and Albrecht von Graefe. It nevertheless took 100 years for a causal therapy
to take shape in the form of gene therapy: The approval of Voretigen Neparvovec (VN)
for the treatment of hereditary retinal dystrophies due to RPE65 mutations was thus a significant milestone – for the era of personalised medicine
in general and ophthalmology in particular. The clinical management around gene therapy
applications is complex and requires the cooperation of various experts as a multidisciplinary
team. This article describes the requirements, challenges, approaches, and open questions
regarding the surgical aspects of gene therapy for retinal dystrophies. The first
part outlines the standard surgical treatment. Based on this standard, alternative
approaches are indicated for each individual step and their value discussed. Knowledge
gaps are defined and in the outlook we speculate
on future developments.
