What is HR-SD-OCT?
HR-SD-OCT stands for high resolution spectral-domain optical coherence tomography, a technique used for imaging the retina.
How does the subretinal injection procedure work?
The procedure involves using sterile forceps to gently induce proptosis and guide a needle for precise injection into the subretinal space.
What are the advantages of this method?
Advantages include minimal retinal damage, precise injection mapping, and the ability to conduct rigorous quantitative measurements.
Why is photoreceptor vitality assessment important?
Assessing photoreceptor vitality is crucial for determining the success of gene therapy and the health of retinal cells post-treatment.
Can this technique be used for other types of therapies?
While this study focuses on gene therapy, the method may have applications in other ocular therapies requiring precise delivery.
