Learning curve of a trained vitreo-retinal surgeon in sub-retinal injections in a rat model: Implications for future clinical trials.

Purpose: The sub-retinal injections are not very commonly performed procedures in vitreoretina, but form a crucial step in any cell replacement therapy for retinal diseases. The purpose of this study is to describe the learning curve of a trained vitreo-retinal surgeon in sub-retinal injections in a rat model and its implications in future clinical trials.

Methods: This is an in-vivo retrospective animal study using Wistar rats.
