EyeConic: Qualification for Cone-Optogenetics
December 6, 2023 updated by: University Hospital, Basel, Switzerland
Qualification for Cone-Optogenetics (EyeConic)
This study aims to prepare for the first-in-human clinical trial of cone optogenetics vision restoration.
As a first step, this worldwide multicenter ocular imaging study (EyeConic Study) is performed to identify eligible patients.
Study Overview
Detailed Description
In a subset of patients with inherited retinal dystrophies (IRDs), cones lose their light-sensitive outer segments but remain alive in a dormant stage.
This creates an opportunity to resensitize them through targeted optogenetic tools.
However, the true proportion of low vision patients harboring dormant, non-functional cones, is currently unknown.
The worldwide multicenter retrospective study (EyeConic) aims to estimate the proportion of low vision patients with remaining cone cell bodies for the first time.
