Eligibility criteria

Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.

Inclusion Criteria:

* Male at least 18 years of age diagnosed with CHM gene mutation
* Central visual field (VF) \<30° in any of the 24 meridians (using Goldmann perimetry III4e isopter) in the eye to be injected
* Any evidence of functioning outer retinal cells within the central 10°

Exclusion Criteria:

* Previous history of ocular inflammatory disease (uveitis)
* Prior intraocular surgery within six months
* Participation in a previous gene therapy research trial within one year of enrollment or participation in any other ocular gene therapy trial
* Participation in a clinical study with an investigational drug in the past six months
* Grossly asymmetrical disease, or other eye morbidity, which may render the contralateral eye ineffective as a control
* Visual acuity \<20/200 on standard Early Treatment of Diabetic Retinopathy Study (ETDRS) testing in the eye to be injected
* Presence of disease which may preclude the participant from participation in this trial
* Use of medications known to be neuroprotective or retino-toxic that could potentially interfere with the disease process and/or cause ocular adverse events; individuals who discontinue use of these compounds for 6 months may become eligible
* Identification by the investigator as being unable or unwilling to perform/be compliant with study procedures.
