Name Time Method Main Objective: To evaluate the long-term safety and efficacy of a sub retinal injection of:<br>• AAV2-REP1 in participants with CHM who have been previously treated with AAV2-REP1 and who have exited an antecedent study; these treated participants will be compared with untreated control participants who have exited the STAR study.<br>• AAV8-RPGR in participants with XLRP who have been previously treated with AAV8-RPGR and who have exited an antecedent study.;Secondary Objective: Not applicable;Primary end point(s): The primary endpoint of this study is safety of AAV2-REP1 and AAV8-RPGR, which will be evaluated through adverse event (AE) reporting and full ophthalmic examinations.<br>Datasets from the 2 disease populations will be analyzed separately. ;Timepoint(s) of evaluation of this end point: Safety assessments will be performed as per protocol
