Brief summary
The goal of this clinical trial is to evaluate the safety and early effectiveness of ZVS101e in patients with Bietti crystalline dystrophy who meet the eligibility criteria for treatment under the translational application program in the Hainan Boao Lecheng International Medical Tourism Pilot Zone. Participants will: undergo screening and baseline assessments to confirm eligibility; receive a single subretinal injection of ZVS101e in the study eye; complete follow-up visits over 4 weeks after treatment for safety monitoring and assessment of early effectiveness.
Interventions
ZVS101e injection contains a recombinant adeno-associated virus serotype 8 (rAAV8) vector that expresses human CYP4V2 protein.
