An Expanded Clinical Study Evaluating the AAV2-RPE65 Gene Therapy(LX101) in Patients With LCA

Exclusion Criteria

• •Have any of the following eye conditions:
• •1. Subjects with SAE in the "Exploratory clinical Study Evaluating AAV2-RPE65 gene therapy agent (LX101) in patients with congenital Amaurosis (LCA)
• •2. pre-existing eye conditions (such as glaucoma, cornea, or severe lens opacity) that the investigator determines may interfere with planned surgery or with interpretation of the study endpoint;
• •3. Screening subjects who had undergone any internal eye surgery in the six months prior to the visit;

• •Have any of the following systemic conditions:

For example, the treatment of malignant tumors can affect central nervous system function (e.g., orbital radiation therapy; Leukemia with central/optic nerve involvement); 10) Subjects with a history of immune-damaging diseases due to the possibility of opportunistic infection (e.g., CMV retinitis); Subjects with diabetes or sickle cell disease will be excluded if they have any manifestations of advanced retinopathy, such as macular edema or proliferative changes. Subjects with juvenile rheumatoid arthritis have an increased risk of infection due to poor postoperative wound healing; 11) Participants who cannot discontinue Viagra (Sildenafil) or related compounds used to treat erectile dysfunction during the study period; 12) Subjects who cannot discontinue hydroxychloroquine, Chloroquine, meralide, or any related retinal toxic compound during the study; 13) Any other conditions in which the potential subject is not allowed to complete a follow-up examination during the study, and the investigator believes that there are conditions that make the potential subject unfit for the study.
• •Fertile subjects with any of the following conditions:
