Full description

Protocol available upon request.

Enrollment: 24 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

8. Intraocular surgery (including cataract surgery) in the study eye within 60 days preceding baseline.
9. History of vitrectomy surgery in the study eye.
10. Subjects with 12 or more anti-VEGF injections within 24 months prior to Screening.
