  • Medically able to undergo vitrectomy and subretinal injection, a surgery which may require general anesthesia.
  • Good general health as defined by:
  • Normal serum chemistry and hematology. Out of normal range laboratory findings deemed not clinical significant are acceptable.

  • Males must be willing to use barrier and spermicide contraception during the study.
  • Ability to give written informed consent as evidenced by signature on the patient consent form, to communicate well with the investigator and to comply with the expectations of the study.

Exclusion Criteria:

  • The presence of ocular disease or ocular media opacity, which in the opinion of the investigator, precludes accurate evaluation during the study.
  • Prior vitrectomy in the study eye
  • Patients with a history of amblyopia will be excluded
  • High myopia (>6 diopters) in the study eye
  • Cataract surgery in the study within 3 months
  • Participation within 6 months in any clinical trial involving a drug or device treatment
