  12. In the Investigator's opinion, any severe acute or chronic medical condition, psychiatric condition, physical examination finding or laboratory abnormality
  13. Pre-existing conditions in the study eye such as glaucoma, diseases affecting the optic nerve causing significant visual field loss, history of uveitis, corneal or lenticular opacities).
  14. Presence of any complicating systemic diseases such as malignancies whose treatment could affect central nervous system function..
  15. Subjects who are positive for syphilis, hepatitis B, C, and human immunodeficiency virus (HIV) will be excluded..
  16. Presence of narrow iridocorneal angles contraindicating pupillary dilation in the study eye.
  17. Presence of disorders of the ocular media in the study eye which could interfere with visual acuity and other ocular assessments, including OCT, during the study period.
  18. Presence of macular hole in the study eye, evident by ophthalmoscopy and/or by OCT examinations
  19. Current evidence of retinal detachment in the study eye assessed by the Investigator that significantly affects central vision.
  20. Current use of hydroxychloroquine, chloroquine, or any related retina-toxic compounds.

Brief Summary
The purpose of the study is to evaluate the safety and effects of a single intravitreal injection of virally-carried Multi-Characteristic Opsin (vMCO-010) in Subjects with Stargardt Disease
Detailed Description
This multicenter open label study will evaluate single dose level of vMCO-010 in up to 6 subjects with Stargardt's Disease. Subjects with documented clinical diagnosis of Stargardt disease (classic fleck phenotype and/or well-demarcated sub-foveal area of significantly reduced autofluorescence as imaged by FAF), or genetic diagnosis with pathogenic variants in ABCA4, ELOVL4, or PROM 1. All subjects will continue to be assessed for 48 weeks following treatment with vMCO-010.
