Subjects undergoing optical coherence tomography (OCT) and fundus imaging must have adequate pupillary dilatation and clear media to perform imaging studies including fundus fluorescein angiography. 5. Subject must have a clinical indication for vitrectomy based on a diagnosis of one of the following conditions: vitreoretinal traction, asteroid hyalosis, macular pucker/epiretinal membrane, macular hole, or vitreous hemorrhage 6. Subject must have uncorrected visual acuity worse than 20/40 (Snellen) at Visit 1
Exclusion criteria
Exclusion criteria: The patients will be excluded from the study based on the following exclusion criteria: 1. Subjects who have participated in any drug or device clinical investigation within 30 days prior to entry into this study and/or will participate in another investigation during the period of study participation. 2. Subjects with retinal disorders in the study eye that may confound interpretation of or prevent obtaining fundus fluorescein angiography (FA) or OCT images, including retinal vascular occlusion, choroidal neovascularization, macular atrophy or scarring, ocular histoplasmosis, or pathologic myopia. 3. Subjects who have had prior vitrectomy surgery, cryopexy, or retinal buckle procedure. 4. Subjects with prior history of retinal tear, vitreoretinal tractional detachment, or ocular tumors in either eye. 5. Subjects with visual acuity of No Light Perception at Visit 1. 6. Female subjects of child-bearing potential who have a positive urine test for pregnancy at Visit 1. 7. Subjects who have experienced any significant trauma in the operative eye within the past month. 8. Subjects with any active ocular infection or history of any herpetic infection that has cleared less than one month prior to the pre-operative visit. 9. Subjects with history of complicated cataract surgery involving vitreous loss or a history of vitreoretinal surgery in the study eye. 10. Subjects with uncontrolled glaucoma or ocular hypertension (IOP > 24 mmHg) in the operative eye. 11. Subjects with dislocated lens or retained lens fragments. 12. Subjects with a known bleeding disorder or using drugs known to increase the likelihood of bleeding. 13. Subjects with uveitis refractory to treatment. 14. Subjects with significant anterior segment abnormality that would interfere with visualization of the vitreous or retina. 15. Subjects with a known allergy to sodium fluorescein dye. 16. Subjects with any medical condition (e.g., uncontrolled diabetes) that, based on the Investigatorâ??s medical judgment, poses a concern for the subjectsâ?? safety.
