Eligibility Criteria
Inclusion
- Patients with vitreomacular traction maculopathy for whom vitrectomy is indicated, according to the principal investigator, including:

- Stage II-III macular hole of \< 6 months duration since symptom onset;
- Demonstration of vitreomacular adhesion (based on preoperative optic coherence tomography \[OCT\]) in the study eye;
- OCT - presence of posterior hyaloid membrane inserting on to the macula, but with some area of clear separation visible between the retina and the posterior hyaloid.
Exclusion
- Evidence of fibrocellular proliferation characterized by whitish epimacular tissue (surface wrinkling is not an exclusion criterion).
- Patients with vitreous hemorrhage which precludes either of the following: visualization of the posterior pole by visual inspection OR adequate assessment of the macula by either OCT and/or fluorescein angiogram in the study eye.
- Patients with rhegmatogenous retinal detachment, proliferative vitreoretinopathy (PVR), or retinal degenerative changes in the study eye.
- Patients with high myopia or aphakia in the study eye
- Patients with history of rhegmatogenous retinal detachment in the fellow eye or family history of retinal detachment
- Patients who are considered likely to require intraocular surgery in the study eye for any reason other than vitreomacular traction maculopathy/macular edema in the coming three months.
- Patients who have had ocular surgery in the study eye in the prior three months.
- Patients who have had a vitrectomy in the study eye at any time.
- Patients with a history of uveitis or significant trauma in the study eye.

- Patients who, in the investigator's view, will not complete all visits and investigations, including the exit visit at 6 months.
- Patients who have participated in an investigational drug study within the past 30 days.
- HgA1c \> 9%.
- Patients with hypertension (either systolic blood pressure \[SBP\] \> 170 or diastolic blood pressure \[DBP\] \> 100 mm Hg).
- Patients with a life-expectancy less than 6 months.
