This is a phase I/II open label, randomized, interventional clinical trial. Study eyes will receive one preoperative intravitreal aflibercept injection (IAI) <21 days but >7 days prior to vitrectomy and one intraoperative IAI at end of surgery followed by randomization in a 1:1 ratio into either 4 mandatory postoperative q4weeks IAI followed by mandatory q8 weeks IAI for 52 weeks follow-up (q8 week Group) or 2 mandatory postoperative q4weeks IAI followed by mandatory q16 weeks IAI for 52 weeks follow-up (q16 week Group).

Follow-up visits occur 1 day and 1-2 weeks, and 4 weeks postoperatively and then every 4 weeks from the first postoperative IAI for 52 weeks. One preoperative visit and every postoperative visit (except day one postoperatively) will include ETDRS Best Corrected Visual Acuity (BCVA), Intraocular Pressure (IOP) measurement, Slit lamp biomicroscopy, Indirect ophthalmoscopy, Heidelberg Spectralis Spectral Domain Optical Coherence Tomography (SD-OCT) (no OCT for preoperative visit) and evaluation for systemic and ocular adverse events. Seven standard field photographs and Optos wide-field fluorescein angiography will be performed at postoperative visits at 4, 16, 28, 40,and 52 weeks. Humphrey visual field (HVF) testing (30-2 and 60-4 test patterns) will be performed at postoperative visits at 4 and 52 weeks. Preoperative B scan echography will be required standard of care(SOC) to assess for macular traction, non-macular traction, retinal detachment and vitreous hemorrhage(VH). Identification of traction macular detachment will exclude the patient from the study.

Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma.
A drug used to reduce hemorrhage in diabetic retinopathy.
Disease of the RETINA as a complication of DIABETES MELLITUS. It is characterized by the progressive microvascular complications, such as ANEURYSM, interretinal EDEMA, and intraocular PATHOLOGIC NEOVASCULARIZATION.
Vision considered to be inferior to normal vision as represented by accepted standards of acuity, field of vision, or motility. Low vision generally refers to visual disorders that are caused by diseases that cannot be corrected by refraction (e.g., MACULAR DEGENERATION; RETINITIS PIGMENTOSA; DIABETIC RETINOPATHY, etc.).
Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.
