Interventions
Intravitreal bevacizumab or intravitreal ziv-aflibercept is given preoperatively at various time intervals and doses.
Eligibility Criteria
You may qualify if:
- Subject age is 18-85 years.
- Subject consents to study participation and is capable of 6 months of follow-up.
- The subject has type I or II Diabetes Mellitus with active PDR in the study eye.
- Best-corrected spectacle visual acuity (BCSVA) on the Snellen eye chart ranges from 20/40 to light perception with projection in the study eye.
- The subject is determined to need a PPV because of reduced BCSVA principally from a non-clearing vitreous hemorrhage, TRD, fibrous proliferation, or a combination of the three. When non-clearing vitreous hemorrhage is the principal reason for PPV, the hemorrhage must have been present by subjective history for at least 3 months. When TRD is the principal reason for PPV, the TRD must be threatening (within one disc diameter) or involving the fovea. When fibrovascular proliferation is the principal reason for PPV, it must be extensive (\>3 clock hours) and threatening (within one disc diameter) or involving the fovea.
- Only one eye per patient is eligible for the study.
You may not qualify if:
- Subject is known to have a significant retinal/optic nerve disease otherwise unrelated to Diabetes Mellitus, which in the opinion of the examiner is responsible for two or more lines of reduced BCSVA (macular degeneration, optic neuritis, glaucoma, amblyopia, etc.) in the study eye.
- Subject is known to have macular ischemia, which in the opinion of the examiner, is responsible for two or more lines of reduced BCSVA in the study eye.
- Subject has a significant corneal opacity, which in the opinion of the examiner, is responsible for two or more lines of reduced BCSVA (corneal scar, ectasia, etc.) in the study eye.
- Subject is known to have had a macula-involving retinal detachment for greater than 6 months in the study eye.
- Subject has had a previous vitrectomy (anterior or PPV) in the study eye.
- Subject has uncontrolled neovascular glaucoma (intraocular pressure \> 30 mmHg despite medical/surgical treatment) in the study eye.
- Subject received systemic or intravitreal anti-VEGF treatment to the study eye within 3 months of anticipated study enrollment.
- Subject has uncontrolled hypertension (systolic \> 200 mmHg or diastolic \> 120 mmHg) despite adherence to a multiple anti-hypertensive medication regimen.
