Eligibility
Inclusion criteria
Inclusion criteria: 1. Age >= 18 years 2. Diagnosis of diabetes mellitus (type 1 or type 2). 3. Vitreous haemorrhage (VH) in a patient with Proliferative Diabetic Retinopathy (PDR) causing vision impairment of duration less than one month, for which intervention is deemed necessary. 4. Patients who are willing and able to undergo vitrectomy within 2 weeks of presentation. 5. Visual acuity ranging between PL and ETDRS logMAR 0.3 (Snellenâ??s equivalent of 20/40 or 6/12).
Exclusion criteria
Exclusion criteria: 1. Any condition that precludes the participant from undergoing elective vitrectomy surgery in the study(e.g., unstable medical status including chronic renal failure requiring dialysis, blood pressure > 180/110, cardiovascular disease, pregnancy or lactation). 2. Systemic anti-VEGF or pro-vascular endothelial growth factor treatment within 4 months, intravitreal anti-VEGF in the study eye within 2 months of current vitreous haemorrhage onset, or intraocular corticosteroid treatment in the study eye within 4 months of current vitreous haemorrhage onset. 3. Participation in an investigational trial within 30 days that involves any drug that has not received regulatory approval for the indication being studied. 4. Potential participant is expected to lose follow-ups due to various reasons. 5. Evidence of traction or rhegmatogenous retinal detachment involving or threatening the macula. If the density of the haemorrhage precludes a visual assessment on the clinical exam to confirm eligibility, then it is recommended that the assessment be performed with ultrasound as standard care. 6. Evidence of uncontrolled glaucoma. 7. History of major ocular surgery (including vitrectomy, cataract extraction, scleral buckle, any intraocular surgery, YAG capsulotomy etc.) within 4 months or major ocular surgery other than vitrectomy anticipated within the next 6 months in the study eye. 8. Aphakia. 9. The evidence of severe external ocular infection, including conjunctivitis, chalazion, or substantial blepharitis.
