Abstract
Intravitreal Bevacizumab (Avastin) and Ranibizumab (Patizra) both are vascular endothelial growth factor(VEGF) inhibitors that are developed against vascular endothelial growth factor isoforms which is the driving force behind ischemic neo vascularization in diabetic eye disease. The objective of our study is to evaluate the efficacy of pre-operative intravitreal Bevacizumab Vs Intravitreal Ranibizumab on post operative vitreous cavity bleed after three port 23 gauge pars-plana vitrectomy (PPV).
Patients & Methods
This study was conducted in the department of Ophthalmology Services Hospital Lahore from January 2024 to June 2024.Fourty (40) patients with advance diabetic eye disease were included in this study for three port 23 gauge pars plana vitrectomy (PPV) with pre operative intravitreal Bevacizumab or Avastin(1.25 mg/0.05 ml) and Intravitreal Ranibizumab one week prior to PPV and incidence as well as severity of post operative vitreous cavity bleeding was recorded on day one, day three and day seven along with severity grading from no visible bleed to mild and severe based on fundus examination .
Results
Mean patient age in our study was 57.36±3.62 years . Out of 20 eyes with pre operative intravitreal Bevacizumab , 15 patients (75%) had no bleeding, 3 (15%) were documented as mild and 2(10%) were documented ashaving severe post operative vitreous cavity bleed whrereas in the pre operative intravitreal Ranibizumab group out of 20 eyes , 16(80%) had no bleeding , 3(15%) had mild to moderate bleeding and 1(5%) were documented as severe post operative vitreous cavity bleeding in post operative followups.
Conclusion
Intravitreal Bevacizumab and Ranibizumab administered preoperatively to patients undergoing PPV for advance diabetic eye disease were found to be equally effective in minimizing post operative vitreous bleed in patients with ADED.
