Early Vitrectomy for Severe Vitreous Hemorrhage in Diabetic Retinopathy

Intravitreal Anti-Vascular Endothelial Growth Factor Agents for the Treatment of Diabetic Retinopathy: A Review of the Literature

“…In a pilot randomized double-masked study, intravitreal ranibizumab or saline (control) was used 7 days prior to PPV in patients with TRD associated with PDR. At month 3, there was no difference in the progression of TRD prior to surgery, the duration of surgery, or its technical difficulty between the two groups, although ranibizumab reduced the extent of post-operative vitreous cavity hemorrhage, while the study was underpowered to reveal a difference in visual outcome [64].…”

“…Furthermore, during PPV, visible vitreoretinal traction is generally removed along with vitreous scaffolding, preventing subsequent TRD [62,63]. The Diabetic Retinopathy Vitrectomy Study (DRVS) supported that there is a benefit of early vitrectomy in patients with type 1 diabetes, exhibiting severe VH, while the majority (80%) of patients with type 2 diabetes and severe VH still require a vitrectomy to resolve the VH after 1 year [64]. The results of PPV with current techniques seem to be better than in DRVS.…”

Early versus Late Pars Plana Vitrectomy in Vitreous Hemorrhage: A Systematic Review

“…Feman et al [17], in 1990, published the results of a randomized controlled trial (RCT) involving 616 eyes with severe diabetic VH comparing early vitrectomy and late PPV. In the early group, PPV was performed immediately, whereas in the late group, PPV was performed after 12 months from the diagnosis.…”

Developments in Non-Invasive Imaging to Guide Diagnosis and Treatment of Proliferative Diabetic Retinopathy: A Systematic Review

“…Seminal studies from the 1980s that established a gold-standard evidence base to inform management of DR include the Diabetic Retinopathy Study (DRS) [20], the Diabetic Retinopathy Vitrectomy Study (DRVS) [14,29], and the Early Treatment Diabetic Retinopathy Study (ETDRS) [21]. These early studies used 30-degree fundus cameras to image the posterior pole of the retina.…”
