Vitrectomy

In Prolifertive Diabetic Retinopathy eyes with bleeding known as vitreous hemorrhage (VH) requiring a surgical procedure to remove the vitreous, called a vitrectomy, we will determine if the benefit and safety of adding a small implant that will be filled with medication called Susvimo is better with limited laser treatment.

Traditional opioid analgesia is a method to treat moderate to severe pain. However, the use of opioids is not without risks. When treating acute pain, patients may have hypotension, respiratory depression, hypoxia, nausea and vomiting, irritability and pruritus. The aim of this study was to evaluate the analgesic effect and safety of g-protein-biased μ - opioid receptor agonists Oliceridine and oxycodone in vitrectomy.
