Since treatment of an established PVR has a poor prognosis, prevention remains the surgeon's best hope. The following list shows certain surgeon-controlled variables that may help reduce the PVR risk.
• Timing of surgery. Early vitrectomy in high risk eyes [18, 49] appears to reduce the PVR risk, probably by removing the inflammation-inciting elements from the eye.
• Atraumatic surgery. Avoiding intraoperative complications such as hemorrhage or retinal damage (see above) eliminates certain PVR-in-citing factors.
• Complete surgery. Removal of all vitreous, i.e., posteriorly (PVD), anteriorly (vitreous base and retrolental area), and all proliferative membranes , reduces the medium/scaffold on which cells can proliferate.
• Destruction of RPE cells in certain high-risk injuries. Since these cells are the primary culprit in PVR development, their elimination in the
