Enrolled patients will be randomized into 1 of 2 possible treatment groups: Group A patients underwent endolaser PRP with a range of 200-300 shots during PPV, whereas Group B patients underwent endolaser PRP with a range of 500-600 shots during PPV. Simple randomization will allocate subjects into treatment groups during PPV. Once all applicable maneuvers (including satisfactory hemostasis) are completed by the surgeon apart from endolaser PRP, a coin toss simulation program will randomize subjects into treatment groups.
In this randomized clinical trial, the authors compare two cohorts receiving different endolaser spot amounts with similar laser settings in PDR subjects naïve to PRP undergoing PPV for the indication of VH.
