“…Several surgical procedures have been reported as the primary triggers of SO, including cyclo-destructive procedures, cataract surgery, glaucoma filtration surgery, evisceration, and retinal laser photocoagulation [ 5 ]. Since the 1980s, the association between vitreoretinal (VR) surgery and SO has been investigated, and in recent years, ocular surgery, especially vitrectomy, has become an increasingly prevalent risk factor for SO [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. However, most of these studies are heterogeneous, and they did not highlight well whether VR surgery alone or in combination with other surgical procedures in eyes with or without a history of previous ocular surgery or trauma represented the inciting event causing SO.…”
