Iatrogenic retinal breaks caused by infusion fluid during pars plana vitrectomy

Infusion flow related retinal breaks in 25G vitrectomy

“…Despite the advances in instrumentation and surgical techniques, IRBs remain a serious intraoperative complication resulting in additional surgical steps and possibly poor visual results (Steel & Charles ; Bilgin et al. ). New‐generation vitrectomy machines have refined the pressure control system to stabilize intraoperative pressure compensation and maintain constant IOP independent of aspiration flow rates during cutting/aspiration modes.…”

“…Bilgin et al. () had recently discussed three patients where insult by infusion jet of fluid precipitated new breaks. The indication of vitrectomy was different in these patients, and retina was already compromised by primary pathology such as retinal detachment, diabetic retinopathy and oil‐filled eye after primary retinal detachment surgery.…”

“…Sugiura et al. () studied intra‐operative IOP fluctuation during different surgical maneuvers in experimental animals using Alcon constellation vision system. Authors noted that with 25G vitrector in cutting mode under standard flow rates, it took 2.6 seconds to return to preset IOP levels after the initial drop.…”

Iatrogenic retinal breaks in ultrahigh-speed 25-gauge vitrectomy: a prospective study of elective cases

“…The occurrence of IRB remains an important complication after PPV for elective cases 15. Excessive vitreous traction on the retina is the leading cause of such breaks.…”

“…IRB can also be caused by infusion fluid, occurring during the fluid–air exchange surgical step 15. Intraoperative retinal breaks are also related to PVD induction 10 13.…”
