Ocular Complications in Laparoscopic Surgery: Review of Existing Literature and Possible Prevention and Treatment

During laparoscopic surgery, ocular complications are possible, sometimes leading to devastating visual losses, hardly susceptible to recovery, although rare. Principal ocular adverse events are represented by corneal abrasions and the perioperative visual loss (POVL). POVL onset is related to intraocular pressure elevations (particularly after patient positioning in Trendelenburg or prone decubitus, depending on the surgical procedure), anesthesiologic factors and patients' characteristics. In the light of evidence from the existing literature, the authors suggest surgical and anesthesiologic measures to prevent and manage ocular complications in laparoscopic surgery. Apart from general recommendations, this article indicates practical guidelines specific for robot-assisted laparoscopic interventions and spinal surgery, as well as laparoscopic colorectal resection, radical prostatectomy, and gynecologic surgery. In conclusion, in order to better manage these complications, it is advisable to develop an interdisciplinary collaboration between surgeons, anesthesiologists, and ophthalmologists, on a procedural and medico-legal level, with the intent of mutual training.
