Changes in Intraocular Pressure in Anesthetized Prone Patients

Abstract

IOP increases when anesthetized patients are placed in the prone position.

Efeito da rotação da cabeça na pressão intraocular em decúbito ventral: estudo randomizado

“…These fi ndings are in accordance with previous studies 8,9 . Our results have also suggested that when patients were positioned prone with their heads rotated 45 o laterally, IOP in the upper positioned eyes were signifi cantly lower than lower positioned eyes and IOP of the patients positioned prone without head rotation.…”

“…Since ocular perfusion pressure is commonly defi ned as the difference between mean arterial pressure (MAP) and IOP, the authors drew attention to the fact that ocular perfusion pressure could decrease despite maintenance of normotension during surgery in prone position 8 . In a similar study, Hunt et al 9 also studied patients undergoing spinal surgery and found that IOP increased when anesthetized patients are placed in prone position. Those in prone positions were signifi cantly higher than supine positions.…”

Intraocular pressure elevation in the early postoperative period after vitrectomy for rhegmatogenous retinal detachment

“…It is reported that patients who have undergone spinal surgery in the prone position showed elevated IOP during anesthesia [25,26]. Because all patients in our study were kept in the prone position after surgery, it could have had an influence on their postoperative IOP.…”

Erblindung nach nichtophthalmologischen Eingriffen

“…-Obwohl bekannt ist, dass der intraokuläre Druck in BauchIagerung erhöht ist [19], gibt es bislang keine Daten zum Einfluss der Flexion bzw. orthograden oder Seitlagerung des Kopfes in Bauchlagerung auf den intraokulären Druck.…”

“…Demzufolge sind gerade Glaukompatienten gefähr-det, eine ischämische N.-opticus-Neuropathie zu erleiden [54]. Zudem wird der intra okuläre Druck durch eine Bauchlagerung erhöht [19]. [31].…”
