Summary

This study investigated the effect of desflurane and propofol anesthesia on visual acuity in patients in prone position for spinal surgery. Many trials have investigated the effects of different anesthetic agents on intraocular pressure, propofol may reduce intraocular pressure more than other intravenous anesthetics.

Conditions

  • Vision; Disorder, Loss

Interventions

PROCEDURE

Desflurane Group

General anesthesia will be held using desflurane in end- tidal concentration according to target value of entropy levels (between 40 and 60).

PROCEDURE

Propofol Group

General anesthesia will be held using Schnider effect model for propofol (target control anesthesia). Titration will be done according to target value of entropy levels (between 40 and 60).
