Due to high prevalence of vitrectomy surgery, and the importance of anesthetic technique in conducting an uncomplicated surgery, we decided to do this study. Materials and Methods: This prospective randomized study was conducted on 80 patients 40-80 years old candidating deep vitrectomy sugery under general anesthesia that were categorized into II and III Class by American Society of Anesthesiologist (ASA). Patients were randomly allocated to two groups of 40 members. Anesthesia was induced in

For maintaining anesthesia, patients from I group receiVed 1.2% isofluran with 50% O2 in air at 4L/min and infusion of remifentanil (0.1 mg.kg-1.min-1). But in the P group, we used propofol up to 10mg/kg /hr with infusion of remifentanyl. Propofol and isoflurane in fusion was discontinued with the last surgical stitches, but remifentanil infusion continued in both groups until the eye was covered with shield. Hemodynamic variables were recorded just before the induction of anesthesia and in different time intervals till discharging of the patients from the recovery room. Then, data were compared. Results: Results showed that there is a significant change in propofol group compared to isofluran in deep vitrectomy surgery operations. Conclusion: Hemodynamic changes are more significant in maintaining propofol anesthesia when compared with isoflurane.
