Background Ophthalmic procedures are increasingly being performed under regional anesthesia techniques such
as peribulbar and incisionless sub-Tenon’s blocks. The aim is to compare peribulbar block with incisionless sub-Tenon’s
block in terms of perioperative complications in patients who underwent cataract and vitreoretinal surgeries.
Methods The patients who underwent cataract or vitroretinal surgery under peribulbar block or incisionless sub-
Tenon’s block were included in the study. Two groups were compared each other in terms of anesthesia-related
complications.
Results A total of 125 patients [peribulbar block (N
=
48) and incisionless sub-Tenon’s block (N
=
77)] were included
in the study. All basic characteristics and perioperative hemodynamic parameters were similar between the groups.
One (0.8%) patient in the peribulbar block developed retrobulbar hemorrhage, whereas there was no major com-
plication in the incisionless sub-Tenon’s group (P
=
0.389). At 15th minutes after block and at the end of the opera-
tion, minor complications including chemosis and subconjunctival hemorrhage were observed significantly lower
in the peribulbar block group in comparison to the incisionless sub-Tenon’s block group (P < 0.05).
Conclusions Minor complications including subconjunctival haemorrhage and chemosis were more common
in the incisionless sub-Tenon’s block; however, this difference was statistically balanced on the first postoperative day.
One patient in the peribulbar block developed retrobulbar hemorrhage, whereas there was no major complication
in the incisionless sub-Tenon’s block. According to those results, incisionless sub-Tenon’s block seems to be a safe
and reliable alternative for ophthalmic procedures.
