BACKGROUND Retrobulbar block is a local anesthetic technique widely used for intraocular surgery. Although retrobulbar anesthesia is considered to be relatively safe, a number of serious adverse events have been reported. To our knowledge, immediate onset of generalized seizures with contralateral hemiparesis after retrobulbar anesthesia has not been reported. CASE PRESENTATION A 62-year-old ...

Ophthalmic anesthesia plays a crucial role in eye surgery. However, the conventional practice of this process is blind procedure, which needle inserted blindly into cadaver. This paper introduces tip tracking system for ophthalmic training focusing on Retrobulbar block procedure. The study presents development prototyped using Hall effect sensor arrays to track 5D magnetized (X, Y, Z, θ, φ ). o...

PURPOSE The authors compared the efficacy of local anesthetics levobupivacaine, bupivacaine, and lidocaine for retrobulbar anesthesia in vitreoretinal surgery. METHODS A total of 135 patients presenting for vitreoretinal surgery under local anesthesia were included in the study. Patients were randomly allocated to one of three groups. Group LB patients received 5 mL of 0.5% levobupivacaine, G...

BACKGROUND/AIM Sub-Tenon's block is nowadays commonly used in ophthalmic surgery because of its safety and efficacy. The aim of this study was to investigate the distribution of the anaesthetic solution with different amounts of hyaluronidase in the retrobulbar space, following an injection into the Sub-Tenon's space. METHODS In this experimental study, 40 pig cadaver heads were used (80 eyeb...

This prospective double-blind study compared the effectiveness of EMLA with alfentanil and placebo in reducing the overall pain during ophthalmic nerve blocks. Seventy-five patients scheduled for cataract surgery were divided into three groups. Patients in the EMLA group had EMLA cream applied over skin areas corresponding to injection sites for retrobulbar and facial nerve blocks one hour befo...

OBJECTIVE To compare the effects of fentanyl or remifentanil in combination with midazolam on hemodynamic parameters, pain, and satisfaction profile in cataract surgery. METHODS This randomized, double blind, prospective study was conducted between 10 and 20th July 2005 at Kudret Eye Hospital, Ankara, Turkey. Patients scheduled for cataract surgery by the phacoemulsification technique were ra...

Two methods of periocular anaesthesia (PI and PII) were compared with the traditional retrobulbar block in a prospective study of 450 patients undergoing elective cataract extraction and intraocular lens implantation. A solution of local anaesthetic containing equal amounts of 2% lignocaine and 0.5% bupivacaine was used in all the groups. Hyaluronidase (75 IU/10 ml of local anaesthetic solution...
