The Authors report two cases of central nervous system complications after retrobulbar block. These complications have a 0.044% incidence in 4500 subsequent cases of retrobulbar blockade studied from 1981 to 1990. The Authors attribute the respiratory arrest and coma to direct access of the anesthetic to the central nervous system along the subdural space in the optic nerve sheath.

Perioperative analgesic effects of a modified supratemporal retrobulbar block in dogs undergoing corneal and endocular surgery.
J Small Anim Pract
January 2025
Department of Veterinary Science, University of Turin, Grugliasco, Italy.
Objectives: To evaluate the perioperative efficacy of a modified supratemporal retrobulbar block in dogs undergoing ocular surgery.
Materials And Methods: In this prospective randomized clinical trial, dogs were premedicated with dexmedetomidine (1 mcg/kg im) and methadone (0.1 mg/kg im), induced with propofol to effect and maintained with isoflurane (FE'Iso 1.
Peribulbar vs. incisionless sub-Tenon's blocks: a retrospective cohort study.
Eur J Med Res

Department of Anesthesiology and Reanimation, Faculty of Medicine, Osmangazi University, Büyükdere Mh, Odunpazarı, 26040, Eskişehir, Turkey.
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.

Article Synopsis
- The study investigates the supratemporal retrobulbar block as an anesthetic technique in cats, addressing its effectiveness and injection methods.
- A modified injection of a specific mixture was performed on cadavers, showing a high success rate in contrast agent spread and good distribution around the optic nerve.
- In a clinical setting with 12 cats, the retrobulbar group experienced fewer anesthetist interventions compared to the control group, indicating a potential advantage of the supratemporal approach for surgeries.
Background: The purpose of the study was to compare the mean post-operative pain in patients undergoing phacoemulsification for cataract with topical anaesthesia vs. retrobulbar anaesthesia.
Methods: An interventional study was carried out in a tertiary care hospital of Islamabad.
Incidence of strabismus surgery after vitreoretinal surgery.
J AAPOS
December 2024
Des Moines University Medical School, Des Moines, Iowa.
Strabismus following other intraocular surgery has several well-described etiologies. Vitreoretinal surgeries are the most likely to require retrobulbar anesthesia and exoplants, two commonly associated risk factors for postoperative strabismus. A reliable assessment of the incidence of strabismus secondary to other ocular surgery has not been established.
