A Rare but Life Threatening Risk of Peribulbar Anaesthesia

Peribulbar anaesthesia is the most commonly used anaesthetic technique in most of the intraocular surgeries especially in glaucoma and vitreoretinal surgeries. This is a case study of a 70 year old man who underwent a combined glaucoma and cataract surgery under Peribulbar anaesthesia and developed loss of consciousness and untoward complications of brainstem anaesthesia. Though the complications are very rare with Peribulbar anaesthesia, one need to be extremely careful and should be equipped with the necessary facilities to tackle the life threatening implications� if any occurs in the operation theatre.
