This technique was first applied by Davis. In peribulbar block, local anaesthetic is injected to the peripheral spaces of the orbit. The anaesthetic diffuses into the muscle cone and eyelids, causing global and orbicularis akinesia and anaesthesia. After injection, orbital compression is applied for around 15 minutes.

Retrobulbar block can be used successfully for corneal transplantation but may require a supplemental facial nerve block. Retrobulbar block can block levator palpebrae muscle but not orbicularis oculi. Several techniques for facial nerve block can be used in conjunction with retrobulbar block. [citation needed]
This outpatient procedure was most commonly performed under monitored anesthesia care using a retrobulbar block or peribulbar block or a combination of topical and subtenon (Tenon's capsule) anesthesia. Due to the higher risks associated with bulbar blocks, topical analgesia with mild sedation is becoming more common.
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
Topical, sub-tenon, peribulbar, or retrobulbar local anaesthesia is generally used, usually causing little or no discomfort. [52] [49] Injections may be used to block regional nerves and prevent eye movement. [7] Topical anaesthetics are most commonly used, placed on the globe of the eye as eyedrops (before surgery), or in the globe (during ...
Manchester police noticed a strong smell of bleach when they approached the father and son’s home in the 100 block of Baxter Heights during a welfare check, according to the file.
Anaesthesia may be placed topically as eyedrops or injected next to (peribulbar) or behind (retrobulbar) the eye [6] or sub-tenons. Local anaesthetic nerve blocking has been recommended to facilitate surgery. [2] Topical anaesthetics may be used at the same time as an intracameral lidocaine injection to reduce pain during the operation. [6]
