Peribulbar injection is given in: September 2009
## **Core Concept**
Peribulbar injection is a regional anesthesia technique used in ophthalmology. It involves injecting anesthetic around the eyeball to provide analgesia and akinesia for ocular surgery. The goal is to block the nerves supplying the eye.
## **Why the Correct Answer is Right**
The correct answer, , involves injecting the anesthetic into the peribulbar space. This space contains the nerves and vessels supplying the eye. By depositing the anesthetic here, effective blockade of these nerves is achieved, ensuring the eye and surrounding muscles are immobilized and pain-free during surgery.
## **Why Each Wrong Option is Incorrect**
- **Option A:** Injection in this location would not effectively block the nerves supplying the eye, as it is too anterior and does not target the peribulbar space directly.
- **Option B:** This location might be related to other types of blocks or injections but is not the correct site for a peribulbar injection.
- **Option D:** Similarly, this option does not accurately describe the peribulbar space or the technique used for peribulbar anesthesia.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that peribulbar anesthesia is often preferred over retrobulbar anesthesia because it has a lower risk of complications such as globe perforation and retrobulbar hemorrhage. The peribulbar block provides excellent conditions for ocular surgery with a safer profile.
## **Correct Answer:** . Peribulbar space.
