What is the procedure in which the tendons of the eyeballs are cut to relieve pressure?

The procedure that involves cutting the tendons of the eyeballs to relieve pressure is known as a lateral canthotomy. This surgical intervention is typically performed in cases of ocular emergencies, such as severe orbital compartment syndrome, where there is increased pressure in the orbit that can jeopardize vision and the health of the eye.

During a lateral canthotomy, the outer corner of the eyelids is incised, allowing for access to the orbital tissues. By cutting the tendons, specifically the lateral canthal tendon, the procedure enables the release of pressure that may be caused by swelling or bleeding within the orbit. This alleviation of pressure is crucial for preserving ocular function and preventing permanent damage to the eye structures.

The other procedures listed are not related to the eye or the alleviation of orbital pressure. For instance, laminectomy involves the removal of part of the vertebra to relieve spinal cord pressure. An intra-arterial balloon pump is a device used to assist the heart in pumping blood during certain medical conditions, and a hysterectomy is a surgical procedure to remove the uterus. None of these options pertain to the specific context of eye surgery or the relief of pressure within the eye socket.
