What condition is characterized by the eye hanging from the socket?

The condition where the eye hangs from the socket is known as ocular extrusion. This situation typically occurs due to severe trauma or injury to the eye, resulting in the eyeball being pushed or pulled outward from its normal position within the eye socket. This can be an alarming and serious condition requiring immediate medical attention to address both the physical injury and the potential loss of vision.

The other options present conditions that affect the eye but do not describe the eye physically hanging from the socket. Corneal abrasion refers to a scratch on the surface of the cornea, which, while painful and serious, does not involve the eye being displaced. Retinal detachment is a condition where the retina detaches from the back of the eye and may cause vision loss but doesn't involve the eye's structural integrity being compromised to the degree of hanging. Glaucoma is a group of eye diseases that damage the optic nerve often associated with increased intraocular pressure, which impacts vision and eye health but is unrelated to the physical displacement of the eye. Thus, ocular extrusion is the only option that accurately describes the condition where the eye is hanging from the socket.
