**Core Concept**
Paralytic squint, also known as paralytic strabismus, is a type of strabismus caused by weakness or paralysis of one or more extraocular muscles, leading to impaired eye movement and alignment. This condition can result from various etiologies, including cranial nerve palsies, neurodegenerative disorders, and systemic diseases.

**Why the Correct Answer is Right**
Paralytic squint is characterized by the inability to move the affected eye in the direction of the paralyzed muscle. This results in an abnormal head posture, compensatory movements, and diplopia (double vision) due to the misalignment of the eyes. The affected individual may also exhibit a lack of convergence or divergence, depending on the specific muscle involved.
