What does EOM palsy affect?

EOM palsy, referring to extraocular muscle palsy, specifically affects the extraocular movements of the eyes. This condition occurs when there is damage or dysfunction in the cranial nerves that control the muscles responsible for moving the eyes. When extraocular movements are impaired, it leads to difficulties in moving the eyes in various directions, which can result in symptoms such as double vision or misalignment of the eyes (strabismus). Understanding the role of extraocular muscles and the major cranial nerves involved—particularly the oculomotor, trochlear, and abducens nerves—is critical for diagnosing and managing conditions associated with EOM palsy. This condition does not impact speech, facial symmetry, or any functions related to the anal sphincter, making the correct answer focused specifically on the movement of the eyes.
