Case Report and Literature Review: Isolated Trochlear Nerve Palsy due to Herpes Zoster Infection.

ABSTRACT:

Trochlear nerve palsy (TNP) is a common cause of vertical diplopia resulting from superior oblique muscle weakness. While herpes zoster is a well-documented cause of cranial neuropathies, reports of TNP associated with herpes zoster infection remain limited.
