Abstract

Facial nerve (7th cranial nerve) palsy is often idiopathic (formerly called Bell palsy). Idiopathic facial nerve palsy is sudden in onset, unilateral peripheral facial nerve palsy. Objective: The aim was to study Ophthalmic clinical features of patients of facial Nerve palsy Methodology: In this Retrospective observational study we have analyzed 60 eyes from 60 facial nerve palsy patients who were referred to our ophthalmic clinic of our hospital. Result: The most common ophthalmic signs caused by facial nerve palsy were lagophthalmos (45 eyes, 75%), corneal epithelium defect (35 eyes, 58.33%), and conjunctival injection (30 eyes, 50%). We have divided these signs into categories: eyelid, cornea, conjunctiva, and eye movement. Signs related to the eyelid were lagophthalmos (45 eyes, 75.0%),ptosis (30 eyes, 50%), lid laxity, entropion, ectropion, and swelling. Corneal signs were corneal epithelium defect (35 eyes, 58.33%) and corneal opacity (6 eyes, 10%). Conjunctival signs were conjunctival injection (30 eyes, 50%) and chemosis (8, 13.33%).Signs related to eye movement were paralytic strabismus (15 eyes, 25%), LOM (7 eyes, 11.6%), diplopia (8 eyes, 13%), and nystagmus (4 eyes ,6.66%). Other symptoms were epiphora (21 eyes, 35%) and dry eye syndrome (4 eye, 6.66%)
