Ocular findings in Bell's palsy.

Area of Science:

• Ophthalmology
• Neurology

Background:

• Bell's palsy, a common neurological disorder, affects facial nerve function.
• Ocular complications can arise due to impaired eyelid closure.

Purpose of the Study:

• To investigate the frequency and nature of ophthalmic involvement in Bell's palsy.
• To explore the relationship between facial nerve function and corneal health.

Main Methods:

• Ophthalmic examinations including Schirmer testing, corneal sensitivity, and electromyography were performed.
• Follow-up assessments were conducted one year post-initial examination.

Main Results:

• Sixty-one percent of patients exhibited punctate fluorescein staining of the inferior cornea initially.
• Electromyography showed a strong correlation between orbicularis muscle function and corneal epithelial staining.
• Epithelial defects healed as orbicularis function improved.

Conclusions:

• Minor corneal involvement is common in the acute phase of Bell's palsy.
• Orbicularis muscle function is a key indicator for corneal healing in these patients.
