Dry eye syndrome in benign essential blepharospasm.

Area of Science:

• Ophthalmology
• Neurology

Background:

• Benign essential blepharospasm (BEB) is a neurological movement disorder characterized by involuntary eyelid closure.
• Dry eye syndrome is a common ocular surface condition that can cause significant discomfort and visual disturbance.

Purpose of the Study:

• To investigate the relationship between dry eye syndrome and benign essential blepharospasm.
• To determine if dry eye syndrome is a significant comorbidity in patients with BEB.

Main Methods:

• Retrospective analysis of 144 patients diagnosed with benign essential blepharospasm.
• Schirmer I tear tests were performed on all participants.
• Tear test scores were analyzed in relation to patient age, sex, and BEB severity.

Main Results:

• 86.8% of patients with BEB had Schirmer test values below 15mm, indicating dry eye syndrome.
• Dry eye syndrome was strongly associated with BEB, independent of patient age, sex, or BEB severity.
• No significant correlation was found between dry eye severity and age or BEB severity.

Conclusions:

• Dry eye syndrome and benign essential blepharospasm are closely associated conditions.
• Ophthalmologists should consider dry eye syndrome in the diagnostic workup for BEB.
• While dry eye treatment may alleviate some symptoms, specific treatments for BEB, such as botulinum toxin injections, are necessary.
