Association of blepharospasm with parkinsonism, and essential tremor

Rana,  M.A., Rana,  A.Q.


To study the association of blepharospasm with parkinsonism, and essential tremor.


Blepharospasm is characterized by intermittent, involuntary eyelid closure, increased blinking rate, ocular discomfort and dry eyes. There have been many reports that blepharospasm has much higher prevalence in parkinsonism and other movement disorders. We wanted to study the prevalence of blepharospam in parkinsonism, and essential tremor.


We included 300 patients with Parkonsonism. Among these, 270 patients had idiopathic Parkinson's disease, 30 had atypical parkinsonism. Furthermore, we included 250 patients with essential tremor to study the prevalence of blepharospasm. We also followed six patients with blepharospasm to observe presence of other movement disorders.


Among the 300 patients with parkinsonism, 6 patients had blepharospasm. Among these, 3 patients who had blepharospasm with ALO had progressive supranuclear palsy. Among the 270 patients with Parkinson's disease, 6 of them had Blepharospasm. 1 patient with Corticobasal degeneration had blepharospasm. None of the patients with essential tremor had blepharospasm. Two patietnts with blepharospam developed PD after several years.


Blepharospasm has increased prevalence in parkinsonism but may not have an association with essential tremor.
