Fifty five patients with Meige's syndrome were examined for clinical and demographic features. The mean age of onset was 52.3 years. The peak age of onset was in the sixth decade with a male to female ratio of 1.111. The mean duration of illness was 3.7 years. Commonest initial symptom was increased blinking, seen in 30 cases (54.5%). Twenty five patients (45.4%) had complete syndrome of blepharospasm with oromandibular dystonia, whereas 24 patients (43.6%) had blepharospasm alone and the rest (6 patients, 10.9%) had oromandibular dystonia. The extension of spasm beyond cranial muscles was observed in 10 patients (18.1%). Eleven patients had family history of dystonia or other extrapyramidal disorders. Incidence of depression was high in these cases.
