Abstract
Two hundred and seventy-two patients with idiopathic blepharospasm were reviewed to establish the role of local eye disease in their illness. The majority of patients (57%) had symptoms at the onset of their illness such as dryness of the eyes, grittiness, irritation or photophobia suggesting eye lid or ocular surface disease. Detailed ophthalmological examination at the time of presentation had been carried out in 170 of the 272 cases; 64% of these patients had ocular symptoms, and 40% had demonstrable ocular surface or eye lid pathology. Such pathology was usually bilateral, chronic and resistant to local treatment. Blepharospasm developed in these patients after a long latent period, often of many years. Unilateral pathology was acute, normally responded well to local treatment, but was followed by the development of bilateral blepharospasm usually within six months. Amongst all 272 patients, those without ocular symptoms at presentation rarely developed them subsequently; if they did, there were no abnormal signs.
The data suggest that ophthalmological disorders may trigger idiopathic blepharospasm in a substantial proportion of cases predisposed to develop this condition.
