Blepharospasm is an uncontrolled spasmodic contraction of the orbicularis muscles of the eye resulting in an abnormal tic or twitch of eyes. It usually lasts for seconds to minutes but in severe cases eyes may be closed for hours. It may be essentially benign or secondary due to a lesion in basal ganglia, pyramidal tract, and trauma, local pathology in the eyes or drug induced. Here we are presenting a case of psychogenic blepharospasm. A 65 year old woman presented with a history of episodic inability of opening her eyes for the past 6 months. She had repeated abrupt closure of eyes which would persist for 1 hour. It made her socially and interpersonally disabled. Systemic and neurological causes were ruled out by detailed physical examinations and investigations including neuroimaging. Following poor response to oral medications she was injected with 7 units of Botox only in the muscles of the right eye. But within seconds she received relief in both eyes. During the next session she received a needle prick in one eye with no medication and immediately both of her eyes opened from a tightly closed position. In this case the patient reported stress due to increased workload around the house. From our case it depicts that a true movement disorder is often difficult to distinguish from functional disorder. So evaluation and management of patient's external and internal stress will be of immense help before conducting any invasive treatment.
