Damage to this muscle or its innervation can cause ptosis, which is drooping of the eyelid. Lesions in CN III can cause ptosis, because without stimulation from the oculomotor nerve the<unk><unk>  cannot oppose the force of gravity, and the eyelid droops. Ptosis can also result from damage to the adjoining superior tarsal muscle or its sympathetic innervation. Such damage to the sympathetic supply occurs in Horner's syndrome and presents as a partial ptosis. It is important to distinguish between these two very different causes of ptosis. This can usually be done clinically without issue, as each type of ptosis is accompanied by other distinct clinical findings. The ptosis seen in paralysis of the<unk><unk><unk>  is usually more pronounced than that seen due to paralysis of the superior tarsal muscle.
