The ptosis from inactivation of the superior tarsal muscle causes the eye to appear sunken in, but when actually measured, enophthalmos is not present. Patients may have apparent enophthalmos (affected eye looks to be slightly sunken in) but this is not always the case. It inactivates the superior tarsal muscle which produces ptosis. It inactivates the dilator muscle and thereby produces miosis. Interruption of sympathetic pathways leads to several implications. heterochromia iridum (in congenital Horner's syndrome).unilateral straight hair (in congenital Horner's syndrome) the hair on the affected side may be straight in some cases.bloodshot conjunctiva, depending on the site of lesion.inability to completely close or open the eyelid.Enophthalmos (sinking of the eyeball into the face).ptosis (drooping of the upper eyelid).Signs that are found in people with Horner's syndrome on the affected side of the face include the following: Once the syndrome has been recognized, medical imaging and response to particular eye drops may be required to identify the location of the problem and the underlying cause. The nerves are part of the sympathetic nervous system, a division of the autonomic (or involuntary) nervous system. The nerves of the sympathetic trunk arise from the spinal cord in the chest, and from there ascend to the neck and face. It is characterized by miosis (a constricted pupil), partial ptosis (a weak, droopy eyelid), apparent anhidrosis (decreased sweating), with apparent enophthalmos (inset eyeball). The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk. Horner's syndrome, also known as oculosympathetic paresis, is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged.
