Definition

unilateral pupil dialation is a #1 neurologic emergency if it is w/in a certain time frame.. if it accompanies a ptosis ( third nerve palsy) , it can indicate a PCA (posterior communicating artery aneurysm). #2 a "lesion in the occipital lobe" as the optic tract transverses the occipatal lobe, although the ptosis is usually the first sign, followed by headaches and balance issues, the patient ultimately needs to go to the emergency room for an evaluation. sometimes it is chemical from certain drugs, and even diabetes. if the patient is having headaches or a single headache event that is more intense than the average headache, it could indicate a bleed in the subarachnoid space, especially if its the "the worst headache i ever had". regardless the patient needs a MRA!!! with speical sections thru the circle of willis / and MRI with and without contrast. a ct scan if an emergency is occuring and an maybe a cerebrel angiogram. a neurosurgeon should evaluate the patient at some point, if it is a surgical issue, or if there is doubt. if there is a head injury involved, the patient should be seen immedialtely,as this could be life or death. common sense also plays a role here to.
