Hi.. Thanks for the query.. papilledema can have various causes.. By doing MRI/CT scan any space occupying lesions of the brain are ruled out.. If MRI comes out clear just don t worry.. There are other reasons in the eye also for papilledema. What is the vision in the eye with papilledema? Are you a hypertensive or obese? In obese persons there can be benign intracranial hypertension which causes papilledema.. If you are a hypertensive there will be associated changes in the retina.. Any tumours in the orbit should also be ruled out by CT/MRI orbits... A lumbar puncture should not be performed when there is a papilledema unless it is necessarily indicated.. A complete eye check up can be done including peripheral retinal evaluation and visual fields test if required... Consult an ophthalmologist just to make sure that any eye related problem is not picked up.. Hope this information helps you.. Take care..
