- CT or MRI - the ventricles, in contrast to hydrocephalus, are normal or reduced in size
- visual field charting - demonstrate enlarged blind spot and peripheral field construction
- lumbar puncture, if not contraindicated by clinical features and pressure measurement
- monitor intracranial pressure if in doubt as to the diagnosis
