An evaluation for IIH will include the following:
- A clinical exam
- Imaging studies.Standard imaging studies are usually normal in IIH, however, the doctor may recommend this test to rule out other possible neurological conditions.
- Examination of your visual fieldsby a highly trained neuro-ophthalmologist.
- These exams will include:
- Assessing your peripheral vision
- Determining if you can distinguish different colors
- Using an eye chart to test your central vision acuity (sharpness)
- Dilation of the pupils (to examine the optic discs for swelling)
- Performance of a spinal tap. This spinal tap will confirm the diagnosis by demonstrating a high pressure of cerebrospinal fluid (CSF)
- Medications (Diamox)
- Weight loss
- Stenting of narrowed cerebral venous sinuses
- Placement of a permanent shunt in order to maintain the normal CSF pressure
- Making an opening in the covering of the optic nerve to let the fluid out and relieve pressure on the nerve.
If the neurologist or neuro-ophthalmologist confirms that you have IIH, he or she will recommend a very aggressive and urgent evaluation and treatment plan. If IIH is not treated immediately, permanent and lasting damage can occur to a patient's vision.
