Summary
Optic nerve sheath fenestration (ONSF) surgery can improve or preserve vision in patients with pseudotumor cerebri experiencing vision loss despite Diamox treatment. This retrospective study shows ONSF benefits for progressive visual field and acuity decline.
Area of Science:
- Ophthalmology
- Neurosurgery
Background:
- Pseudotumor cerebri (idiopathic intracranial hypertension) can cause progressive visual field and acuity loss.
- Medical management with acetazolamide (Diamox) is the first-line treatment.
- Surgical intervention may be necessary for refractory cases.
