Abstract

Background: To investigate the effect of cerebrospinal fluid (CSF) shunting on quantitative perimetry and papilledema in patients with uncontrolled idiopathic intracranial hypertension (IIH). Methods: We retrospectively reviewed all cases of IIH with CSF shunting at our institution between 2004 and 2011. Perimetry was performed before and after surgery in 15 patients, and the mean deviation (MD) was compared before and after surgery to assess the effect of the intervention. Results: Fourteen of the IIH patients were female and 1 was male. The average age was 34 years. CSF shunting resulted in significant improvement in the perimetric results with an increase in the MD of 5.63 ± 1.19 dB (P < 0.0001). Additionally, average retinal nerve fiber layer (RNFL) thickness measurement by optical coherence tomography decreased by 87.27 ± 16.65 m (P < 0.0001), and Frisen papilledema grade decreased by 2.19 ± 0.71 (P < 0.0001). Conclusions: Our results suggest that CSF shunting results in improvement in perimetry, RNFL swelling, and papilledema grade in patients with IIH.
