Abstract:  Objective To evaluate the efficacy and safty of lumboperitoneal shunt (LPS) for treatment of idiopathic intracranial hypertension (IIH). Design Retrospective case series. Participant 114 IIH patients with LPS from Beijing Tongren Hospital. Methods The medical records of patients before and after LPS surgery were reviewed. The patients were followed up for 3.4±1.2 (2-16) months. Main Outcome Measures Best corrected visual acuity (BCVA), visual field, papilledema, headache and complications. Results 62 cases (59.6%) with preoperative BCVA<0.05 reduced to 30 cases(28,8%) after LPS (P<0.05). 66 cases(70.2%) of visual field defect were improved. Mild papilledema occurred in 58 cases(50.9%) before LPS, and severe papilledema in 54 cases(47.4%), while 25 cases(21.9%) remained with mild papilledema, and 7 cases(6.1%) with severe papilledema after LPS. Headache in 67 cases (93.1%) alleviated 3 months after LPS. During the follow-up period, shunt obstruction developed in 3 cases and shunt infection in 2 cases postoperatively. 12 cases underwent shunt adjustments, with an average of 1.4 times. Conclusion The short-term follow-up in this study showed that LPS can effectively relieve the visual acuity, visual field, headache and papilledema caused by IIH. (Ophthalmol CHN, 2020, 29: 255-259)
