Abstract:AIM: To investigate the features of idiopathic intracranial hypertension(IIH)in the patients firstly visit the ophthalmologic clinical practice.
METHODS: Six patients with 12 eyes were enrolled in this study. The predisposition, symptom, visual acuity, ocularfundus, visual field, ocular aligment, cerebral magnetic resonance imaging(MRI)and magnetic resonance venography(MRV), cerebro-spinal fluid(CSF)suppressor and biochemical analysis were recorded and analyzed.
RESULTS: The predispositions included catching a cold, anxiety reaction and taking doxycycline orally. The symptom included paroxysmal darkness, blurred vision, diplopia, and headache. The visual acuity remained normal or decreased mildly. The papilledema could be found in the ocular fundus examination. Normal visual field or enlargement of physiology scotoma, paralysis of lateral rectus in ocular aligment, normal cerebral MRI and MRV, and normal CSF biochemical results were the feature of these patients except the increased CSF suppressor between 250 and 300mmH2O.
CONCLUSION: The detailed examination of central nerve system is essential for patients firstly visit the ophthalmologic clinical practice withpapilledema and lateral rectus paralysis to diagnose or exclude the possibility of IIH.
