Purpose: The aim of this paper is to present the current possibilities in idiopatic intracranial hypertension (IIH) diagnostics. Optical coherence tomography belongs to these possibilities in last few years. The necesarry interdisciplinary co-operation of ophthalmologist and neurologist concerning in IIH patients is pointed out in the mentioned case reports. Material and methods: The issue of diagnostics and care of IIH patients is presented in two case reports. Results: After ophthalmological and neurological examination the diagnosis of idiopathic intracranial hypertension was assessed and the treatment with acetazolamide was started. The patients have been observed in The department of ophthalmology University hospital in Pilsen during the run of the disease by the neoroophthalmologist. The edema of optic nerve has been monitored by fundoscopy and optical coherence tomography. Initially highly distended retinal nerve fiber layer thickness has been decreased with the normalizing of optic nerve head appearence. The patient´s difficulties have gone off during couple of month and the edema of optic nerve papilla has disappeared. According to the education and the regime acquisition our two patients reduced their body weight, so that they influenced favourably the development of their disorder. Conclusion: IIH is consequential disorder causing patient´s crucial restriction in an ordinary lifestyle. It could cause difficult changes in vision. The early diagnosis and proper leading of the therapy is fundamental for the next development of patient´s health.
