Abstract
Case summary
Case 1 was a 27-year-old male who presented with complaints of headache and vomiting for 2 months and blurred vision in both eyes. The best-corrected visual acuity (BCVA) was 1.0 in the right eye and 1.0 in the left eye. A visual field (VF) examination revealed a binocular peripheral VF defect and optical coherence tomography (OCT) and a fundus examination indicated optic disc swelling in both eyes. Brain magnetic resonance imaging (MRI) showed no specific finding but magnetic resonance venography revealed filling defect signs in the transverse sinus and a cerebrospinal fluid examination indicated elevated intracranial pressure (ICP). Case 2 was a 54-year-old female who came to our hospital with suspicion of bilateral optic disc swelling. The BCVA was 0.9 in the right eye and 1.0 in the left eye. A VF examination revealed an inferior-temporal VF defect and blind spot enlargement in the right eye. OCT and a fundus examination showed optic disc swelling in both eyes. Brain MRI showed no specific finding but magnetic resonance venography revealed a decrease in blood flow in the transverse sinus, sigmoid sinus. A cerebrospinal fluid examination indicated elevated ICP.
