A 39-year-old woman with rheumatoid arthritis, sleep apnea and a body mass index of 55 presented with nausea, vomiting and floaters in the right eye for two days. Two weeks prior, she developed positional headaches, blurry vision and transient visual obscurations. On presentation, her best corrected visual acuity was 20/25 in each eye, there was no relative afferent pupillary defect and the examination of external structures and anterior segment was unremarkable.\nFunduscopic examination revealed Frisen grade 4 papilledema in the right eye with vitreous, subretinal and intraretinal hemorrhages, and grade 3 in the left eye with flame-shaped hemorrhages (A, ).\nHead CT with contrast appeared normal, an MRI was not possible due to body habitus and weight restrictions. Lumbar puncture under fluoroscopic guidance revealed opening pressure of 310 mm CSF with normal composition. Humphrey visual field 24-2 SITA Fast was reliable with an enlarged blind spot and a few central changes in the right eye (mean deviation −4.00 dB) and was essentially full with mild central depression in the left eye (mean deviation −3.55 dB).\nShe was started on acetazolamide 500 mg twice daily, which was titrated up to 1500 mg twice daily with gradual resolution of symptoms over a month. At two month follow up, the vitreous hemorrhage had resolved and there was marked improvement in the papilledema bilaterally ( C, D).
A 41-year-old man complaining of left visual disturbance visited our department. He had a history of IVH associated with moyamoya disease three months ago. He was comatose at the initial presentation. Computed tomography (CT) at the first visiting hospital demonstrated IVH with hydrocephalus (). Cerebral angiography showed severe bilateral stenosis at the distal internal carotid artery and basal moyamoya vessels. It was compatible with moyamoya disease (). Emergent extraventricular drainage was performed. His mentality gradually improved to alert. Ophthalmologic examination at our hospital detected a vitreous hemorrhage in his left eye (), with right eye remaining normal (). In spite of three months conservative care, his visual acuity was not improved. Vitrectomy with epiretinal membrane removal was performed (). After operation his left visual acuity was recovered.
