ABSTRACT
PURPOSE: To investigated the prevalence and risk factors of epiretinal membrane (ERM). SUBJECTS AND METHOD: Five hundred eyes of 500 patients (202 men and 298 women, average age 74.9), who underwent cataract surgery in Otsuka Eye Clinic one or two months before the survey, were examined using spectral-domain optical coherence tomography (OCT). RESULTS: ERMs were observed in 43 eyes (8.6%) and 31 eyes (6.2%) were diagnosed as idiopathic ERM. Idiopathic ERM was significantly associated with age, but not with gender, best-corrected visual acuity after cataract surgery or diabetes. Only 4.8 percent of idiopathic ERM patients had subjective symptoms detected by the Amsler chart. CONCLUSIONS: The prevalence of ERM was 8.6% and of idiopathic ERM 6.2%. The most prevalent risk factor of idiopathic ERM was aging.

A case of subarachnoid hemorrhage (SAH) resulting from a ruptured intracranial dissecting aneurysm of the internal carotid artery (ICA) is reported. A 58-year-old woman presented with headache and vomiting. A CT showed diffuse SAH. A cerebral angiography demonstrated a dissecting aneurysm at the C2 segment of the right ICA. In the present case, trapping with STA-MCA anastomosis was performed and the postoperative course was uneventful. Postoperative follow-up cerebral angiogram detected no aneurysm. SAH caused by the rupture of a dissecting aneurysm of the ICA has been considered rare. To our knowledge, there have been only 29 cases. We discuss the clinical characteristics with a review of the literature.

A case is reported of a patient with simultaneous subdural hematoma and intracerebral hemorrhage associated with a ruptured intracranial mycotic aneurysm. A 65-year-old woman, with a history of low grade fever for over a month, presented with disturbance of consciousness. A CT showed bilateral acute subdural hematomas and parenchymal hematomas in the occipital lobes. Cerebral angiography demonstrated a distal middle cerebral aneurysm. Cardiac ultrasonography showed a verruca at the mitral valve. The incidence of ruptured mycotic aneurysm presenting with acute subdural hematoma is extremely rare. To our knowledge, there have been only seven cases. The present case is discussed with reference to a review of the literature.
