Purpose: To examine the relationship between the extent of subarachnoid hemorrhage and intraocular hemorrhages in patients with subarachnoid hemorrhage.
Subjects And Method: A total, of 63 patients (25 men and 38 women, mean age 58 years). The subarachnoid hemorrhage quantity was graded according to the Fisher scale and compared with hemorrhages in the ocular fundus.
Results: Either vitreous or preretinal hemorrhages in either one or both eyes (vitreous hemorrhages) were present in 16 patients (25%). Retinal hemorrhages in either one or both eyes (retinal hemorrhages) were present in 12 patients (19%). Intraocular hemorrhage was absent in the other 35 patients (56%). The incidence of vitreous hemorrhage tended to be higher than the incidence of retinal hemorrhage or of the absence of hemorrhage as the rate of subarachnoid hemorrhage increased (Kruskal-Wallis, p < 0.05). There was no significant correlation between retinal hemorrhages and the absence of hemorrhage in the Fisher grade IV chi2, p > 0.05).
Conclusion: The onset of vitreous hemorrhage appears to be related to the extent of subarachnoid hemorrhage but the onset of retinal hemorrhage is not.

Three monoclonal antibodies directed against specific forms of the amyloid-β (Aβ) peptide have been granted accelerated or traditional approval by the FDA as treatments for Alzheimer disease, representing the first step towards bringing disease-modifying treatments for this disease into clinical practice. Here, we review the detection, underlying pathophysiological mechanisms and clinical implications of amyloid-related imaging abnormalities (ARIA), the most impactful adverse effect of anti-Aβ immunotherapy. ARIA appears as regions of oedema or effusions (ARIA-E) in brain parenchyma or sulci or as haemorrhagic lesions (ARIA-H) in the form of cerebral microbleeds, convexity subarachnoid haemorrhage, cortical superficial siderosis or intracerebral haemorrhage.

Objective: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality rates. In particular, functional outcomes of SAH caused by large or giant (≥ 10 mm) ruptured intracranial aneurysms are worsened by high procedure-related complication rates. However, studies describing the risk factors for poor functional outcomes specific to ruptured large/giant aneurysms are sparse.

Although many institutions increasingly perform endovascular coiling instead of microsurgical clipping as the primary treatment for ruptured aneurysms, there remains ongoing debate regarding the optimal treatment strategy for ruptured middle cerebral artery (MCA) aneurysms. Therefore, we compared the outcomes of clipping and coiling for treating ruptured MCA aneurysms. A total of 155 ruptured MCA aneurysms that were deemed eligible for both clipping and coiling were retrospectively reviewed.

To evaluate the safety and efficacy of staged coiling followed by flow diverter (FD) in the treatment of ruptured intracranial aneurysms(RIAs). A retrospective analysis was conducted on 20 patients with RIAs treated with staged coiling followed by FD at a single center, between April 2015 and September 2024. Patient demographics, aneurysm characteristics, clinical and imaging outcomes were reviewed.
